2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance
have special safety related characteristics. These are often
not evident from visual inspection nor the protection
afforded by them necessarily can be obtained by using
replacement components rated for voltage, wattage, etc.
Replacement parts which have these special safety charac-
teristics 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
dose not have the same safety characteristics as the
PIONEER 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 PIONEER Service
Manual. A subscription to, or additional copies of, PIONEER
Service Manual may be obtained at a nominal charge from
PIONEER.

WARNING!

Lithium batteries. Danger of explosion.

Replacement must be done by qualified
personnel and only by following the
instructions given in the service manual.

This warning is stated on the product or in the
operating instructions. When replacing the
lithium batteries, follow the note below.

The batteries must be replaced only by batter-
ies of the same type and manufacture.
