♦ Continuous IRM rotation
Press the [IRM STOP] key to change the display into [IRM ROT], and the IR
motor will rotate continuously. Press the [IRM ROT] key again to change the
display into [IRM STOP], and the IR motor will stop.
* * * When a motor have been stopped and noised because of the depth of
gearing, set the power to OFF once and start to rotate again.
* * * After turning on the M. LED and rotating the IR motor, make optical
adjustments on the IR (image rotator), and check the accuracy of the
rotation and the position of the photo detector unit.
Connect the oscilloscpe to TP18 (XAL) and TP17 (YAL).

• Adjusting the model eye position
Adjust the position of the model eye tool installed on the centering tool so that the
following readings are obtained:
XAL = +000 YAL = +000
TOT = 093 approx. (OK if read-out is between 60 and 105)
Adjust the center position roughly while referring to the position of the asterisk “ * ”
mark in the alignment position display located at the upper left corner.
(Set the focus point to the fifth graduation of the scale in the model eye attaching
tool.)
Finally, install the dust - proof glass and adjust VR3 GAIN until TOT=080 ~085
reading is obtained.
• Adjusting the alignment mark position
After adjusting the model eye position, do the following if the blinking dot of the
M.LED is misaligned slightly from the alignment mark:
Move the alignment mark vertically with the [U] and [D] keys and horizontally
with the [L] and [R] keys until the blinking dot of the M. LED falls at the center of
the alignment mark.
After the adjustment is complete, turn DIP switch No. 5 located on the right side of
the Main body to the ON position and press the [SET] key.
The alignment mark position is then stored in the EEPROM and the message “SET
DIP SW5 TO OFF” is displayed. Return DIP switch No. 5 to the OFF position.
