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 flickers 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, UC24YFA and UC18YRL 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.
