Maintenance - Pipehorn Series 800-H User Manual

MAINTENANCE

The Pipehorn Series 800-H does not require periodic calibration or
any further internal adjustments. With reasonable care it should
give many years of trouble free service.
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 Receiver's vol-
ume is low, the Transmitter is producing a beeping tone, the opera-
tion distance decreases, or if the instrument becomes inoperative, it
is likely the result of dead batteries. You should install fresh batter-
ies as necessary. Change the batteries at least 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 com-
pleted. The Receiver times out after 5 minutes of no use, and the
Transmitter creates an audible tone letting the operator know it is
still turned on.
