Replace the fourteen (14) fixing screws marked [850].
The top cover can then be Replaced. (Fig. 1)
7. Checking that the DB-SREV1 (CNV) Circuit
Board is Working Correctly
If the DB-SREV1 (CNV) circuit board is working correctly,
when the SREV1 is turned on the two rows of INPUT and
OUTPUT front panel indicators light up alternately in a
streaming pattern from left to right. If the indicators do not
light up like this, the DB-SREV1 (CNV) circuit board is not
working correctly, in which case you should check that it's
installed in accordance with these instructions.
8. Execute Test Program
Execute test program No. 5 in Section 5-2 and check if
operation is normal. (Refer to page 42.)
