CONNECTIONS AND MAINTENANCE

 

■

MB-132 installation

An optional MB-132 

flush

 

mount

 is available for mounting 

the transceiver to a flat surface, such as an instrument panel.

KEEP

 the transceiver and microphone at least 1 meter 

away from your vessel’s magnetic navigation compass.

 

q

 Using the template on page 95, carefully cut a hole into 
the instrument panel, or wherever you plan to mount the 
transceiver.

 

w

Slide the transceiver through the hole, as shown below.

 

e

 Attach the clamps on either side of the transceiver with two 
M5 × 8 mm supplied bolts.

  • Make sure that the clamps align parallel to the transceiver body.

 

r

 Tighten the end bolts on the clamps (clockwise) so that the 
clamps press firmly against the inside of the instrument 
control panel.

 

t

 

Tighten the locking nuts (counterclockwise) so that the 
transceiver is securely mounted in position, as shown below.

 

y

 Connect the antenna and power cable, then return the in-
strument control panel to its original place.
