1. ABOUTLEADFREE SOLDER(PbF)
Distinction of PbF PCB:
PCBs (manufactured) using leadfree solderwill have a PbF stamp on the PCB.
Caution :
-Pbfree solderhas ahighermelting pointthanstandard solder;
Typicallythemelting pointis50 -70°F(30 -40°C) higher. Please
use asoldering iron withtemperaturecontrol and adjust itto700 ±
20°F(370 ±10°C). Incase ofusing high temperaturesoldering
iron, please becareful nottoheat too long.
-Pbfree solderwill tend tosplashwhenheatedtoo high (about
1100°F/600°C)
-Thisleadfree solderwill beusedfor theproducts afterserial No.

-ACD-R and aCD-RWthat holdCD-DAdata canbereproduced.
-WithACC OFF, Eject Function.
-TheCD changercanbemountedat anyofthefollowing 5angles:

3. REPLACINGTHE FUSE
Use fuses of the same specifiedrating (3amps). Using different substitutes orfuses with higher
ratings, orconnecting the productdirectlywithout a fuse, couldcause fire ordamage to the
stereounit.
4. MAINTENANCE
Yourproductis designedand manufacturedto ensure a minimum of maintenance. Use a dry, a
soft cloth forroutine exteriorcleaning. Neveruse benzine, thinnerorothersolvents.
5. NOTES
[CD DECK BLOCK]
This model has no servoalignment points because microcomputercontrols the servocircuit.
