2 ADJUSTMENTS AND CHECKS
2-1 Test Mode
In Standby mode, press and hold the STOP + PLAY + PAUSE keys
simultaneously for 5 seconds. The display will show the model
name and the system controller's version number, and the test
mode is initiated.
Press the STOP key to exit from the test mode and return to the
standby mode.
2-1-1 Front key check
1. Press the PLAY key to enter the front key check mode.
2. The display shows the name of each key to be checked; press
the corresponding key.
When the check result of the key is OK, the display shows
another key name. When the result is No Good, the display
continues to show the same key name. timer play
3. When all of the keys have been checked, the display shows
"timer play". Follow this instruction by checking the dial50
TIMER slide switch operation.
4. The display finally shows "dial50". Check the MULTI JOG
dial so that the displayed figure increases when the dial is
rotated clockwise and decreases when it is rotated
counterclockwise.
5. Press the PLAY key to exit from the front key check mode and
return to the Version number display mode.
2-1-2 Display check
1. Press the DISPLAY key to enter the display check mode.
2. Press DISPLAY key a few times and ensure that each press
lights the display blocks one after another.
3. When all the indicators are lit, press the DISPLAY key to exit
from the display check mode and return to the Version number
display mode.
2-1-3 EEPROM default setting
1. Press the ERASE key.
This writes the default values in the EEPROM and checks the
written data. When the default data is written correctly, the
display shows " EEPROM OK !! ". If not, it shows EEPROM OK !! EEPROM
"EEPROM NG !!". NG !!
2. Press the ERASE key again to return to the Version number
display mode.
2-1-4 Total recording time display
1. When the RECORD key is pressed, the display shows the time
in which the pickup outputs the recording power (in the unit of
hour).
2. Press the RECORD key again to return to the Version number
display mode.
