SAFETY
Important Note!!!
Do the following safety checks after servicing this unit.
1. Remove all the externally connected test equipment and wires before testing the unit.
2. Use the safety test circuit as shown below.
3. Plug the power cord or unit to be tested into the test receptacle.
4. Switch the unit being tested to ON or PLAY.
5. Connect external jack/terminal contact VTVM across a 1k resistor in the test circuit. Set the meter
to a
high (150V AC) scale to avoid meter damage and then touch the points with the test probe.
If the meter reading indicates less than 3 volts on all test points, set the meter to a low (3V AC) scale
and repeat the test.
6. Any reading greater than 0.2 volt indicates a potential shock hazard. If this occurs, determine
the
cause of the leakage, correct the problem, and repeat the safety test.
