2. Slide the cover down and then lift cover at bottom to open. Remove cover.
3.Insert four AAA batteries (positive (+) end toward the bottom begining at left side and
alternating positive terminals as shown),or insert the rechargeable batteries.
The following guidelines will improve performance and provide longer
operating times for the GMRS-1100:
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 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.

to switch to another vacant channel and not to attempt to talk over someone who is
already using the channel you first selected.
2.The GMRS-1100 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 (9) and speak slowly in a normal voice.
4.To increase battery life, avoid features such as Scan, Dual Watch and Weather Alert.
These features will reduce operating time considerably.
