and date data) is input from an external source, time and date are displayed according
to the received data.

How to Replace Fuses
The processor unit, transceiver unit and hull unit carry fuses that protect the system
from overvoltage and equipment fault. If the power cannot be applied, check the fol-
lowing.
• Check the fuse in the processor unit.
• Check the circuit breaker in the transceiver unit. (The breaker is behind the lid at the
front-right bottom corner of the unit.)
Find the cause before replacing a fuse. If the fuse blows again after replacement, con-
tact your dealer for advice.
