Safety Summary

The following general safety precautions must be observed during all phases of operation, service, and repair of

this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual

could result in personal injury or damage to the equipment.

The safety precautions listed below represent warnings of certain dangers of which Motorola is aware. You, as

the user of the 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 plugged into an approved

three-contact electrical outlet, with the grounding wire (green/yellow) reliably connected to an electrical ground

(safety ground) at the power outlet. The power jack and mating plug of the power cable meet International

Electrotechnical Commission (IEC) safety standards and local electrical regulatory codes.

Do Not Operate in an Explosive Atmosphere.

Do not operate the equipment in any explosive atmosphere such as in the presence of flammable gases or fumes.

Operation of any electrical equipment in such an environment could result in an explosion and cause injury or

damage.

Keep Away From Live Circuits Inside the Equipment.

Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other

qualified service personnel may remove equipment covers for internal subassembly or component replacement

or any internal adjustment. Service personnel should not replace components with power cable connected. Under

certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, such

personnel should always disconnect power and discharge circuits before touching components.

Use Caution When Exposing or Handling a CRT.

Breakage of a Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To

prevent CRT implosion, do not handle the CRT and avoid rough handling or jarring of the equipment. Handling

of a CRT should be done only by qualified service personnel using approved safety mask and gloves.

Do Not Substitute Parts or Modify Equipment.

Do not install substitute parts or perform any unauthorized modification of the equipment. Contact your local

Motorola representative for service and repair to ensure that all safety features are maintained.

Observe Warnings in Manual.

Warnings, such as the example below, precede potentially dangerous procedures throughout this manual.

Instructions contained in the warnings must be followed. You should also employ all other safety precautions

which you deem necessary for the operation of the equipment in your operating environment.

Warning

War ni ng

To prevent serious injury or death from dangerous voltages, use extreme

caution when handling, testing, and adjusting this equipment and its

components.

Flammability

All Motorola PWBs (printed wiring boards) are manufactured with a flammability rating

of 94V-0 by UL-recognized manufacturers.

EMI Caution

!

Caution

This equipment generates, uses and can radiate electromagnetic energy. It

may cause or be susceptible to electromagnetic interference (EMI) if not

installed and used with adequate EMI protection.

Lithium Battery Caution

This product contains a lithium battery to power the clock and calendar circuitry.

!

Caution

Danger of explosion if battery is replaced incorrectly. Replace battery only

with the same or equivalent type recommended by the equipment

manufacturer. Dispose of used batteries according to the manufacturer’s

instructions.

Attention

!

Caution

Il y a danger d’explosion s’il y a remplacement incorrect de la batterie.

Remplacer uniquement avec une batterie du même type ou d’un type

équivalent recommandé par le constructeur. Mettre au rebut les batteries

usagées conformément aux instructions du fabricant.

Vorsicht

!

Caution

Explosionsgefahr bei unsachgemäßem Austausch der Batterie. Ersatz nur

durch denselben oder einen vom Hersteller empfohlenen Typ. Entsorgung

gebrauchter Batterien nach Angaben des Herstellers.

CE Notice (European Community)
