Batteries

The Receiver and Transmitter contains alkaline batteries for

their power source and you should change them periodically.

How often the instrument is used determines battery life. If the

sound becomes weak, the operation distance decreases, or if

the instrument becomes inoperative, it is likely the result of dead

batteries. You should install fresh batteries as necessary.

Change the batteries once every six months to be certain that

the instrument will be ready to operate when needed.

NOTE: The usual reason for an inoperative unit is that the

power switch was not returned to the OFF position when work

was completed. The receiver times out after 5 minutes of no

use, and the transmitter creates an audible tone letting the op-

erator know it is still turned on.

The Pipehorn Series 800-HL was carefully calibrated at the fac-

tory and no further internal adjustments should be required.

With reasonable care it should give many years of trouble free

service.
