3-4 Charging the Battery Pack
Be sure to read the following precautions before starting charging.
■
Charging precautions
●
When using the battery pack for the first time
•
First charge the battery pack.
•
The battery pack is not charged at the time of purchase.
•
Carefully read the instructions shipped with the battery pack before use.
●
Charging precautions
•
When charging the battery pack, do not place any cover over the main unit,
station, or printer. If a cover is used, the heat generated by the main unit,
station, or printer during charging may lead to fire. In addition, the
additional load due to the covering will reduce the service life of the battery
pack.
•
When charging is complete, the battery pack and the grip of the main unit
will be warm. This is normal.
•
Once the battery pack is charged, do not recharge it again without operating
the instrument, as this will lead to deterioration of the battery. If the battery
has sufficient remaining charge, the station will not recharge it.
•
If the charge lamp on the station flashes during charging, there may be a
problem with the charging. Follow the steps described later under “Check on
Flashing of the Charging Lamp.”
(See “10
-
2 Station (Troubleshooting)”)
•
The main unit or printer can be removed from the station and used before the
charging is completed.
●
Precautions on contacts
•
The charging may fail if the contacts are dirty.
•
Be careful not to touch the station contacts (recessed parts), main unit
contacts (pins on the front of the main unit), and printer contacts (side pins).
Also, do not touch the contacts (plates) of each battery pack.
•
If the contacts are touched or dirty, turn off equipment, and wipe them clean
with a dry cloth.
CAUTION
•
Only use the RT-121 battery pack, which is our designated lithium ion battery.
Use of any other battery voids the operation warranty.
•
Never disassemble or modify the battery pack.
•
Never short-circuit the terminal of the battery pack. Otherwise, heating may
occur, leading to burn injury or a fire. Also, keep metal objects (coins, paper
clips, etc.) away from contact with the terminal area.
