BATTERY INSTALLATION
The transmitter is powered by a standard alkaline or lithium 9 Volt battery. It is important that you use ONLY ALKA-
LINE or LITHIUM batteries for reliable operation. Alkaline batteries will provide about 4 hours of operation while the
lithium batteries will operate the transmitter for over 14 hours. The battery status lamp will function normally only with
alkaline or lithium batteries. Standard zinc-carbon batteries marked “heavy duty” or “long-lasting” are not adequate.
They will provide only about 30 minutes of operation. Similarly, nicad rechargeable batteries only provide about 1 hour
of operation, and will run down quite abruptly.
The battery compartment is located in the lower section of the transmitter, between the two printed circuit boards. To
install a fresh battery, follow the steps illustrated below.
Look inside the battery compartment when the cover is off and take note of the two differently sized holes in the
battery contact pad. Insert the battery so that the large hole in the battery contact pad will line up with the large
contact on the battery when it is installed. The spring-loaded plunger in the bottom of the compartment (opposite the
contact pad) secures the battery in place.
The battery status is indicated by an LED on the bottom panel. The LED will glow brightly when the battery is good and
will dim as the battery condition deteriorates. The LED is green with a new battery. The battery status is also displayed
on the Information Display on the front panel of the receiver. See the receiver manual for further details.
Note: It is possible to insert the battery backwards and still be able to close the battery door. No damage will occur but
the transmitter will not operate in this condition.
