The amount of'time which a VTR needs to achieve stable tape movement after
receiving a start command is called the start delay. For precise synchronization
between VTRs, you need to measure the start delay of each connected VTR.
However, you do not need measure the start delays if the unit is able to determine
the type of your VTRs, and if you have selected Auto under setup menus items 12,
13 and 14 (RECORDER START DELAY, PLAYER 1 START DELAY and
PLAYER 2 START DELAY).

To
rneasure ctart delayc -
Insert a tape containing recorded material into each VTR and press the LEARN
button.
The tapes begin to run, and the unit measures the s t z t delays. This information is
saved in the unit's interna1 memory. It remains available for at least 100 hours after
the unit's power is turned off (provided that the unit has heen powered on for at
least two hours).
m
When VTR connections are changed, or when the previously measured s t a t delay
data has been lost, measure the start delays again Note that s t a t delays cannot be
measured unless a tape is loaded in each powered-on VTR. To exclude a VTR
from the measurement, disconnect the VTR or turn it off During the measurement,
tapes are rewound for about 5 seconds and played for about 7 seconds, so delays
cannot be measured from the very beginning or the very end of a tape
