Charging the battery pack
The battery pack is not charged at the time of purchase and therefore needs to be charged
before use. Always use the supplied AC adapter/charger to recharge the battery pack.
Follow the procedure below to charge the supplied battery pack or a new UR-121 battery pack
used for the first time, or to recharge a battery pack that has become low in charge.
1
Remove the protective cover from the battery pack.
2
Insert the battery pack into the AC adapter/charger.
1 Orient the battery pack as shown in the figure on the
right, align the j marks on the sides of the battery
pack and AC adapter/charger, and insert the battery
pack in the AC adapter/charger.
2 Push in the direction of the arrow.
3
Insert the supplied power cord into the socket on the
AC adapter/charger.
œ Insert the power cord straight and until it is fully seated.
4
Plug the power cord into a power outlet (AC 100 to
240 V).
œ Charging will start automatically.
œ During charging, the BATTERY CHARGE lamp will
light red.
œ Charging will take approximately 120 minutes.
œ When charging is completed, the BATTERY CHARGE
lamp will turn off.
NOTE
œ Recharge the battery pack just before use or on the day before use. If charged and left unused,
the charge will slowly leak reducing the time the battery pack can be used.
œ Avoid storing the battery pack with it near full charge. It is recommended to store the battery
pack when it is near fully discharged.
œ If the battery pack is completely discharged, it may become unable to be recharged again. To
avoid this, charge the battery pack for at least five minutes every six months.
