Switch the head display to be viewed with
the right eye
While the AiRScouter is supplied with the head display screen on the
left side of the head band, the flexible arm may be switched to allow
the head display to be positioned over the right eye instead.
1. Ensure that the AiRScouter is powered off.
2. Remove the head display cable from the cable channel on the head
band, and from the cable channel on the flexible arm.
3. Rotate the dial on the ball joint between the flexible arm and the head
band clockwise, until the flexible arm is separated from the head band.
4. Rotate the dial on the ball joint between the flexible arm and the head
display clockwise, until the flexible arm is separated from the head
display.
5. Turn the head band over so that the threads of the ball joint face the
other way, and the AiRScouter logos on the head band covers are
upside-down.
6. Remove the two head band covers as shown, by pressing the area
highlighted in the image below and sliding the cover to the end of the
head band. Swap the two covers and replace them as shown, so that
the AiRScouter logos are now facing the correct direction.
7. Attach the flexible arm for right-eyed viewing (the other arm that is
included in the box) to the head display by lining up the narrow end of
the flexible arm with the threads on the head display, and rotating the
dial on the ball joint clockwise to tighten.
8. Attach the flexible arm to the head band by lining up the wide end of the
flexible arm with the threads on the head band, and rotating the dial on
the ball joint clockwise to tighten.

arm, and then through the cable channel on the top of the head band.
Secure the head display cable into the clip on the end of the head band,
to prevent it from coming loose during operation.
10. Press the power button to turn the AiRScouter on.
Note
The flexible arm for left eye and the flexible arm for right eye are two
separate parts that are included in the AiRScouter box. Because of its
design, the flexible arm for right eye cannot be used for left-eyed
viewing, and vice versa.
Note
To prevent movement of the arm during operation, you can tighten one
or both ball joints by rotating their respective dials clockwise.
Note
When attaching the head display cable to the flexible arm and head
band, ensure that you leave enough slack so that you do not pull the
head display cable during adjustment and operation.
Note
To return the AiRScouter to left-eyed viewing, follow the same
instructions, using the flexible arm for left eye instead of the flexible arm
for right eye.

Replace the Eyecup
Depending on your task or environment, you may want to replace the
small eyecup attached to the head display with the large eyecup that is
included in the box. The large eyecup will isolate your eye and the
screen from your working environment.
1. Carefully remove the small eyecup from the head display as shown.
2. Correctly align the large eyecup, and then gently press the eyecup to
attach it to the head display.
Important
 Be careful to avoid touching the lens while changing the eyecup. You may
dirty or damage the lens if you touch it.
 Be careful to align and attach the eyecup correctly. The eyecup or head
display may be damaged if it is incorrectly aligned or forced into place.
