Installation Considerations
When installing the wireless remote system: 1) Mount the receiver
box and antenna away from sources of electronic interference
such as the autopilot hydraulic pump and the engines ignition
systems. 2) Mount the antenna in free space and in a direct line
of sight to where the keypad transmitter is expected to be used.
Do not mount the antenna in a corner or behind a bulkhead that may
reflect or absorb the radio signal from the remote.
Choose the locations for mounting the receiver and antenna such that
the cable lengths allow for proper connections. You may want to
temporarily mount the components with tape or tie-wraps and try out
system operation before hard mounting any parts.
Installation
1. Mount the receiver box. (Mount the unit away from possible
electronic interferance, such as the Electrohydraulic Unit.) Use the
screws provided, or use wire ties to mount.
2. Mount the antenna using the screws provided.(See Installation
Considerations above.)
3. Unplug the wired remote from the ECU wire #3, and plug in the
wire coming from the receiver box unit. See Fig.1 and Fig.2
