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 precaution s listed below represe nt warning s of certa in danger s of which M otorol a is aware. You, as the user of the produc t, should follow these warnings and all other safety precau tions necessary for the sa fe operation of the equipment in your operating environment.

Ground the Instrument.

T o minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground. If the equipment i s suppl ied with a thre e-conduc tor A C po wer cable, t he po wer ca ble must be plug ged int o an ap prov ed three-contact electrical outlet, wit h the groun ding wire (g reen/y ello w) r eliab ly connecte d to an elec trica l ground (safety ground) at the power outlet. The power jack and mating plug of the p ower cable meet Internation al Electrotechnical C om mission (IEC) safety standards and local electric al regul at ory 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 el ectri cal equ ipmen t in such an environme nt co uld re sult in a n explosi on and c ause injury or damage.

Keep Away From Live Circuits Inside the Equipment.

Operating person nel must not rem ove equipment covers. On ly Factory Author ized Service Pe rsonnel or oth er qualified service pe rs onne l ma y rem ove eq uipm ent covers fo r int e rnal suba ss emb ly or co mpo ne nt re plac eme nt 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 shou ld always disconnect power an d di scharge circuits befo r e to uching component s.

Use Caution When Exposing or Handling a CRT.

Breakage of a Catho de-Ray Tube (CRT) causes a high -velocity scatte ring of glass fragm ents (implo sion). To prevent CRT impl osion, do not handle the CRT and avoid rough ha ndling or jarring of the equipment. Han dling 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 s ubstitute parts or perform any unau thorized m odification o f the eq uipment. Contact your loc al 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 co ntained in the warnings must be followed. You should also employ all other safety precaut ions which you deem necessary for the operation of the equ ipment in your operating environment.
