sub 15-pin connector and confirm that the transmitted
data is received.
n
Do not connect to the D-sub 9-pin connector.
The transmitted data's times are indicated the "AU-
DIO LEVEL METER L" LEDs and the received
data's times are indicated the "AUDIO LEVEL
METER R" LEDs.
Confirm that the ten LEDs from the bottom of the
"AUDIO LEVEL METERs L and R" light.
After the test, disconnect the connector tool for loop
back test from the D-sub 15-pin connector, re-connect
it to the D-sub 9-pin connector and put the [SHIFT]
key to go to "(2) Confirmation of D-sub 9-pin Connec-
tor (RS-232C)".
(2) Confirmation of D-sub 9-pin Connector (RS-232C)
