BATTERY INSTALLATION
The transmitter is powered by a standard alkaline or lithium 9 Volt 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 adequate. Ni-cad rechargeable batteries will only provide 1.5 hours of operation, or less, and will run
down quite abruptly. Alkaline batteries provide over 4.5 hours of operation. Lithium batteries can be used to provide
up to 14 hours. Care should be taken not to leave a fully discharged lithium battery in the transmitter, as swelling of
the battery can make it difficult to remove from the compartment. 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.
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.
