2. Insert the battery into the charger
Insert the battery firmly, until it contacts the bottom of
the charger compartment.
CAUTION
If the battery is inserted in the reverse direction, not
only recharging will become impossible, but it may
also cause problems in the charger such as deformed
recharging terminal.
3. Charging
When inserting a battery in the charger, charging
will commence and the pilot lamp will light up
continuously in red.
When the battery becomes fully recharged, the pilot
lamp will blink in red (At 1-second intervals) (See
Table 1).
(1) Pilot lamp indication
The indications of the pilot lamp will be as shown in
Table 1, according to the condition of the charger or
the rechargeable battery.
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 up green. In
such a case, first let the battery cool, then start
charging.
When the pilot lamp flikers in red quickly (at 0.2-
second intervals), check for and take out any foreign
objects in the charger's battery installation hole. 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 confirm that the battery being charged
with UC14YFA and UC24YFA are 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.
Malfunction in the battery
or the charger.
The battery temperature
is high, making
recharging impossible.
