How To Recharge Usb Device - Hitachi DS 18DBL2 Instruction Manual

English
Regarding electric discharge in case of new
batteries, etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an extended
period is not activated, the electric discharge might
be low when using them the fi rst and second time.
This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging
the batteries 2 – 3 times.
How to make the batteries perform longer
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a while.
CAUTION
● When the battery charger has been continuosly
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes
rest until the next charging.
● If the battery is charged while it is heated
because it has been left for a long time in a
location subject to direct sunlight or because
the battery has just been used, the pilot lamp
of UC18YFSL charger lights for 1 second, does
not light for 0.5 seconds (off for 0.5 seconds) or
the charge indicator lamp of UC18YSL3 charger
lights for 0.3 seconds, does not light for 0.3
seconds (off for 0.3 seconds). In such a case,
fi rst let the battery cool, then start charging.
● When the pilot lamp or charge indicator lamp
fl ickers (at 0.2–second intervals), check for and
take out any foreign objects in the charger's
battery installation hole. If there are no foreign
objects, it is probable that the battery or charger
is malfunctioning. Take it to your authorized
Service Center.

HOW TO RECHARGE USB DEVICE

WARNING
○ Prior to use, check the connecting USB cable for
any defect or damage.
14
Using a defective or damaged USB cable can
cause smoke emission or ignition.
○ When the product is not being used, cover the
USB port with the rubber cover.
Buildup of dust etc. in the USB port can cause
smoke emission or ignition.
NOTE
○ The time required for charging will be longer when
a USB device and battery are being simultaneously
charged.
○ There may be an occasional pause during USB
recharging.
○ When a USB device is not being charged, turn the
USB power switch OFF and remove the USB device
from the charger.
Failure to do so may not only reduce the battery life
of a USB device, but may also result in unexpected
accidents.
(1) Select a charging method
Depending on the charge method selected, either the
battery is inserted into the charger or the power cord
is plugged into an outlet.
○ Charging a USB device by battery (Fig. 9-a)
○ Charging a USB device from a electrical outlet
(Fig. 9-b)
○ Charging a USB device and battery from a
electrical outlet (Fig. 9-c)
