1. Introduction
 DECT – Digitally Enhanced Cordless Telephone
 3M Peltor DECT-Com II is a wireless duplex intercom system, operating on the
1.8 GHz DECT-frequencies, which is license free in most countries.
 The products in the Peltor DECT-Com II family offer simple and efficient wireless
duplex communication with up to 9 active users talking in full conference.
 Due to low power output and high frequency, it is a short range communication
system. The nominal working range is approximately 150 metres outdoors in line
of sight from the base. The working range may be shorter due to actual
environmental conditions.
2. System Overview
Main unit
There are basically two main versions of the
DECT-Com II main unit:
- Portable
- Base/Portable
There is also an Extension Base/Portable (for
link to external communications devices). This
is rarely used.
New DECT-Com II
Up to 9 simultaneous
portable units in a
conference logged on to a
base unit,
which can also accept a
headset making a total of
10.

3. Out of the Box Start-Up

A DECT-Com II system needs to be charged for 12 hours
before use. The following steps then need to be followed:
1.
Select the base unit from the kit. This is the unit with a
BLACK or RED antenna band.
2.
Place the base unit in the vehicle cradle and position it as
high up in the RRV cab as possible, using a Velcro pad or
other suction kit on the glass.(Do not lie on floor of cab).
3.
Connect the in vehicle cradle to the 12/24V Plug (Cigar
Lead) and insert into the 12/24v socket in the OTP. Check
the blue light on the cradle is on.(If the blue light is not on
get a fitter to check the 12v24v auxiallary socket, and if this
is servicable you will need to change the cradle).
4.
Plug in the throat mic or headset
5.
Switch on the BASE UNIT (ONLY). Always switch on the base
unit before the portables. To do this, press and hold the “M”
button until the LED starts to flash.
WAIT for approximately 20 seconds. The green LED will now flash
more slowly. You will hear “Group One”. The base set is now on.
Now switch on the portable units. These have a GREEN antenna
band. To do this, press and hold the “M” button. With Auto talk
enabled, you will then hear POWER ON. The green LED will start
to flash. After a few seconds you will hear BASE1 GROUP 1. The
Handset is now coupled with the base and working.

•MICROPHONE
Main unit
VOLUME
Audio output level
Steps 1 (min) – 5 (max)
VOLUME BOOST
The audio levels can be increased by +6 dB for
“Ear-plug mode” .
To activate press the “+” button and hold for 10
seconds.
To deactivate press the “-” button and hold for
10 seconds.
Main unit
VOX
This changes the level at which
sound activates the transmit
throughout the system. In a noisy
environment, this may need to be
increased to a higher number.
Use + and – to change the setting.
The level selected will be heard
through the headset.
The options “OFF” and “OPEN”
should not be selected.
Main unit
MICROPHONE
Adaption to different
microphone types:
- Dynamic
- Electret
- Carbon
- Low impedance
For throat mics and sidewinder
headsets the Electret setting is
required. For most other headsets
Dynamic setting is required.
Main unit
General antenna
Units can be differentiated by
a coloured plastic ring
Black – Base/Portable with external input.
Red – Base Portable without external input.
Green - Portable
Antenna attachment connector makes it
possible to use different aerials such as
an external omnidirectional vehicle antenna
Main unit
There are three PTT buttons on the DECT
units. Most units supplied to site should be
paired and have Auto talk enabled, so the
PTT buttons will be locked out.
If Auto talk is NOT enabled, the PTT buttons
are used for choosing TALK or LISTEN mode
• A single press for listening
• A double press for to speak and listen.
PTT1 button is used for the
Standard DECT conference, (Group 1)
Main unit
Where units have not been sent
out in paired sets:
All Call (emergency call)
By pressing + and – buttons
simultaneously, it is possible to
send a short message, in simplex
mode, to all DECT-Com II units, if
their base units are synchronised
and in range of each other.
Main unit
External equipment; radios, telephones etc.
can be connected to suitable Base units.
Communication on the external extensions is
then selected by pressing PTT2 or PTT3
depending on programming. This is rarely
used.
Out of Range
 If the portable unit is close to the actual maximum working range from the
base unit, a voice message “SIGNAL LOW“ is given in the connected
headset.
 When the portable unit is out of range from the base unit, a voice
messages “SIGNAL LOW, OUT OF RANGE, OUT OF RANGE” is given
in the connected headset. After 20 seconds, the Portable will try to
find another base and a voice message “SEARCHING” is given.
 When the portable unit is returned within range again, or another base is
found, a voice message “BASE (number)” is given in the connected
headset.
 If Auto Talk Mode function is programmed (recommended), a portable
unit, after being out of range, always returns to TALK MODE as soon as
it is in range again.
For ease of use, it is recommended that:
 Units go to site already paired (paired units to be marked for example
KIT1 1A/1B, KIT2 2A/2B, KIT3 3A/3B etc).TANDEMS to be marked for
example KIT1 1A/1B/1C. This needs to be clearly marked and not
scratched in.
 Units to go to site with parameters pre-set (microphone type, VOX and
Volume).
 Pairing to be locked (to avoid complications caused by adding unit to a
base).
 Auto talk enabled (this eliminates the need to double click PTT1 on set up
and when unit returns to being in range having been out of range).
 Auto power off to be increased to 10 hours (out of the box setting is 4
hours).
 Base Selection option disabled (not required when a pairing is locked).
 Microphone type selection enabled (enables switching between throat mic
and headset).UNLESS ELETRET HEADS OR THROAT MICS are being
used.
 VOX level selection enabled (generally VOX 4 is adequate) unless using
MT701H03
5. Advanced Operations
Here we consider the following: Pairing a different Portable to a Base Unit assuming it was not done during the “out of the box”
configuration.
 Searching for a Base Unit from a Portable.
 Selecting a Different Base Unit from a Portable.
 Starting a Base as a Portable or returning it to a
Base.
Pairing a Portable with a Base.

MAKE A BASE UNIT READY FOR PORTABLES TO BE REGISTERED

Each Portable unit should be registered to a Base unit to be part of a DECT-Com
II conference.

With the Base unit in LISTEN-ONLY and VOLUME MODE, double press on the
[M] button to enter REGISTRATION MODE.

A Base unit in REGISTRATION MODE is indicated by a voice confirmation
“SUBSCRIPTION ON” and the LED flashing slowly.

Repeat with the Portable – put the unit in LISTEN-ONLY and VOLUME MODE,
double press on the [M] button to enter REGISTRATION MODE.

Both units will now start “Searching”. When complete, the Portable will confirm
with “Base (number), Group 1”.

IMPORTANT -When all portable units are registered to the Base unit, exit
REGISTRATION MODE by double pressing [M] button on the Base Unit.
Searching for a Base Unit from a Portable.
 With the Portable – put the unit in Base Selection Mode - LISTEN-ONLY
and VOLUME MODE. Then double press on the [M] button to enter
REGISTRATION MODE.
 A voice confirmation “SEARCHING” is given repeatedly, confirming
that the unit is searching for active bases in range.
 When a Base is found a voice confirmation “BASE (number), GROUP 1”
is given.
 To find more Bases, repeat this procedure again.
Selecting a Different Base Unit from a Portable.

In VOLUME MODE on a Portable unit in LISTEN MODE; double press on the [M]
button to enter BASE SELECTION MODE. A voice confirmation “BASE” is given,
urging it to select a Base.

Press [+] or [–] to cycle through the numbers of available Bases and an auto
setting. A voice confirmation is given for each available choice: “AUTO”, “ONE”,
“TWO” … Stop at your preferred Base number (or auto, see below).

Log on to the Base by pressing the [M] button and return to listen only menu
items by pressing briefly on the [M] button.

A voice confirmation “LOGIN” followed by “BASE (number), GROUP 1” is given,
confirming that the Portable unit is logged on to the Base with the given number as
a listener in the given group.

If “AUTO” is chosen, the unit will log on to the Base with the latest used Base or
the next available.
Starting a Base as a Portable or returning it to a Base.
 To start a Base as a Portable instead of a Base, switch on by
pressing both the “M” button and the “-” button at the same
time for 2 seconds. Remember to swap the colour coding ring
from black or red (depending on the type of Base used) to
green for Portable.
 To return it to it’s Base Specification, switch on by pressing
both the “M” and “+” buttons at the same time for 2 seconds
and revert the colour coding ring as required.
6. Advanced Programming
 The system has the capability for more advanced
programming combinations/scenarios.
 These require a suitable programming holder and software
and should be undertaken by experienced DECT II – com
Technicians.
Some typical scenarios for Advanced
Programming
 Setting Auto Talk for all Portables.
 Fixing Portables to specific Bases.
 One Base with Several Portables but with the conference split into
different groups. Each group can be contacted via PTT1, PTT2 or PTT3
 One Base with several Portables, with a Portable linked with a local radio
system.
 One Base with several Portables – Base linked via limo connector to PMR
radio.
 One Base with several Portables – Base linked via limo connector to
mobile phone.
 Two Bases linked via wire from headset connector.
 Two Bases linked via wire from limo connector.
 Two Bases with Portables moving between Bases.
Locked Buttons
 To avoid unwanted changes in the settings of functions, it is possible to
lock all buttons, so that only the ON/OFF function is active. This can be
combined with the automatic talk mode function for best results.
 A system for maximum 9 users, using only group 1, can be programmed
in a configuration where all the portables always should be in talk mode.
 Automatic talk mode makes it possible to ensure that all the members in
the small group are always in full conference mode, as soon as they are in
range of the base unit.
 Portables can also be “locked” to specific Bases units making it impossible
for them to be paired to other Bases.
7. Headset Options & Accessories
 Throat mics
 Ultra Lightweight Non Attenuating Headset
 Medium Attenuating Headset
 High Attenuating Headset
 Level Dependent Headset
 A Band
 B Band
 Helmet Mounted
Throat mic




Throat mics (model J-TTMO3/NP2/NB)
provide hygiene, noise reduction and
the wearing of protective glasses
advantages.
As the microphones are tight against
the user’s neck, only their voice is
heard and outside noise is virtually
eliminated.
As there is no boom mic’, the hygiene
issue with the boom mic’ is
eliminated. The invisi tube earpieces
should be personal issue.
For Network Rail, these are available
from High Motive through iprocurement
Ultra lightweight non attenuating headset –
MT701H03
3M™ Peltor™ Headsets
Available as a non-attenuation,
medium , high attenuation and level
dependant headset
The same J11 connector connects
any of these headsets to the Dect
Com II Portables/Base or Base
Extension units.
8. Hygiene & Maintenance
 Microphone Tape - used to wrap around the boom mic.
Removed after each wearer to prevent the spread of germs.
 Hygiene Kits – replacement cushions and liners for earmuff
type headsets. These should be replaced at least every 6
months.
 Cool Pads – self adhesive pads which stick to the earmuff
cushions to aid absorption of perspiration.
 Periodically wipe with an anti bacterial wipe as used for
cleaning a telephone.
 Periodic software and firmware upgrades may be required.
 For best results, certain functions should be locked out or
applied, such as Auto talk, eliminating the need to double
click PTT1 to join a conference.
 Batteries will need replacing after 500 charges. Installation is
simple. (Replacements will be available on the system to buy)
 Marking of each kit is highly recommended. Units should go
to site already paired (paired units to be marked KIT1 1A/1B,
KIT2 2A2/B,KIT3 3A/3B etc).TANDEMS to be marked kIT1
1/A1/B/1C (clearly marked and not scratched in).
