5.2.1.1 Ship power

In some installations ship power might occasionally disappear for a short time, e.g. if

switching between land power or generator power. Your equipment will shut down immedi-

ately when power is failing. If the power does not arrive within 10 minutes the radio cannot be

expected to start up automatically.

5.2.1.2 Fuses

If a press on the ON/OFF button does not turn on the radio, and ship power is present, a fuse

might need replacement. The main fuse is located on the rear side of the radio. The shield is

removed and the fuse is simply replaced with a new one.

cally for a short time to check that they are functional. Pressing twice will exit the

test.

previous state.
