The battery is a lithium ion battery. Use the special battery charger (SM-BCR1) to recharge the battery. Never use any other battery

charger to recharge the battery. If this is not observed, explosions or fire may result.

$ Storing the battery

When storing the battery away, remove the battery from the system and install the terminal cover first.

Terminal cover

• If the battery is stored away while the battery charge is 50% or higher (the indicator is illuminated green),

the battery will last longer.

It is recommended that you check the condition of the battery about once every half a year.

• If the battery is stored in cold locations, the performance of the battery may drop and the length of time that it can be used may

become shortened.

$ Battery life

• The battery is a consumable item. The battery will gradually lose its capacity for charging after repeated use and after time has

passed. If the length of time that the battery can be used becomes extremely short, it has probably reached the end of its life,

and so you will need to purchase a new battery.

• The life of the battery will vary depending on factors such as the storage method, the usage conditions, the surrounding

environment and the characteristics of the individual battery pack.

$ Guide to charging time

The charging time is approximately 1.5 hours.

(Note that the actual time will vary depending on the amount of charge remaining in the battery.)

Electrical contacts

Do not modify or damage these, otherwise problems

with operation will result. Take proper care when

handling the battery.
