NOTE
The recharging time may vary according to the ambient
temperature and power source voltage.
CAUTION
When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
4. Disconnect the charger’s power cord from the
receptacle.
5. Hold the charger
fi
rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
CAUTION
○
If the battery is charged while it is heated because it has
been left for a long time in a location subject to direct
sunlight or because the battery has just been used, the
pilot lamp of UC18YFSL charger lights for 1 second,
does not light for 0.5 seconds (o
ff
for 0.5 seconds), or
the charge indicator lamp of UC18YSL3 charger lights
for 0.3 seconds, does not light for 0.3 seconds (o
ff
for 0.3
seconds). In such a case,
fi
rst let the battery cool, then
start charging.
○
When the pilot lamp or charge indicator lamp
fl
ickers (at
0.2-second intervals), check for and take out any foreign
objects in the charger’s battery connector. If there are no
foreign objects, it is probable that the battery or charger
is malfunctioning. Take it to your authorized Service
Center.
