SAFETY INFORMATION
This product has been designed and manufactured according to FDA regulations "title 21, 1 For U.S.A.
CFR, chapter 1, subchapter J, based on the Radiation Control for Health and Safety Act of
1968", and is classified as a class 1 laser product. There is no hazardous invisible laser
radiation during operation because invisible laser radiation emitted inside of this product
is completely confined in the protective housings.
The label required in this regulation is shown 1.
OCAUTION
USE OF CONTROLS OR ADJUSTMENT OR PERFORMANCE OF PROCEDURES OTHER
THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

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. dial50
3. When all of the keys have been checked, the display shows
" dial50 ". Check the multi jog dial to confirm that the
displayed figure increases when the dial is rotated clockwise
and decreases when it is rotated counterclockwise.
4. 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.
