General Safety

Remember!. . . safety depends on you!

The following general safety precautions must be observed during all phases of operation,
service, and repair of the equipment described in this manual. Failure to comply with these
precautions or with specific warnings elsewhere in this manual violates safety standards of
design, manufacture, and intended use of the equipment. Motorola, Inc. assumes no liability for
the customer’s failure to comply with these requirements. The safety precautions listed below
represent warnings of certain dangers of which we are aware. You, as the user of this product,
should follow these warnings and all other safety precautions necessary for the safe operation of
the equipment in your operating environment.

Ground the instrument

To minimize shock hazard, the equipment chassis and enclosure must be connected to an
electrical ground. If the equipment is supplied with a three-conductor AC power cable, the power
cable must be either plugged into an approved three-contact electrical outlet or used with a three-
contact to two-contact adapter. The three-contact to two-contact adapter must have the grounding
wire (green) firmly connected to an electrical ground (safety ground) at the power outlet. The
power jack and mating plug of the power cable must meet International Electrotechnical
Commission (IEC) safety standards.
Note: Refer to “Grounding Guideline for Cellular Radio Installations”–Motorola part no.

Do not operate in an explosive atmosphere

Do not operate the equipment in the presence of flammable gases or fumes. Operation of any
electrical equipment in such an environment constitutes a definite safety hazard.

Do not service or adjust alone

Do not attempt internal service or adjustment unless another person, capable of rendering first aid
is present.
