85 SQPB (H)
I
The distinction results whether S-VHS or VHS of the playback tape is input in VV
mode.
*"Low" is input: VHS tape playback.
*"High" is input: S-VHS tape playback.
NOTE: When the MESECAM (H) terminal receives "High", above result is invalidated
and the tape is judged to VHS tape playback.
*In case of model having SQPB function, ON/OFF setting of SQPB is performed with
above result, Envelope voltage and result wheather the CTL pulse exists not.
*In case of model not having SQPB function, above result is disregarded, and the
VCR is always set to SQPB = off.
