Power On/Off - LUNA OPTICS QUANTUM DIGITAL 2K Instruction Manual

1, To install the batteries, see the above vertical picture of the bottom of the binocular. Slightly press
the thumb icon on the battery cover (16) with thumb, and at the same time, slide the battery cover
according to the red arrow direction. Now the battery compartment is open. Then place the woven
tape at the bottom of the battery container and install four CR123A or CR123R batteries. Pay
attention to the icons of the battery positive pole and negative pole positions on the battery container.
Finally, adjust the woven tape position and replace the battery cover by gently sliding it in until it
firmly clicks in place. If installed correctly, when it's time to remove the batteries, you should be able
to do it by gently pulling out the woven tape.
2, Please be aware that rechargeable CR123R batteries usually have much lower capacity than
non-rechargeable CR123A batteries, therefore working time will be greatly reduced if using
rechargeable batteries, especially if features like IR illuminator and/or videorecording and Wi-Fi are
activated.
3, Best option of powering the binocular is via external battery pack or 5V/2A power bank. This
method will provide the longest possible working time. External power sources can be connected
via the USB-C port (13).
Attention:
1, When installing batteries, the direction of battery positive pole and negative pole must be correct.
If the battery direction is wrong, the device will not operate.
2, The voltage of the external power bank cannot exceed 5V. Otherwise, it will burn out the
device circuit system and void any warranty claims.
3, To ensure a longer lifespan of the device, the internal USB-C port cannot charge the batteries
inside the device. The CR123R batteries need to be charged in an external charger.
Power On / Off
To start the device, press and hold the power button (7) for 3 seconds.
The power on indicator (9) will turn bright green.
On the screen, you can briefly see the word "Welcome" through the eyepieces (10).
To shut down the device, press and hold the power button (7) for 5 seconds.
On the screen, you can see a progress bar powering off. Do not let go of the power
button until the image completely disappears from the screen, indicating the device
is off.
Focusing the eyepieces and objective lens
Remove both protective lens covers (4). After turning on the device, users can see the image through
two eyepieces (10). Rotate the two eyepiece adjustment wheels (8) and (11) individually and focus
on the icons and words on the image displays. Next, adjust the distance between two eyepieces by
sliding the eyepieces either towards or away from each other. When icons and words are sharp
and clear on screen and image appears as one single display, you have completed focusing the
eyepieces well.
