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 the charger lights for 1 second, does not light for 0.5 seconds (off for
0.5 seconds). In such a case, fi rst let the battery cool, then start charging.
○
When the pilot 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.
○
Since the built-in micro computer takes about 3 seconds to confi rm that the battery
being charged with charger is taken out, wait for a minimum of 3 seconds before
reinserting it to continue charging. If the battery is reinserted within 3 seconds, the
battery may not be properly charged.
○
If the pilot lamp does not blink in red (every second) even though the charger cord
is connected to the power, it indicates that the protection circuit of the charger may
be activated.
Remove the cord or plug from the power and then connect it again after
30 seconds or so. If this does not cause the pilot lamp to blink in red (every
second), please take the charger to the Hitachi Authorized Service Center.
