Powering the transceiver:
Your FR-1538 radio transceiver operates on four AAA batteries. You may operate
your FR-1538 using the rechargeable batteries included or you may use alkaline
batteries. Alkaline batteries will provide slightly better performance than the
rechargeable batteries.
Installing the batteries:
To install batteries into the radio, it is necessary to remove the belt clip. To do this
you will need to release the spring clip securing the belt clip to the radio and lift the
belt clip away from the radio body. Next, remove the battery compartment cover by
sliding it downward towards the bottom of the transceiver. Observe the polarity
symbols on the top of the tray when inserting the batteries. Replace the cover.

The following guidelines will improve performance and provide longer operating
times for the FR-1538:
1. Do not mix old and new batteries.
2. The use of alkaline-type batteries is recommended to provide the longest
operating time.
3. Do not mix alkaline, standard (carbon-zinc) or rechargeable (Ni-MH) batteries.
4. If the unit is not to be used for an extended period of time, remove the batteries. Old
or leaking batteries can cause damage to the unit and will void the warranty.
Wrist Strap and Detachable Belt Clip Installation
The wrist strap and detachable belt clip are provided to enable you to carry the FR-1538
easily and safely. The wrist strap can be attached to the hole located on the top of
the belt clip. Feed the small loop on the end of the strap through the hole and then
pass the strap through the loop and pull tight.
The detachable belt clip fits into the slot located on the rear of the unit. To remove the
belt clip, press the locking clip at the top of the belt clip away from the unit and slide
the belt clip upwards. To install the belt clip, slide it down into the slot until it snaps

NOTESFORGOODCOMMUNICATION
1 . The FR-1538 14 channels are shared on a ‘take turns’ basis. This means
other groups may be talking on any of the channels. A common code of
ethics/courtesy is to switch to another vacant channel and not to attempt
totalk over someone who is already using the channel you first selected.
2. The FR-1538 has been designed to maximize performance and improve
transmission range in the field. To avoid interference, it is recommended
that you do not use the units closer than 5 feet apart.
3. For best transmission results, always keep your mouth about 2-3 inches
from the microphone (10) and speak slowly in a normal voice.

batteries and corroding the transceiver.
•Avoid exposing the transceiver to water or extremes of temperature.
•Do not use this device in or near a mining facility, which uses remotely trig-
gered explosives or in areas labeled “Blasting Area”. Premature or accidental
detonation may result.
•Do not attempt to modify or in any way increase the output of this transceiver. Its
output is designed to meet the legal limits set by the F.C.C.
•Do not use this device or change its batteries in potentially explosive
atmospheres as sparks in such areas could result in an explosion.
