(green) will light up.
Even if you insert the
battery pack, the charging
status lamp (green) will not
light up.
The charger enters a
protection standby state
during charging.
(The orange lamp blinks
slowly.)
Note
• Request repair if the following abnormality is found in the battery charger.
ｰ Even if you insert the power plug into an outlet, the charging status lamp will not light up.
ｰ When you insert the battery pack, the cooling fan does not start running.
ｰ Just after charging starts, the charging status lamp does not light up or blink. (Both the green and
orange lamps are not lit.)
ｰ Even in 1 hour or more after the "protection standby state" (orange: blinking slowly), the charger

Possible cause
This is because it takes time to
detect a fully charged state.
There are some foreign bodies
on the contacts between the
battery charger and the battery
pack.
The battery pack temperature
has reached 60 °C (140 °F) or
above.
The battery pack temperature
has reached -10 °C (14 °F) or
below.
- 108 -
Action
After a while, it will enter a
full charging completed state
(green: blinking fast).
Remove the foreign bodies.
Charge it in a place with an
ambient temperature of 5 °C
(41 °F) to 40 °C (104 °F). If it is
being charged in a place with
5 °C (41 °F) to 40 °C (104 °F),
keep charging it as it is. If
the battery pack temperature
reaches the temperature
suitable for charging, charging
will start automatically.
