This mode consists of "player operation mode" and "test operation mode."
<Player operation mode>
Basic operation of Servo, such as setup, play, pause, and track search, is carried out.
Moreover, measurement of an error rate can also be performed.
<Test operation mode>
Servo operation is finely controllable gradually.
* It becomes player operation mode and shifts to test operation mode by the key input in the beginning.
B
* The command treated here is for mainly testing a mechanism and a servo system, and is not for DJ functions, such as scan
and tempo.

Play(Trace) / Pause
If it is in a stop state, it will set up and play. Moreover, if it is in a play state, whenever it will push a button, a pause and
a play are carried out by turns.
Display a playing address in FL at present.
Note: In this mode, even if it inserts a disc, an automatic setup is not carried out.
Moreover, a play is not carrying out audio reproduction, but is tracing the signal side of a disc.
Trace a disc by a turn of four times speed in the play. The sound is not output.
Track Search F/R
Search a track displayed by a FWD / REV direction and do pause.
Error Rate Count
E
I measure an error rate from a present position doing a play/pause for about 10 seconds and display a measurement result
in FL. Usually, a track to measure is made to search and this button is inputted from a pause state.
For example, it is displayed as "3.56E-4 O.K." etc.
If an error rate is less than 3.00E-3, it will be displayed as OK. If an error rate is larger than 3.00E-3, it will be displayed as
NG.
Measurement with the managed disc at the time of factory shipments is a premise.
The product does not judge whether they are inferior goods at the time of service.
Eject
A disc is ejected.
F Mode Change
If the MASTER TEMPO button is pushed into player operation mode, MASTER TEMPO LED will light up, and it will shift to
the below-mentioned "test operation mode."
