Preface
Safety Precautions
z
High Voltage
High voltages are used in the transmitter section which could be life threatening. A
protection cover with the words
Danger High Voltage
is provided in this section but
wait 10 minutes before inspecting inside.
Even if the power switch is turned off, residual voltages may remain in the capacitors
inside the unit. Before inspection or replacement of parts, discharge this residual
voltage in a safe and correct manner.
z
Disconnect Main Power
It is still possible to receive an electric shock caused by unintentionally switching on
the power during repair work. To prevent this from happening, make sure to
completely disconnect the unit from the ship’s main supply before attempting any
inspection.
z
Dust
Dust can accumulate inside after long periods of use. Allergies can result from the
inhalation of this dust, therefore during inspection and cleaning it is advisable to use a
mask.
z
Static Electricity
Static sensitive semiconductor devices are used in this unit. Before changing the
printed boards be careful not to damage any of these devices due to electrostatic build
up from carpet, clothes, seats, etc.
