Note A MAIN shut-off time during system non-operation can be set from 0~30 minutes via external programmer;
manufacture preset at five (5) minutes. To resume operation after five minutes, just press any pushbutton to
reactivate the receiver MAIN.
Note B: If transmitter lo w voltage occurs during operation, other than transmitter itself will display visual warnings, it
will also send out a low voltage signal to the receiver to activate its external low voltage warning device. By
connecting a horn, buzzer, or siren to the LV-relay output will ensure that the operator will clearly notice the
low voltage warning even in hard to see or hear environments. After one minute of low voltage warning, to
insure maximum safety, both the transmitter power and the receiver MAIN will be deactivated.
For proper battery replacement, you must first turn “off” the transmitter power, replace the batteries, and then
turn the power switch back “on” again to reactivate the transmitter and the receiver unit.
