FAN is switched ON/OFF alternatively
whenever it selected.
The display shows FAN condition.
[16:DSP GA check]
( FACTORY ONLY TEST.NOT USE SERVICE. )

peak point.
[F6:Memory Check] Test the memory of the high speed S-
RAM which used in DSP GA.
[17:VS8F-2 check]
This is a test for the option board (VS8F-2), ESP and DSP in
order to find any wrong connection, chip defect or other
problems.
[F3:VS8F-2] Test the connection between VS-1680
and VS8F-2 and also test the VS8F-2
internal functions.
To start the test install VS8F-2 to the
option connector A and B on VS-1680
then select the test menu.
The display will show "OK!" messages
from both of connector A and B when
the test is successful, if not "Err"
message will be appeared on the
display.
