CAUTION
● When the battery charger has been continuosly
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.
● 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 ikers rapidly in red (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.
