1.5.4 Performance Monitor Notices
The performance monitor should be installed at around 10 cm from the radar.
• For open-array type radars, the performance monitor should be installed at the same
height as the antenna.
• For dome type radars, the performance monitor should be installed at the same height
as the radar.
1.6 Cable and Connection Considerations
• The cables may have been packaged without the locking rings installed. If so, you
should route the cables before you install the locking rings.
• After connecting a locking ring to a cable, make sure the ring is securely connected
and the O-ring is in place so the connection remains secure.
1.6.1 Power/NMEA 0183 Cable
• The wiring harness connects the device to power, NMEA 0183 devices, and a lamp or
a horn for visible or audible alerts.
• If it is necessary to extend the NMEA 0183 or alarm wires, you must use 22 AWG (.33
mm²) wire.

1.6.2 Connecting the Wiring Harness to Power
WARNING
When connecting the power cable, do not remove the in-line fuse holder. To prevent the
possibility of injury or product damage caused by fire or overheating, the appropriate
fuse must be in place as indicated in the product specifications. In addition, connecting
the power cable without the appropriate fuse in place voids the product warranty.
1 Route the wiring harness to the power source and to the device.
2 Connect the red wire to the positive (+) battery terminal, and connect the black wire to
the negative (-) battery terminal.
