system maintenance
The system requires no specific maintenance other than battery
replacement for the remotes.
LCD 2-Way Remote Battery Replacement
The 2-way remote is powered by a 1.5V AAA battery. The
Battery Level indicator has three level indicators that serve as a
visual indication of battery charge. When the battery reaches a
low charge level that requires replacement, the transceiver will
generate a single notification chirp, and the Battery Level indi-
cator will flash continuously.
To replace the battery, gently pull the battery cover release tab, then
slide the door down to expose the battery and remove the expired
battery. Place the new battery into the transceiver observing the
correct polarity. When power is returned the transceiver will light
all icons in the LCD and generate all beeper tones once.
4-Button Remote Battery Replacement
Your remote is powered by a small, lightweight 3-volt lithium
battery (CR2032) that will last approximately one year under
normal use. When the battery begins to weaken, operating range
will be reduced and the LED on the remote will dim.
