Maintenance & Care
1. Cleaning and Maintenance
1) This device is a precision instrument that deserves reasonably cautious care. The following tips are provided to
ensure a long product life. The optical lenses are multicoated optical glass. When cleaning the lenses, blow away
dust on the surface, wet the lens with lens cleaner or clean water, then wipe away smudges with lens tissue, soft
cotton, or a microfiber cloth. Avoid touching the glass surface with dry cloth or tissue paper. Do not use organic
solvents such as alcohol or acetone. No special maintenance is needed for the housing surface. Do not try to
dismantle the device as the internal parts are specially cleaned and sealed and with an anti-fog treatment. Any
such attempt will void the warranty.
2) If there is a shutdown phenomenon during use, please check whether the surface of the gold-plated parts in
the battery compartment is contaminated.
3) If the screen flickers during use, please clean the connector contacts according to the instruction from the
section "Removing or Replacing the Camera".
2. Software Upgrade
Download the upgrade file package to your computer and connect the device to your computer using the included
magnetic USB cable. After the device is turned on, copy the upgrade file to the storage root directory of the device
(the upgrade file name must be artosyn-upgrade-ars31.img) and then shut down the device. Hold the top right
button without releasing it, and then press the power button to perform a software upgrade. The blue indicator
light flashes during the software upgrade. After the flashing ends, the upgrade is complete.
