BATTERY REPLACEMENT

The UH190 transmitter is powered by a standard alkaline 9 Volt battery. It is important that you use ONLY an ALKA-

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

They will provide only about 3 hours of operation. Similarly, nicad rechargeable batteries only give 3 hours of opera-

tion, and will also run down quite abruptly. Alkaline batteries provide about 7.5 hours of operation.

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

drawing. Only slight, 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. Insert the battery and close the cover by pressing in and across, reversing the opening procedure

outlined above. Note that the battery door will NOT close if the battery is inserted incorrectly, since the terminals will

hit a protective polarity barrier.
