SAFETY CHECK-OUT (US Model) MODEL IDENTIFICATION
— Specification Label —
After correcting the original service problem, CDP-C701ES
perform the following safety check before releasing CDP-C801ES
the set to the customer:
Check the antenna terminals, metal trim, ‘“‘metallized”’
knobs, screws, and all other exposed metal parts for SON Ye move. no. ZZ

LEAKAGE TEST
The AC leakage from any exposed metal part to
earth ground and from all exposed metal parts to any
exposed metal part having a return to chassis, must
not exceed 0.5mA (500 microampers). Leakage
current can be measured by any one of three
