CAUTION : For continued safety, re-
place safety critical components 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 mea-
surements shall be carried out (ex-
posed parts are acceptably insulated
from the supply circuit) before the ap-
pliance is returned to the customer.
• DC voltages are as measured with
a high impedance voltmeter. Val-
ues may vary slightly due to varia-
tions between individual instruments
or/and units.
