SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on schemat-
ics or by special notes on the parts list. Use only replacement parts that have critical character-
istics recommended by the manufacturer.
2. Make leakage current or resistance measurements to determine that exposed parts are
acceptably insulated from the supply circuit before returning the unit to the customer. Use the
following checks to perform these measurements:
A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord
directly into a 1 0V AC outlet. (Do not use an isolation transformer during this test.) Use a
leakage current tester or a metering system that complies with American National Standards
Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL)
149 (71). With the unit AC switch first in the ON position and then in OFF position, measure
from a known earth ground (metal waterpipe, conduit, etc.) to all exposed metal parts of the
unit (antennas, handle bracket, metal cabinet, screwheads, metallic overlays, control shafts,
etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any
current measured must not exceed 0.5 milliamp. Reverse the unit power cord plug in the outlet
and repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN
INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RE-
TURNING THE UNIT TO THE CUSTOMER.
B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a
jumper wire between the two prongs of the plug. ( ) Turn on the power switch of the unit. (3)
Measure the resistance with an ohmmeter between the jumpered AC plug and each exposed
metallic cabinet part on the unit. When the exposed metallic part has a return path to the
chassis, the reading should be between 1 and 5. Megohms. When there is no return path to
the chassis, the reading must be "infinite". If it is not within the limits specified, there is the
possibility of a shock hazard, and the unit must be repaired and rechecked before it is returned
to the customer.
ELECTROSTATIC DISCHARGE SENSITIVE (ESDS)
DEVICE HANDLING
This unit contains ESDS devices. We recommend the following precautions when repairing,
replacing or transporting ESDS devices:
• Perform work at an electrically grounded work station.
• Wear wrist straps that connect to the station or heel straps that connect to conductive
floor mats.
• Avoid touching the leads or contacts of ESDS devices or PC boards even if properly
grounded. Handle boards by the edges only.
• Transport or store ESDS devices in ESD protective bags, bins, or totes. Do not insert
unprotected devices into materials such as plastic, polystyrene foam, clear plastic bags,
bubble wrap or plastic trays.
