CAUTION : For continued safety, replace safety
critical components only with manufacturer's rec-
ommended parts (refer to parts list).
Indicates safety critical components. To re-
duce 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 voltmeter. Values may vary slightly
due to variations between individual instru-
ments or/and units.
