1.■ External Speaker and Programming Data Leads
• Connect an external speaker to Blue and Black Lead. Blue→Positive Elec-
trode (+), Black→Negative Electrode (-).
• Connect programming cable to Orange and Grey Lead.
2.■ NMEA/Out Leads
Through the rear panel lead, this radio can connect output GPS signals to
other devices.
•■Output Connection: Connect the output to the navigation device input line
(port) that supports NMEA0183 for receiving location data from other ships,
connect as follows: Brown→Sending Data, Data Output (-); White→Sending
Data, Data Output (+).
NOTE: The output signal of this radio complies with NMEA0183 version 2.0
or above, compatible with DSC, DSE navigation equipment, statement format
RMC, GSA, GSV.
3.■ External GPS Antenna
Connect to an external GPS antenna.
NOTE: Make sure that the GPS antenna is installed in an open, unobstructed
position so that the satellite signal can be received well. When installing the
GPS antenna, use the supplied double-sided tape to fix it.
4.■ Ground Terminal
Connect this terminal to a vessel ground to prevent electrical shocks and in-
terference from other equipment. Use a PH M3×6 mm screw (not supplied).
