WARNING

1. Touching a “hot chassis” is hazardous and can cause fatal electrical shock. Most

television receivers and other equipment with a two-wire ac power plug are the “hot

chassis” type. To service such equipment, always connect an isolation transformer
between the wall outlet and “hot chassis” equipment.

2. Most “hot chassis” products have a plastic or wooden cabinet that insulates the

chassis and prevents the user from touching it. However, when the cabinet or back
is removed for servicing the product, the chassis is exposed and becomes an
electrical shock hazard to the service technician.

3. Even units with polarized power plugs are often “hot chassis” type. Treat any piece

of equipment with a two-wire power plug as “hot chassis” type and use the
isolation transformer for safety. There is no disadvantage to using the isolation
transformer, even in cases where it is not needed.

4. In addition to the electrical shock hazard, there is also a high probability of damage

to any ac powered test equipment used to service such equipment.

5. The isolation transformer may become very warm when operating at high output

current. Touch with care.

The B & K Precision Model 1604A Isolation Transformer provides the necessary safety
factor mentioned above. The 1.25 amp continuous output current rating is adequate for
almost any solid state television receiver. The 2 amp intermittent output current rating

offers enough reserve for the occas ional defective or “power hungry” unit when cycled 5

minutes on and 5 minutes off. Overload protection is provided by convenient front panel
OVERLOAD circuit breakers; simply PUSH TO RESET.
