such as Simpson Model 229-2 or equivalent between the
earth ground and all exposed metal parts of the appliance
(input/output terminals. screwheads, metal overlays, control
shaft. etc). Plug the AC line cord of the appliance directly
into a 120V AC 60H: outlet and turn the AC power switch
on. Any current measured must not exceed 0.5mA.

not be above
0.5mA

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance
have special safety related characteristics. These are

afforded by them necessarily can be obtained by using
replacement components rated for voltage, wattage, etc.
Replacement parts which have these special safety
characteristics are identified in this Service Manual.

Electrical components having such features are identified
by marking with a A on the schematics and on the parts list
in this Service Manual.

The use of a substitute replacement component which does
not have the same safety characteristics as the ONKYO
recommended replacement one, shown in the parts list in
this Service Manual. may create shock, fire, or other hazards.

Product Safety is continuously under review and new
instructions are issued from time to time. For the latest
information. always consult the current ONKYO Service
Manual. A subscription to, or additional copies of. ONKYO
