If the monitor function has been activated (hang-up), you will activate it each time you remove the microphone from
its mount.

4) Speak in a normal voice approximately 5 – 10cm from the microphone.

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 (T ime 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 programming phase). If
this happens, release the transmission button and wait for a few seconds: the transm ission fun cti ons of the radio will
be automatically restored. For further information, contact your vendor or network administrator.

8 CUSTOMIZATION
This section describes the settings that regulate various paramet ers, depending on environment and specific use of
the radio; for example, display contrast, backlighting, etc.
8.1 Adjustment of microphone sensitivity
Normally, the sensitivity of the microphone allows the user to speak at a distance of up t o 10 centimeters from the
microphone. However, if the surroundings or the vehicle in which you are working is particularly noisy, you can
reduce the sensitivity of the microphone so as to avoid trans mitting your surrounding noises to others. When the
sensitivity is decreased, you need to speak closer to the microphone and/or with a louder voice, but your message
will still be heard clearly. To adjust the microphone sensitivity:
1) Press the menu/↵ button to access the command menu, then use the buttons to highlight the

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 correc t tone/code, t he 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 CT CSS 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.

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 respond to calls from different channels. When the radio picks up a valid signal during
scanning, it pauses on that channel and communicati on is heard on the speaker. When the signal ends, s canning
begins again automatically.
If CTCSS/DCS or selective calls have been previously programmed, the device can be programmed to paus e only
at incoming signals containing the appropriate signals.

If you try to activate scanning using an empty scanning list, an error sound will be emitted and scanning will not start.
Obviously, the list of scanning channels must include at least two channels.
If you press the PTT transmission button during channel scanning, the radio will pause on a predetermined channel, chosen
during the programming phase (this will be the priority channel or another predefined one), and will begin transmission. When
you release the PTT, the scanning will begin again automatically.
To stop the scanning, repeat the above procedure (at step 4, remove the ).
