Coverage
The maximum range depends on terrain condition and
is obtained during use in an open space.
The only limitation to maximum possible range are en-
vironmental factors such as blockage caused by trees,
buildings, or other obstructions. Inside a car or a metallic
constructions, the range can be reduced. Normally the
coverage in the city, with buidings or other obstructions
is about 1 or 2 Km. In open space but with obstructions
like trees, leafs or houses the maximum possible range
is about 4-6 Km. In open space, without obstructions
and in sight, like for example in mountain, the coverage
can be more that 10 Km.
Battery and battery compartment
The transceiver accepts the rechargeable battery pack
(included only in the M48 Plus and M99 Plus models)
or 4AAA alkaline/ rechargeable batteries. To open the
battery compartment, hold the unit face down and un-
hook the battery holder in the lower part of the radio and
gently slide the cover.
Attention: the battery pack provided with the M48 Plus
and M99 Plus models, must be recharged before the
rst use (see the section “Recharging” for more info).

› CTCSS-sub-tone setting
The CTCSS sub-tones, are code numbers (from 1 to 38) to be added to the rst
8 channels in order to create a new private channel. You can add up to 38 codes
to the channels named from P1 to P8, that means you can create up to 308 new
channels. For example if you add the CTCSS sub-tone “27” to the channel “P3”
you will obtain the new channel “P327” that will be able to communicate to other
transceivers only if they will be set on the same channel and sub tone.
To activate 38 different CTCSS sub-tones follow these steps:
1. Turn on the radio.
2. Press the “Menu” button and select with the p/q buttons one of the 8 channels
(from P1 to P8).
3. Press twice the “menu” button until the display shows the selected channel with
the ashing two digits CTCSS sub-tone (on the right of the channel)
4. Select with the p/q buttons the desired CTCSS sub-tone (from 1 to 38).
5. To conrm the setting press PTT.
Now the radio transmits and receives using the programmed CTCSS sub-tone. If
you don’t want to use any CTCSS tone, select “00”.
Show the CTCSS-sub-tone on the LCD
When you activate a CTCSS sub-tone, from P1 to P8, the tone is visible just on the
right side of the channel. For the other channels (from 9 up) the CTCSS sub-code is
pre-programmed and then “hidden”. To temporary show a pre-programmed channel
and his CTCSS sub-tone, press the “menu” button for more than 3 seconds.
