RECHARGEABLE BATTERIES (NOT INCLUDED)
Prior to the use of a new unit, the rechargeable battery should be charged according
to the battery manufacturer's instruction. Before using the battery charger, read all
instructions and cautionary markings on the battery and the instruction manual.
After being stored for 60 days or more, the batteries may lose their charge. After
long periods of storage, batteries should be charged prior to use.
BATTERY CHARGING
(1) Plug the charger into any working 110 or 220/240v mains electrical outlet. The
use of any attachment not supplied with the charger may result in the risk of fire,
electrical shock, or injury to persons.
(2) Follow the battery manufacturer's instructions for charging time.
(3) After the battery manufacturer's instructions recommended charging time has
been completed, unplug the charger and remove the battery.
(4) Batteries should always be stored in a fully charged state. To ensure optimum
battery performance, follow these guidelines.
(a) Although overcharging the batteries for up to 24 hours will not damage
them, repeated overcharging may decrease useful battery life.
(b) Always store batteries in their charged condition. After a battery has
been discharged, recharge it as soon as possible. If the battery is
stored more than 60 days, it may need to be recharged.
(c) Do not short the terminals of the battery. This will cause the battery to
get hot and can cause permanent damage. Avoid storing the batteries
in your pocket or purse where the terminals may accidentally come
into contact with coins, keys or any metal objects.
(d) WARNINGS:
1. Do not attempt to charge any other types of batteries in your charger,
other than the nickel-cadmium rechargeable batteries. Other types of
batteries may leak or burst.
2. Do not incinerate the rechargeable battery as it may explode!
