Coverage/Range
The maximum range depends on terrain condition and is obtained du-
ring use in an open space.
The only limitation to maximum possible range are environmental fac-
tors such as blockage caused by trees, buildings or other obstructions.
Inside a car or a metallic construction, the range can be reduced. Normal-
ly the coverage in the city, with buildings or other obstructions is about 1
or 2 Km. In open space but with obstructions like trees, leaves 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 than 12 Km.

Battery recharge
G18 is equipped for using a 7,4V Li-ion rechargeable battery pack, which
can be recharged by connecting the socket of the AC/DC wall adaptor to
a mains power socket and inserting the jack of the wall adaptor into the
desktop charger plug.
It takes 4 hours to fully recharge the radio.
The led of the desktop charger indicates the status of the recharge:
Red = charging,
Green = full charge
For maximum battery life, we recommend you to charge the battery pack
when the G18 is off and the battery pack is fully discharged.
! Using a different battery charger other than the one specified can
cause damage to your device or may even cause explosions and per-
sonal injuries.
The Battery power saving feature enables a reduction in consumption of up
to 50% and saves the battery life. If it has been set, it automatically activates
when the transceiver does not receive any signal for more than 5 seconds.
Power saving can be disabled only through the Programming software.

Operations
Power on/off and volume adjustment
Rotate the PWR/VOL clockwise to turn the radio on.
Rotate the control clockwise /counter-clockwise to adjust the volume le-
vel as you prefer.
To turn the radio off, rotate the control counter-clockwise till hearing a
mechanical “click”.
Transmission and reception
To communicate, all radios in your group must be set to the same chan-
nel.
Briefly press the Function key 1 to enable the Monitor feature in order
to make sure that the frequency is not busy, then press the PTT button.
For a maximum clarity, hold the device at a distance of about 4/10 cm.
Release the PTT key to receive.
Only one user at a time can talk during radio communications. Therefore, it is
important not to transmit when you are receiving a communication and use
the transmission mode sparingly to allow other users to talk.
Transmission consumes a significant amount of energy and should therefore
be used sparingly to prolong the battery life.
If you are unable to contact a station that you have no problems in receiving,
the station may be using CTCSS tones or DCS codes.
Monitor
The Monitor feature is for excluding (opening) the Squelch, in order to
listen to signals that are too weak to keep the Squelch permanently ope-
ned.
Press briefly the Function key 1 to enable such function.

12 | Midland G18 instruction guide
Roger Beep (end transmission tone)
When the PTT button is released, the radio will beep to confirm to other
users that you’ve finished your transmission and that they can start
talking.
Roger Beep is disabled by default and can be activated through the pro-
gramming software.
Alarm function (Emergency)
By pressing the Emergency button, the radio will switch to Alarm Emer-
gency mode.
G18 will switch to transmission for 30 seconds by generating a sound
alarm, then for further 30 seconds will remain in tx to allow the user to
communicate his status.
At the end, the radio will switch to reception.
If needed, the Emergency call can be repeated.

after about 5 seconds that you released the PTT, the scanning will be
active.
PRI (Priority Scan)
When you activate this function, the radio will alternately scan the stan-
dard channels and the priority one. The priority channel can be selected
only with the programming software. The default priority channel is CH1.
VOX
The VOX feature enables hands free conversations without using PTT:
just speak in the direction of the microphone and the communication
will be automatically activated.
The VOX sensitivity can be adjusted in 10 different levels (0,1,2,3…9)
through the Menu or programming software :
OFF means that the VOX is turned off, level 1 is set by default and has the
lowest VOX sensitivity, 9 is the highest one.
