How to Replace the Fuses

The fuse in the hull and transceiver units protect them from overvoltage, equipment
fault and reverse polarity of the ship's mains. If the power cannot be applied first check
that the power cable between the transceiver unit and the display unit is firmly con-
nected. If the power still cannot be applied, the fuse in the transceiver unit may have
blown.
Have a qualified technician check and change the fuse.
