and replace the battery cover.
Range
The PMR wristwatch is intended for indoor and outdoor use. However please note they
can be damaged by water/liquid ingress, impact or other careless treatment.
In a densely populated area, house, apartment, etc. the radio waves transmitting the
signal may be hindered reducing the range. The maximum operating range requires
unobstructed line of sight transmission with the antenna raised and will be up to 3
kilometre.
Charging
The display will show when it is time to recharge battery. The indicator has three
segments, which disappear as the battery charge decreases, when the battery is running
low a warning tone will be heard, the operating range and signal quality will deteriorate.
Charge the PMR wristwatch as soon as possible under these conditions!
Connect the electrical adapter to the socket marked M/S CH. The battery indicator will
stop ashing when charging is complete (approximately 14 hours), fully charged batteries
will last for approximately 40 hours in standby or 2 hours’ talk time. These operation
times apply at normal ambient temperature.

succession.
Please note!
If you are unable to communicate it may be because different channel or transfer codes have been selected,
the battery is running low, the antenna has not been raised on the PMR wristwatch, or the units are too
far apart or are obstructed.
Channel selection
All PMR and CB equipment share the same available operating channels. If the channel

Voice control (VOX)
This unit can be used without having to press the PTT button to transmit. By setting
the correct level, the equipment can automatically determine whether you are speaking
or not.
Test different settings until the sensitivity selected is acceptable. Please note however
accurate your setting there is always a small risk that increased noise from your
surroundings may activate the transmitter, and may result in the initial word being
unclear. A simply remedy would be to announce the name of the person being contacted
before talking.

VOX will be displayed while this function is active. If the unit transmits by itself the
sensitivity will be set too high, press 1 to temporarily interrupt the call and change this
