5-7-2. FWD Search and REV Search
Check
1. Set the REV seach mode.
Check that the pitches of the peaks of the RF
waveform are equal.
If not equal, perform 5-4. Tracking Adjustment
and 5-6. TG-7 and TG-8 Guides Adjustment.
2. Set the FWD search mode.
Check that the pitches of the peaks of the RF
waveform are equal.
If not equal, perform 5-4. Tracking Adjustment.
5-7-3. Rising Check
1. Open the PLAY mode, and check that the RF
waveform rises horizontally within one second
(from when the RF waveform appears on the
oscilloscope). Check that the tape does not slack
near the capstan at this time.
2. When the PLAY mode is set after the FWD
search/REV search mode, and FF/REW mode,
check that the RF waveform rises horizontally
within one second. Check that the tape does not
slack near the capstan at this time.
