INSULATED FROM THE SUPPLY CIRCUIT ) BEFORE
THE APPLIANCE RETURNED TO THE CUSTOMER.
NOTES
1. Resistor values are indicated in
ohms unless otherwise specified
[ k = 1.000 m = 1.000.000 ]
2. Capecitor values are indicated in
microfarades unless otherwise
specified.
[ p = micro-microfarades ]
3.
: These resistor are to be
segregated from printed wiring board
