S-MD Test Mode
This mode is used by service personnel to solve problems when the mechanism is malfunctioned. Normally users do
not enter S-MD Test mode.
(1) Test mode input
1) How to input
Input in the same manner as with inputting in Test mode of CDS, CDM, etc.
To enter Test mode, reset the system and set ACC to ON or connect the detach grill, then press xx and xx keys (see
CD) simultaneously. Then, use the SOURCE key (or TAPE or SOURCE key on the remote control unit) to activate
MDS source, and input in MDS Test mode.
Normally, the system does not change to MDS source when no disc is loaded. In Test mode, the system changes to
MDS source without a disc loaded, and enters Test mode.
2) Beep sound
• With ’97 autumn or later models, the system beeps to confirm that the system has entered Test mode.
(2) Canceling Test mode
1) Internal MDS (P-BUS)
• With ’97 autumn or later models, reset the system, set ACC to OFF, BACKUP to OFF, or disconnect the detach grill
to cancel Test mode. (Set ctestf to 0 if Clear RAM is called as preprocessing of standby.)
2) Slave MDS (IP-BUS)
In addition to the method mentioned in 1), Slave MDS must be reset, too.
(3) Effective keys in Test mode
In Test mode, some keys require special key decoding.
