Precautions for Use
Use batteries
At the same time,can not use differentstyle or different capacitancebatteries. And only charge the rechargeable batteries.
Avoiding condensation problems
As much as possible,avoid sudden temperature changes.Do not attempt touse the drive immediatelyafter moving it froma cold
to a warm location,to raising the roomtemperature suddenly, as condensation may formwith in the drive.If the temperature
changes suddenly while usingthe drive, stop usingit and take outbatteries for at leastan hour.
Storage
When long timeno use,must take out the batteries to avoid destroyingthe device.

Charge
The instrument has acharging function. When userechargeable
batteries and a lowbattery indication shows on theinstrument, you
should promptly shut down it and recharge.Long time undervoltage
will shorten the lifetimeof the rechargeablebattery.
Connect the AC adapterto the device correctly, it can charge
Automatically. Besides, computerUSB port can alsobe used for
charging. The battery remaining indicatorkeeps flashing during
charging. It willstop when the charging is finished. The battery
has finished the fastrecharge and can beused directly.If you do not
stop recharging at thistime, the in strumentwill continue the trickle
charge state, usingsmall current to supplynatural discharge. Butthis
process is not morethan 48 hours.
The instrument can stillbe used while charging. But donot plug in
the AC adapter whenit is not rechargeablebattery inside, or it will
cause a high temperatureand combustion, even explosion.
