Coverage (referred to PMR frequency band)
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 factors
such as blockage caused by trees, buildings, or other obstructions. Insi-
de 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 than 12 Km.

Above all….Safety!
Warnings
! Do not open the radio for any reason! The radios precision mechanics
and electronics require experience and specialized equipment; for the
same reason, the radio should under no circumstances be realigned as
it has already been calibrated for maximum performance. Unauthori-
zed opening of the transceiver will void the warranty.
! Do not use detergents, alcohol, solvents, or abrasives to clean the
equipment. Just use a soft, clean cloth. If the radio is very dirty, slightly
dampen the cloth with a mixture of water and a neutral soap.
BATTERIES
! Do not try to charge alkaline batteries or non rechargeable batteries.
Make sure that when you charge the radio, only rechargeable NI-MH
batteries should be contained in the battery compartment! It is very
dangerous attempting to recharge other types of batteries (for exam-
ple alkaline or manganese batteries). Batteries which are not suitable
to be recharged may leak, explode or even burn and cause damage!
! 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.
! Do not throw batteries into fire or place them near heat as this may
cause explosions or personal injuries. Dispose of the batteries accor-
ding to procedures set out by local regulations.
! Do not mix old and new batteries or batteries of different types or bat-
teries which have been used in different manners.

Preparing the transceiver
The radio can be recharged with different type of batteries: here below
the possibilities.
Note: To optimize the recharge process, we suggest you switch off the radio
to recharge it.
Recharging the NIMH batteries (4 x AA)
Place your transceiver into the cradle of the desktop charger or connect
the MW904 wall adaptor to the proper jack of the radio.
This type of batteries is recharged with a constant current, either you use
a desktop charger or MW904; therefore the recharge time depends from
the recharge status and from the batteries capacity.
Theres no evidence when the recharge is finished, therefore we suggest
you detach the wall adaptor from the radio or remove G7 Pro from the
desktop charger cradle once the recharge is complete.
Here below some information about the recharge time (indicative) for
some batteries of different capacity:
Battery capacity mAh Approx. recharge time (hours)
1200 5
1800 7
2100 8
When the radio is in the charger cradle, the processor makes a sort of che-
cking on the battery; the led on the charger will light up for 10 seconds,
then will turn off and the recharge will start.
The battery icon on the radios display will be blinking for all the rechar-
ging process, as well as the red led will be lighting up on the desktop char-
ger.
Midland G7 Pro user’s manual | 11
Recharging the NIMH battery pack PB-ATL/G7 800 mAh
Place your transceiver into the cradle of the desktop charger or connect
the MW904 wall adaptor to the proper jack of the radio.
This type of batteries is recharged with a constant current, either you use
a desktop charger or MW904, therefore a complete recharge takes about
5 hours.
Theres no evidence when the recharge is finished, therefore we suggest
you detach the wall adaptor from the radio or remove G7 Pro from the
desktop charger cradle after 5 hours.
When the radio is in the charger cradle, the processor makes a sort of che-
cking on the battery; the led on the charger will light up for 10 seconds,
then will turn off and the recharge will start; the battery icon on the ra-
dios display will be blinking for all the recharging process, as well as the
red led will be lighting up on the desktop charger.
Recharging the Li-Ion battery pack ‘PB-PRO’
(optional)
Place your transceiver into the cradle of the desktop charger or connect
the MW904 wall adaptor to the proper jack of the radio.
The recharge of the Li-Ion battery pack is managed by a radio processor
and the battery status can be checked by the icon on the display and by
the led on the desktop charger
The recharge status is indicated by the led on the desktop charger and
by the battery icon blinking on the display of the radio;
When the recharge is complete, the led will turn off and the battery
icon on the display will be full of bars and fix.
When the radio is in the charger cradle, the processor makes a sort of che-
cking on the battery status: in this step, the led on the desktop charger will
light up for 10 seconds, then will turn off and the recharge will start.
To optimize the recharge of the Li-Ion battery pack, in the final phase the
processor will alternately charge and pause for almost one minute (the
led will turn off).
If the radio is placed in the desktop charger switched on, when the rechar-
ge is complete the led will blink.

Memory effect of rechargeable batteries
Rechargeable NiMH (Nickel-Metal-Hydrate) batteries are affected by
what is known as the memory effect”. This phenomenon is associated
with a drastic reduction of battery autonomy and is triggered if the bat-
teries are regularly charged before being fully discharged and/or are not
completely recharged. To avoid the memory effect:
When possible, recharge the batteries only when they are completely
discharged (until the device turns itself off during normal use)
Do not disconnect the battery charger before the time indicated for a
full battery charge.
The memory effect should not be confused with the normal battery life,
which is 300-400 cycles of charge/discharge on average. It is completely
normal for operating duty to decrease when the batteries have reached
the end of their life; at this point, you will need to substitute the batteries.
Installing and removing the belt clip
With the belt clip you can easily attach
the transceiver to your belt. The clip
however, must be removed in order to
install or change the batteries. To remo-
ve the belt clip follow the indication of
picture 1. To fix the clip back to the devi-
ce slot it in the guides at the back of the
transceiver until it clicks into place.

Basic operation
Turning on/off
To turn on the transceiver, turn the VOLUME knob clockwise until you
hear it clicks: the LCD display will light up and do an Auto-Test. Subse-
quently you will hear 2 beeps of different tones.
To turn off the transceiver, turn the knob counter-clockwise until you
hear another click.
Volume control
Turn the knob VOLUME to about half way and adjust it to a comfortable
level as soon as you receive a signal. If you do not receive a signal you can
use the button MON/SCAN described in par. “MON button.
Transmission and reception
The PTT key has a dual function, as it is composed by 2 parts: a bigger PTT
and a red one, smaller, identified with “boost”.
When you press the bigger PTT the transceiver transmits with high or low
power (depending on the setting of the MENU: H or L); while the smaller
PTT (Boost) always transmits with high power.
To transmit:
1. Make sure that no one else is currently talking on the selected chan-
nel;
2. Keep button PTT firmly pressed: TX will appear on the display;
3. Before you start talking wait for a fraction of a second then speak
normally, in the direction of the microphone, and hold the device at
a distance of about 5 cm.
4. When you have finished, release the PTT: TX will disappear from the
display;
5. When the radio is in reception mode (PTT not pressed) you will auto-
matically receive any communication (RX displayed).
During transmission and reception try, as far as possible, to keep the an-
tenna in vertical position and to avoid obstacles towards the direction of
the other party.
Midland G7 Pro user’s manual | 15
MON button (Monitor)
The Monitor button is for temporarily excluding (opening) the squelch,
in order to listen to signals that are too weak to keep the squelch per-
manently opened. By excluding the squelch you will avoid listening the
communication chopped by the squelch. In order to activate the Mo-
nitor function, so as to listen to all traffic on the selected channel, keep
pressed the MON/SCAN button for about 2 seconds. Keep pressed the
button MON/SCAN for about 2 seconds to disable this function.
Scanning all channels
Midland G7/G7E Pro can automatically search for signals throughout the
PMR/LPD bands by scanning, i.e. selecting the channels in rapid sequen-
ce. When a signal is detected, the scanning pauses on that channel and
you can transmit by pushing PTT . If you press PTT during scanning you
can transmit on the channel from which the scanning started. The scroll
buttons / allow you to change the direction of scanning (from lower
channels to higher ones or vice versa) and therefore to skip communica-
tions which are of no interest.
Press briefly the button MON/SCAN to start scanning.
If you want to stop it, press again MON/SCAN. Your transceiver will go
back to the channel from which the scanning originally started.
Display backlight
If there is insufficient light to read the display you can press the MENU
button to switch the display back light on for about 5 seconds.
Switching the backlight on the display adds an additional drain on the
batteries. Try to make a moderate use of this.
5.7 Keypad lock
Keep pressed CALL/ for about 5 seconds and will be displayed as con-
firmation. Only PTT and CALL/ remain active. To disable this function,
keep pressed again CALL/ for 5 seconds approx.
16 | Midland G7 Pro user’s manual
Power Save
The battery power saving feature enables a reduction in the consumption
of up to 50%; power saving comes on automatically when the transceiver
does not receive any signal for more than 5 seconds. When the batteries
are discharged, bt LO appears on the display: replace the batteries or re-
charge the battery pack.
