Installation
Mounting the GPS 128
The GPS128’s compact case is suitable for mounting
in exposed locations or at the nav station. The unit
comes with a gimbal mount that can be used for sur-
face, overhead, or flush mounting the unit. When
choosing a location for the display unit, make sure you
consider the following conditions:
• There should be at least 2” (5 cm) clearance
behind the case to allow connection of the
power/data cable.
• The mounting surface should be rigid enough to
support the unit and protect it from excessive
vibration and shock.
To surface mount the GPS 128:
1. Place the mounting bracket in the desired location.
2. Mark and drill the four mounting holes for the fasten-
ers you are using (not included).
3. Fasten the bracket to the surface using the appropri-
ate fasteners.
4. Insert the GPS 128 into the mounting bracket.
5. Screw the two mounting knobs through the bracket
and into the GPS 128.
6. Connect the power/data cable and antenna to the
back of the unit, making sure the locking rings are
engaged.
