2. Precautions for Repair Work
Short Circuits:
Care must be taken to avoid short circuits. Soldering, solder dust, screws, metal clippings, metal wrist
watches etc. can cause short circuits on PCBs which may result in component damage.
Test Equipment Calibration:
Your test equipment should be calibrated before use. Frequent calibration is essential to ensure high
quality and reliable repairs.
Cleaning:
Before cleaning ensure that the telephone is switched off and disconnected from the power source.
Cleaning should be done using a soft dry cloth. If the equipment is heavily soiled a soft cloth soaked in
a mild synthetic detergent diluted in water may be used.
Never use benzene or any other chemicals to clean the equipment.
RF Shielding:
It is advisable to carry out detailed measurements and repair (in particular RX) in a shielded area to
minimise RF interference.
AC Adapter and Battery Charger:
The AC adapter and battery chargers are for indoor use only. Ensure that the devices are not exposed
to rain or moisture.
Electrical Safety:
Electrical equipment is hazardous if misused. Any repairs must be carried out with care and only by
authorised personnel.
Ensure all power sources are switched off and power cords removed before undertaking any repairs.
Hazardous Waste:
The battery pack, if incorrectly disposed of, is an environmental hazard. It must be disposed of in
accordance with the regulations of the country concerned. Never dispose of the battery pack in fire or
water.
Confidentiality:
The circuitry within this equipment contains several components that are regarded as company
confidential. Only use NEC specified parts as replacements.
RF Injury:
To avoid RF injury, direct exposure to radio frequency energy should be avoided. In particular,
exposed parts of your body (especially the eyes and face) should not come into contact with the
antenna while the equipment is transmitting.
