SAFETY CHECK-OUT
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
This appliance is classified as Check the antenna terminals, metal trim, "metallized" knobs, screws,
a CLASS 1 LASER product. and all other exposed metal parts for AC leakage. Check leakage as

located on the rear exterior. LEAKAGE
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 0.5 mA (500 microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers' instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245

is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples of
a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2V AC range are suitable. (See

Some of the signal of remote commander vary between generation
of player.
Between DAV-S400/S500/S800/C450/C700/C900 and DAV-S550/

"FUNCTION", "BAND", "ST/MONO" and "MEMORY" are
different.
Take notice of the above when you check the operation with remote
