SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on schematics
or by special notes on the parts list. Use only replacement parts that have critical characteristics
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 120V 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)
UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. 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 RETURNING 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. (2) 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 testing 3 wire products, the resistance measured to the
product enclosure should be between 2 and infinite MOhms. Also, the resistance measured to
exposed input/output connectors should be between 4 and infinite MOhms. When testing 2 wire
products, the resistance measured to exposed input/output connectors should be between 4
and infinite MOhms. 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.
