GPS ANTENNA
!
The WatchMate requires a GPS fix before it can transmit its position.
Internal
The WatchMate has a built-in GPS antenna.
• This antenna requires an unobstructed
view of the sky.
• The antenna performance may be
significantly reduced if the WatchMate
is installed on, under, or near large
metal structures.
• The antenna faces upwards and is
located as shown:
• For faster fix times, turn the unit off using
the menu option and keep power
connected to the unit.
HINT:
Use the My Position screen to view
satellite signal strengths which will assist
in determining the best location for the
WatchMate or the external GPS antenna.
External (optional)
If you are mounting the WatchMate in a location which will not
provide adequate GPS signal coverage, then you must install
a dedicated GPS antenna.
• The GPS antenna should be situated so that it has an unobstructed
view of the sky above.
• Do not place the GPS antenna near or in the path of radar
or HF antennas.
• The antenna cable is terminated with a small SMA connector to
facilitate easy routing through holes and openings. Do not cut the
cable unless you have the proper tools to crimp a new connector.
Make the connection to your AIS transponder last after antenna
installation is complete.
CAUTION:
The Vesper Marine GPS antenna is designed specifically
for use with the WatchMate Transponder. Performance cannot be
assured unless you use a Vesper Marine GPS antenna. Use of
a different antenna may damage the device and void your warranty.
