HEAD SWITCHING FUNCTION
This unit is equipped with 4 double azimuth heads.
Under normal conditions, recording and playback is done
using the main heads “A1” and “B1”.
If a problem occurs with the main heads, for example if
only one channel is being recorded and playback cannot
be done, you can temporarily switch to the secondary
heads so that the playback picture can be viewed.
(If a problem occurs with the main heads, it is
recommended that you have the unit repaired as soon
as possible.)
