CAUTION :

 For continued safety, replace safety critical com-

ponents only with manufacturer's recommended parts (refer to
parts list).

 Indicates safety critical components. To reduce the risk of

electric shock, leakage-current or resistance measurements
shall be carried out (exposed parts are acceptably insulated
from the supply circuit) before the appliance is returned to the
customer.

• DC voltages are as measured with a high impedance volt-

meter. Values may vary slightly due to variations between
individual instruments or/and units.
