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 bazard to the
service technician.
3. Even units with polarized power plugs are often "hot
chassis" type. Treat my piece of equipment with a
two-wire power plug as "hot chassis” type and use the
isolation transformer for safety. There is no disad-
vantage 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 1604 Isolation Transformer
provides the necessary safety factor mentioned above. The
rugged, compact portable mit with its sturdy carrying
handle is ideal for home service calls as well as in the ser-
vice shop. 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 occassional defective or "power hungry" unit
when cycled 5 minutes on and 5 minutes off. Overload pro-

former to 120 volt, 60 Hz ac wall outlet.
Connect power plug of equipment under test to outlet

If OVERLOAD circuit breaker on front panel of unit
trips after a few minutes operation, allow 5 minutes
for cooling, then PUSH TO RESET.
If OVERLOAD circuit breaker trips immediately or
after only à few seconds operation, the unit is severely
overloaded. The equipment under test may be shorted.
Do not PUSH TO RESET until the overload is removed.
