BATTERY INSTALLATION

The transmitter is powered by a standard alkaline 9 Volt battery. It is important that you use ONLY an ALKALINE

battery for longest life. Standard zinc-carbon batteries marked "heavy-duty" or "long-lasting" are not adequate.

Ni-cad rechargeable batteries will only provide 2 hours of operation, or less, and will run down quite abruptly.

Alkaline batteries provide over 7 hours of operation on UHF versions and over 10 hours of operation on VHF

versions. The battery status circuitry is designed for the voltage drop over the life of alkaline batteries.

To open the battery compartment, press outward on the cover door in the direction of the arrow as shown in the

drawing. Only firm, sliding pressure is needed to open and close the battery door. Swing the door open and take

note of the polarity marked inside showing the location of the positive (+) and negative (-) terminals. You can see

the large and small contact holes inside the battery compartment with the door open.

closed.
