CAUTION : For continued safety, replace safety
critical components only with manufacturer's rec-
ommended parts (refer to parts list).
Indicates safety critical components. To reduce
the risk of electric shock, leakage-current or resis-
tance measurements shall be carried out (ex-
posed parts are acceptably insulated from the
supply circuit) before the appliance is returned to
the customer.
• DC voltages are as measured with a high im-
pedance voltmeter. Values may vary slightly
due to variations between individual instruments
or/and units.
