ïUsing the optional mounting bracket

An optional MB-75 FLUSH MOUNT is available for mounting the transceiver to a ﬂat surface such as an instrument panel.

CAUTION: KEEP the transceiver and microphone at

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

qUsing the template on the last page, carefully cut a hole into the instrument panel (or wherever you plan to mount

the controller).

wSlide the transceiver through the hole as shown below.

eAttach the 2 bolts supplied (M5 ⋅ 8 mm) on either side of the IC-M503.

rAttach the clamps on either side of the transceiver.

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

tTighten the end bolts on the clamps (rotate clockwise) so that the clamps press firmly against the inside of the in-

strument control panel.

yTighten the locking nuts (rotate counterclockwise) so that

the transceiver is securely mounted in position as below.

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