Safe use

• Keep the device dry.
• Do not expose the device or its battery to high temperature areas or place near
heat-generating devices such as flames, direct sunlight, heaters, microwaves and
ovens.
• When charging the device, plug the charger into an outlet that is within easy reach
of the device.
• Do not dispose of this device or its accessories in household waste streams.
• Do not use non-officially certified chargers, mobile power banks or batteries.

Medical device safety
• Please comply with the rules and regulations of the facility when using this device
in a medical environment such as a hospital or rehabilitation facility.
• Keep the device at least 15cm away from implanted medical devices such as
pacemakers and cochlear implants during use.
• The radio waves generated by the device may interfere with the operation of
implanted medical devices or other medical equipment. If you use one of these
devices, contact your device manufacturer to inquire about restrictions on your
use of the device.
Cleaning the device
• Do not use the device for extended periods in dusty environments such as
workshops, factories and deserts to prevent minute particles entering the device
and causing a drop in performance or other faults.
• Do not allow liquid or powdered substances to stick to the surface of the device or
accessories. This prevents the laser lens from becoming rusty or getting
scratched. If there is liquid or powder on the laser lens, use a soft, dry cotton or
silk cloth to lightly wipe clean.
