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.

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
10 Advice for installation
to the CTE International technical office.
5.3.a Antenna
After verifying the efficiency of the external antenna, connect it to the
radio's Antenna socket (refer to par. 5.2) using a suitable connector.
5.3.b Power supply
Connect the red/black cable to a 12.6 VDC (+/- 10%) power source.
The red terminal connects to the positive; the black is negative and
must be grounded. It is important to verify that the power supply line
used is able to support 10 A of continuous current.
5.3.c Connection/Disconnection of the microphone
As previously mentioned, two types of microphones are available for
purchase separately:
• Standard microphone MK06/35 – microphone for general use,
with push to talk transmission button (PTT) (not supplied).
• Keypad microphone MK06/35-K – includes standard micropho-
ne functions, plus variable selective calling (if activated during pro-
gramming).
Standard microphone
To connect the microphone, insert the microphone's RJ plug into the
[3] Microphone socket on the front panel of the radio. To disconnect
the microphone, hold down the safety clip on the RJ plug and detach
it from the socket with caution.
Keypad microphone
The keypad microphone MK06/35-K can only be used if the radio has
been programmed for its activation, as per the following instructions.
If it has not been programmed, the command described below will
