BEFORE RETURNING THE RECEIVER
Before returning the receiver to the user, perform the following safety Checks.
1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not
lodged between the chassis and other metal parts in the receiver.
2. Inspect all protective devices such as non-metallic control knobs, insulating fishpapers,
cabinet backs, adjustment and compartment covers or shields, isolation resistor- ca-
pacity networks, mechanical insulators etc.
