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

CAUTION:

KEEP

the transceiver and microphone at

least 1 meter away from your vessel’s magnetic navigation
compass.

q

Using the template on the last page, 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 2 supplied bolts (M5

×

8 mm) on either side of

the IC-M502A.

r

Attach the clamps on either side of the IC-M502A.

• Make sure that the clamps align parallel to the IC-M502A’s body.

t

Tighten the end bolts on the clamps (rotate clockwise) so
that the clamps press firmly against the inside of the in-
strument control panel.

y

Tighten the locking nuts (rotate counterclockwise) so that
the IC-M502A is securely mounted in position as below.
