hable front panel can be installed on the dashboard, using the proper

optional kit.

For separation and mounting of the front panel, refer to the instruc­t

ions found in the kit.

5.1.c Hand-held microphone mount

The mount provided (mod. R14053) is to be used as a storage place
for the microphone when the radio is inactive.
An option available to the user is the monitor function (hang-up), whi­c

h is automatically activated when the microphone is removed from
its mount.
For further details regarding the monitor function, refer to par. 6.6.

Microphone installation:

1) Fix the bracket in a position close to the front panel of the radio

and near to the radio operator.

2) If you wish to activate the monitor function when removing the mi-

c

rophone from its bracket (hang-up), connect this to the negative

(ground) of the vehicle.

Place the bracket in a location which makes the micropho­ne cable not taut and avoid that possible rocking of the mi­c

rophone could cause it hitting the vehicle’s parts or sur-

r

ounding objects and get damaged. As well, avoid placing

the microphone in a location where surrounding objects may

Advice for installation

cause accidental activation of the push to talk (PTT) button
and therefore transmission.

Neither the standard (MK06/35) nor the keyboard (MK06/35-K)

microphones are supplied with the radio; however, installation of
the mount is the same for both. For further details, refer to par.

4.1.b.

5.2 Installation of the vehicular antenna

Install the antenna on the exterior of the vehicle. Installation must be
in conformity with the regulations of the antenna manufacturer, and
according to the instructions included with the antenna. Installation
must also be in conformity with general security and local regulations,
as well as with those indicated in Chapt. 2.
Contact your vendor for advice on choosing the best antenna for your
needs. The antenna must be able to irradiate at least the nominal
power of the radio. Once installed and calibrated, the antenna must
have a SWR (Standing Wave Ratio) as low as possible and at below
1:1.5. SWR should be measured with a suitable instrument once the
antenna is completely installed in an open space.

When used in a vehicle, the radio offers optimal performance

when the antenna is installed at the centre of the roof, in a vertical
position that is free of obstacles.

5.3 Connections

A faulty connection (or connection with an unapproved devi-

ce) can seriously damage the transceiver, as well as people or
objects. For further details, refer to the service manual and/or

Basic operations

6 BASIC OPERATIONS

IMPORTANT! One or more functions among those described
from this point onwards can be rendered inactive by your radio
network administrator, and depending on the radio’s program­m

ing. For this reason, you may find you are not able to access
one or more of the functions, or that some functions may differ
from the below descriptions.
Furthermore, it is possible that one or more functions can be
activated via the function keys F1, F2, F3 or F4/ESC, rather than
via the normal command menu. In this situation, you will see
the (abbreviated) function written directly above the button to
which the function has been assigned (in other words, on the
bottom part of the display).
For further details or when in doubt, contact your vendor/ra­d

io network administrator. For information regarding the use of

menu commands and function keys, refer to Chapt. 7.

ation transmitted on the selected channel and volume.

• CTCSS/DCS - if programmed, allows the user to listen only to
communication coming from other members of the network with
the same CTCSS/DCS tone/code. For further details, refer to
Chapt. 9.

• Selective call - allows the user to send and receive calls from a
user or group.

When you receive a valid selective call, the status LED will flash oran­g

e and an audio signal will alert you to the incoming call. For further

details, refer to Chapt. 9.

CTCSS/DCS and Selective Call may be combined together.

CTCSS/DCS and Selective call allow for sharing of the same
frequency on multiple radio networks.

rophone.

5) Release the PTT at the end of the call, ensuring the status LED is
no longer lit.

6) At the end of the conversation, hang the microphone back up on

English

14

Basic operations

its mount.

Begin speaking only after having pressed the PTT button and do

not release it until you have finished speaking, otherwise all or
part of your message will not be transmitted.

Do not yell! This does not increase the distance of transmission;

rather, your words come across as distorted.

Normally, a transceiver will not allow you to send and receive

simultaneously, so when you are speaking, others will not be able
to do so. Send your message within a reasonable time period so
as not to occupy the channel for very long.

Consult the following paragraphs for information on correct

transmission.

6

.7.a Time Out Timer (TOT)

The radio can be programmed with an internal TOT (Time Out Timer),
which automatically forces your radio into reception mode if you have
been speaking for too long (time for this is determined in the program­m

ing phase). If this happens, release the transmission button and
wait for a few seconds: the transmission functions of the radio will be
automatically restored. For further information, contact your vendor
or network administrator.

6.7.b Busy Channel Lock Out (BCLO)

Activation of this function impedes the use of the PTT button when
the channel is busy.
Depending on the programming, the BCLO can act when it picks up
any signal, or when a signal is coming from a specific CTCSS/DCS

signal.

This setting is not available by the end user. For further details,
please contact your radio network administrator.

6.7.c Selecting transmission power

Use with CTCSS/DCS and/or Selective call

9 USE WITH CTCSS/DCS AND/OR SELECTIVE CALLS

9.1 Reception

In this operating mode, your radio is programmed so that the audio is
activated only when receiving a correct CTCSS/DCS and/or selective
call signal.
The audio will thus remain silent until you receive a correct CTCSS
tone, a correct DCS code, and/or a valid selective call.

• If a correct CTCSS/DCS signal is received, the status LED will

light up in orange for the duration of signal reception, and the
icon will appear on the display

.

• If a valid selective calling signal is received, the status LED will
flash orange and the

icon will appear on the display.

If a signal is received but does not contain the correct tone/code, the
audio will remain deactivated and the LED will appear green.

Depending on the radio’s programming, it may be possible to
temporarily deactivate CTCSS/DCS and Selective call to monitor
radio traffic (monitor function). For further details, refer to par.

6.6.

9.2 Transmission

9.2.a CTCSS/DCS Transmission

If your transceiver has been programmed to transmit a CTCSS tone
or a DCS code, you don’t have to do anything. The CTCSS tone or
DCS code are automatically sent each time you transmit (the device
will not show this status).

9.2.b Sending a selective call

Depending on the programming, your transceiver may be able to send
up to four selective calls:

• Call 1 – first selective call (fixed)

• Call 2 – second selective call (fixed)

• User – variable selective call; the variable digits can be keyed into
the MK06/35-K keypad microphone (refer to. par. 4.1.b).

• Emergency – selective call for emergencies (special call sent re­p

eatedly, and defined during the programming phase).

Rapid send of selective calls

Your transceiver can be programmed to send certain selective calls
using one or more of the F1, F2, F3 and F4/ESC function keys or
using the command menu. Also, the Emergency selective call can
be activated via a suitable contact on the rear Input/Output socket.
For further details, refer to Chapt. 13.

To emit a fixed selective call using the function keys:

1) Ensure the channel is unoccupied by checking that the status
LED is off (or flashing orange).

2

) Press the F1, F2, F3 or F4/ESC key that corresponds to the call

you wish to send. The call will be sent automatically, the status
LED will be lit in red, and the display will simultaneously show the
selective address corresponding to the button pressed.

When you follow the operation outlined in step 2, the device will
automatically go into transmission mode (status LED lit in red);
therefore, you do not need to press the PTT transmission button
on the hand-held microphone.

10 ADVANCED FUNCTIONS

10.1 Channel scanning

This function is particularly helpful when multiple channels have been
programmed. It allows you to follow radio traffic, as well as to re­s

pond to calls from different channels. When the radio picks up a
valid signal during scanning, it pauses on that channel and commu­n

ication is heard on the speaker. When the signal ends, scanning
begins again automatically.
If CTCSS/DCS or selective calls have been previously programmed,
the device can be programmed to pause only at incoming signals
containing the appropriate signals.
