Mounting the GPSMAP 135 Sounder Unit
The GPSMAP 135 Sounder’s compact, waterproof case is suitable for mounting
in exposed locations or at the nav station. The unit comes with a gimbal bracket
that can be used for surface or overhead mounting. When choosing a location for
the display unit, make sure you consider the following conditions:
• There should be at least a 3” (5 cm) clearance behind the case to allow connection of the
antenna, power/data cables, and ferrite clamps.
• The unit should not be mounted where it is exposed to excessive temperatures for
extended periods (see page 84).
• You should provide adequate clearance for the G-chart cartridge cover to swing open
freely. You may have to swivel the unit to get a firm grip on the cartridge.
• The mounting surface should be heavy enough to support the unit and protect it from
excessive vibration and shock.
• For flush mounting, make sure the flat panel is between 0.08” and 0.30” (2 to 7.7mm)
thick to use the cam lobe built into the mounting bracket.
To install the GPSMAP 135 Sounder unit:
1. Place the mounting bracket in the desired location.
2. Mark and drill the four mounting holes for the fastener you are using.
3. Fasten the bracket to the surface using the appropriate fastener.
4. Insert the GPSMAP 135 Sounder into the mounting bracket. The bracket is designed for a
tight fit to provide additional support when swiveling the unit.
5. Screw the two mounting knobs through the bracket and into the display case.
6. Connect the power/data and antenna cables to the back of the unit, making sure the
locking rings are fully tightened on both connectors.
