BATTERY INSTALLATION

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

LITHIUM battery for longest life. Standard zinc-carbon batteries marked “heavy-duty” or “long-lasting” are not ad-

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

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.

Swing the

door open

Press outward on the

battery door in this

direction

Insert the battery correctly and close the cover by pressing the door closed and across, reversing the opening proce-

dure illustrated above. If the battery is inserted incorrectly, the door will not close. Do not force the door closed.
