1—4 Notes
1. Use a 10:1 probe for the oscilloscope.
2. All the knob positions (settings) for the oscilloscope in the adjustment procedures are for when a 10:1 probe is
used.
1-5 Test mode
These models have a test mode so that the adjustments and checks required for service can be carried out easily. When
these models are in test mode, the keys on the front panel work differently from normal. Adjustments and checks can be
carried out by operating these keys with the correct procedure. For these models, all adjustments are carried out in test
mode.
(Setting these models to test mode]
How to set this model into test mode.
1, Turn off the power switch. For Multi-play CD type, unplug the power cord from the AC socket.
2. Short the test mode jumper wires. (See Figure 1.)
3. Turn on the power switch. For Multi-play CD type, plug the power cord back into the AC socket.
When the test mode is set correctly, the display is different from what it usually is when the power is turned on. If the
display is still the same as usual, test mode has not been set correctly, so repeat Steps 1-3.
