Maintenance
Regular maintenance can ensure that the device runs continuously and safely.
Meanwhile with improved maintenance, damage (such as device downtime and repair)
is reduced, and safety performance (personal injury) is improved.
8.1 General Maintenance
The power must be switched off before starting maintenance. When the entire system is
in working condition, do not try to clean any part of it.
For frequent cleaning, use a slightly damp cloth or cotton to wipe the device case and
surface.
DO NOT use any abrasive cleaner or organic solvent (such material is not allowed) or
cleanser with solvent (gasoline, alcohol or detergent is prohibited)!
DO NOT spray at the device! Never drip any cleanser into the machine!
8.2 Maintenance in System Running
a) Before turning on the device, make sure the supply voltage is in the allowable
range of the device (by observing the battery level indicator).
b) Turn on/off the device and perform daily operation as described in the operation
manual. Do not attempt any operation in device power-up/power-down process.
Shutting off the power supply directly may cause damage to device hardware
and software.
8.3 Regular Maintenance
a) If the device is not operated for a long time, charging once every two months,
and keep the power about 60% for storage. For low battery, it must be recharged
within one month.Check if the unit is turned off when storing it, so as to avoid
battery over discharge.
