Depending on your activity, you can position the head
display so that the image takes up the whole field of
vision, or you can keep it in your peripheral vision to
keep both eyes on your work. Follow these tips to
ensure that you can see the whole image:
• To keep the image in your field of view
at all times, position the head display
right in front of your eye and make sure
that the lens is facing towards the eye.
• To keep the image in your peripheral
vision (so that it is only seen when you
move your eyes in that direction),
position the head display at the edge of
your field of view and make sure that
the lens is facing your eye. If the entire
image is not visible, change the angle
of the head display or switch to Reduce mode.
• If the ball joints become loose after adjusting
the position of the head display, turn the dials
on either end of the flexible arm clockwise to
fix the head display in place.
• If you cannot see the full image after adjusting
the flexible arm, you may have to adjust the

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.
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.

joints by rotating their respective dials
clockwise.
Run the head display cable through the cable channel on
the flexible 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.
Adjusting the Settings
25
Note When attaching the head display cable to the

27
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.
28
Power supply
Important • The AiRScouter can use the following power
supplies:
- The AC adapter supplied in the box
- The internal battery supplied for use
inside the control box
- An external battery (for example a thirdparty USB battery) that supplies a voltage
of DC 5 V and a current of at least 1 A
• If multiple power supplies are connected to
the AiRScouter at the same time, they will be
prioritised in this order:
1 AC adapter
2 External battery
3 Internal battery
Example:
- If an external battery is disconnected
while the AiRScouter is in use, the
system will switch to using the internal
battery.
- If an external battery is connected while
the AiRScouter is using the internal
battery, the system will switch to using
the external battery.
Adjusting the Settings
• The internal battery will not charge while the
AiRScouter is turned on. To charge the
internal battery, you must power off the
AiRScouter and connect the AC adapter.
• The external battery cannot be used to
charge the internal battery. The internal
battery can only be charged by the AC
adapter.
29
Important • You cannot charge the AiRScouter by
connecting it to a computer with a USB cable.
• If a USB-AC conversion adapter is used as
the external power supply for the AiRScouter,
ensure that the adapter supplies a voltage of
DC 5 V and a current of at least 1 A.
• If the AiRScouter becomes hot to the touch
due to continuous use, or if the environmental
conditions are outside of the recommended
range, the external power LED will begin to
flash quickly. While the AiRScouter is in this
state, the internal battery cannot be charged.
Using an External Battery
You can use a third-party USB battery as an external power
source to extend the operating time of the AiRScouter
beyond that supported by the internal battery.
Important • Only use a third-party external battery that
can supply a voltage of DC 5 V and a current
of at least 1 A.
• The external battery cannot be used to
charge the internal battery. The internal
battery can only be charged by the AC
adapter while the AiRScouter is powered off.
30
Before connecting an external battery to the control box,
1
2
3
ensure that the external battery has been fully charged.
(For more information on charging a third-party USB
battery, see the battery’s manual.)
Connect the Micro-USB B plug of a USB Type-A to MicroUSB B cable to the Micro-USB B port of the control box.
Adjusting the Settings
Connect the USB Type-A plug to the USB Type-A port of
the external battery.
31
The external power LED on the control panel will turn
4
orange when an external battery is connected and
supplying power to the AiRScouter.
• The external power LED will turn off when the external
battery is discharged.
• If the internal battery is charged, the system will
automatically switch to use the internal battery.
32
5. Maintenance
Clean the Lens
If the lens becomes smudged or dirty, you may not be able
to clearly see the image on the head display. If this occurs,
clean the lens as described below.
Important Use a soft cloth for cleaning the lens. Never
use ethanol, organic solvents, or organic
chemicals. Such substances could cause the
lens coating to peel off the anti-reflection film,
so that the image will not be seen correctly.
Use a soft cloth to wipe away dirt and dust from the lens.
Maintenance
33
Clean the Head Band
If the head band pads become dirty, they can be wiped
clean with a dry cloth. If this is insufficient to clean the
pads, they may be cleaned with ethanol, but take care to
prevent any splashing onto the lens.
Clean the Control Box
Dirt and dust can be removed from the control box by
wiping it clean with a dry cloth. If this is insufficient, you
can use a moistened cloth, but make sure that it is well
wrung to minimise the risk of getting water into the control
box.

• Using or storing the Li-ion rechargeable battery in
places that are too hot or cold may cause them to
deteriorate more quickly. In particular, usage at a high
charge rate (90% or more) in a hot place greatly
accelerates the deterioration of the Li-ion rechargeable
battery.
• If this product will not be used for a month or more, take
the Li-ion rechargeable battery out of the control box,
and store it in a cool place out of direct sunlight.
• Charge the Li-ion rechargeable battery every six months
if it is left unused for a long period.
• The device may feel warmer if it is touched while the
Li-ion battery is charging. This is normal, and the device
can be used safely. Stop using the device if the control
box gets extremely hot.
