Thanks for choosing Midland! G10 is a portable transceiver that is free use in
almost all European countries. For further information, we suggest you look
at the “Restrictions on the use” chart.
Midland G10 is a multi-task PMR446 transceiver.
Combining the latest technology in radio communication along with a
sturdy mechanical frame, G10 is the ideal and effective solution for the
professionals who need to stay in touch with the working team (in con-
struction sites, buildings, shows, trade fairs or hotels) or for leisure users
that just want to keep up with friends and family.
Programming software (optional)
Thanks to Midland Programming software PRG10, it is possible to incre-
ase the performance of your radio or to reduce its functionality by disa-
bling some of the default features (CTCSS, TOT...)
For further information, please consult the Programming software ma-
nual.
Any attempt to change frequencies or output power of the radio invali-
dates the approval.

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. In-
side a car or a metallic constructions, the range can be reduced. Normally
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.

Operations
Power on/off and volume adjustment
Rotate the Power/Volume knob 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
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.
Hold down the Function key 1 to enable such function.
Scan
This function can be activated only by means of the optional program-

Midland G10 instruction guide | 7
ming software.
To enable the Scan function, all 16 channels must be programmed.
If you turn on the radio on channel 16, the scanning will automatically
start.
Whenever any signal is detected, the scanning will stop on a busy chan-
nel.
If the PTT is pressed, you will transmit on the latest busy channel.
Channel 16 is the priority channel, therefore if you don’t pick up any
signal when you press PTT, the radio will transmit on channel 16.
Squelch
The Squelch function suppresses noises on free channels and allows to
receive even weak signals.
G10 has 10 different Squelch levels that can be set by programming sof-
tware: 0 means that the Squelch is turned off; from level 1 to level 9 you
will have different levels of noise reduction. The higher is the level, the
louder will be the Squelch.
By default, the Squelch level of G10 is set on level 4.
Make sure you do not set an excessively high squelch level because in this
case you may not be able to receive weaker signals. On the other hand an
excessively low Squelch value could enable the Squelch even when no si-
gnals are present.
Squelch must always be adjusted when no signals are present.
The Time Out timer is settable from 30 sec to 270 sec. only through the
programming software.
This feature is disabled by default.
Battery recharge
G10 is equipped for using a 7,4V Li-ion rechargeable battery pack which
can be recharged 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 4-5 hours to fully recharge the radio.
For maximum battery life, we recommend charging the battery pack
when the G10 is off and the battery pack is fully discharged.

! Using a different battery charger other than the one specified can cau-
se damage to your device or may even cause explosions and personal
injuries.
The Battery power saving feature enables a reduction in consumption of
up to 50%. If it has been set, it automatically activates when the transcei-
ver does not receive any signal for more than 5 seconds in order to save
the battery life. Power saving can be disabled only through Programming
software.
Maintenance
Your G10 was designed to fulfill any warranty obligations and to enjoy
this product for many years.
As for all the electronically devices, we recommend you to follow this few
suggestions:
• Do not attempt to open the unit. Non-expert handling of the unit may
damage it and/or annul the warranty.
• When using regulated power supply, take notice of power voltage,
that must be between 6V and 8V to avoid damages.
• High temperatures can shorten the life of electronic devices, and warp
or melt certain plastics. Do not store the radio in dusty or dirty areas.
• Keep the Radio dry. Rainwater or damp will corrode electronic circuits.
• If it appears that the Radio diffuses peculiar smell or smoke, please
shut off its power immediately and take off the charger or battery
from the Radio.
• Do not transmit without antenna.
