Precautions for Use
Use batteries
At the sametime, can not use different styleor different
capacitance batteries. Andonly charge the rechargeablebatteries.
Avoiding condensation problems
As much aspossible, avoid sudden temperature changes. Donot
attempt to usethe drive immediately after moving itfrom a cold
to a warmlocation, to raising the room temperaturesuddenly,
as condensation may formwith in the drive.If the temperature
changes suddenly while usingthe drive, stop usingit and take
out batteries forat least an hour.
Storage
When long timeno use,must take out the batteriesto avoid
destroying the device.

Charge
The instrument hasa charging function. When use rechargeable
batteries and alow battery indication shows on theinstrument, you
should promptly shutdown it and recharge. Long timeundervoltage
will shorten the lifetimeof the rechargeable battery.
Connect theAC adapter to the device correctly, it can charge
Automatically. Besides,computer USB port can also beused for
charging. The batteryremaining indicator keeps flashing during
charging. It will stopwhen the charging isfinished. The battery
has finished thefast recharge and can be useddirectly. If you do not
stop recharging atthis time, the in strument willcontinue the trickle
charge state, usingsmall current to supply natural discharge.But this
process is not morethan 48 hours.
The instrument canstill be used while charging. Butdo not plug in
the ACadapter when it is not rechargeablebattery inside, or it will
cause a hightemperature and combustion, even explosion.
