electrical ground. This will minimise electric shock and

mutual interference. In short, the UE must be grounded

to the vessel.

Service

Do not attempt to access to the interior of the UE. Only

qualified personnel authorized by its manufacturer may

perform service. Failure to comply with this rule will result

Under certain conditions, dangerous voltages may exist

even with the power cable removed. To avoid injuries,

always disconnect power before accessing the UE.

maintained around all sides of the unit except the bottom side. The ambient temperature range

Fire Precautions

The equipment shall not be operated in the presence of flammable gases or fumes as well as

any explosive atmosphere. Operation of any electrical equipment in such an environment

constitutes a definite safety hazard.
