Connect power
The Broadband radar can operate on 12 or 24 V DC systems. The Broadband radar requires a
+V DC to be applied on the yellow power on wire in order to operate. This can be achieved in
one of three ways.
• Common the red and yellow wire together. Radar will power on when power is applied
• Use ignition or install a switch that will provide power to the yellow wire. (It is
recommended to use a 5 amp fuse or breaker). The radar will turn on when switch is
activated
• Connect the yellow wire to external wake up of suitable display. Radar will turn on when
display is turned on
Before connecting power to the system:
• Make sure the scanner has been installed and is secured.
• Make sure the scanner interconnection cable is connected to the scanner.
• If using the Radar Interface Box make sure all connections have been made to the
display.
For systems using a radar interface box
• Connect the red wire to power positive 12 or 24 V DC. Use a 5 amp fuse or breaker.
• Connect the yellow wire to power source that will turn on the system (see above).
• Connect black to power negative.
For systems not using radar interface box (Lowrance HDS USA only)
• Connect the red wire to power positive 12 or 24 V DC. Use a 5 Amp fuse.
• Connect the yellow wire to power source that will turn on the system (see above).
• Connect black to power negative.
