Modifying the RainAlert II Monitor to Support
an External Antenna
Modifying the monitor to support an external antenna involves
disconnecting the internal antenna and rerouting the internal antenna
connector to the TELCO/EXT ANTENNA port. Perform these
modifications and connect the external antenna to the monitor in the
following way:
Note: Disconnect power to the monitor before performing
any modifications. In addition, to prevent damage to the
cable, do not kink or bend the antenna cable when coiling.
1. Undo the latches to the door on the monitor enclosure, and
open the door.
Note: Opening the door to the monitor enclosure to
connect the external antenna increases the risk of damaging
or introducing debris or moisture to the circuit board.
Make every effort to prevent water, dirt, and debris from
contacting the monitor's circuit board when opening or
working within the enclosure.
2. Disconnect the battery pack’s cable from the printed circuit
board’s power cable.
3. Disconnect the internal antenna’s cable connector from the
printed circuit board’s cable connector. This connection exists
to the right of the printed circuit board.
