Nokia BH-606 用户手册

This device has an internal, 
nonremovable, rechargeable battery. Do 
not attempt to remove the battery from 
the device as you may damage the 
device. This device is intended for use 
when supplied with power from the 
following chargers: AC-3, AC-4, AC-5, 
and DC-4. The exact charger model 
number may vary depending on the type 
of plug. The plug variant is identified by 
one of the following: E, EB, X, AR, U, A, C, 
or UB. The battery can be charged and 
discharged hundreds of times, but it will 
eventually wear out. Recharge your 
battery only with Nokia approved 
chargers designated for this device. Use 
of an unapproved charger may present a 
risk of fire, explosion, leakage, or other 
hazard.

If a battery is being used for the first time 
or if the battery has not been used for a 
prolonged period, it may be necessary to 
connect the charger, then disconnect and 

reconnect it to begin charging the 
battery. If the battery is completely 
discharged, it may take several minutes 
before the charging indicator light is 
displayed.

Unplug the charger from the electrical 
plug and the device when not in use. Do 
not leave a fully charged battery 
connected to a charger, since 
overcharging may shorten its lifetime. If 
left unused, a fully charged battery will 
lose its charge over time.

Always try to keep the battery between 
15°C and 25°C (59°F and 77°F). Extreme 
temperatures reduce the capacity and 
lifetime of the battery. A device with a 
hot or cold battery may not work 
temporarily. Battery performance is 
particularly limited in temperatures well 
below freezing.

Do not dispose of batteries in a fire as 
they may explode. Batteries may also 
explode if damaged.
