(2) Regarding the temperature of the rechargeable battery.
The temperatures for rechargeable batteries are as shown in the table below, and
batteries that have become hot should be cooled for a while before being recharged.
(3) Regarding recharging time (At 68°F (20°C))
In approx. 60 minutes.
NOTE: The charging time may vary according to temperature and power source voltage.
4. Disconnect battery charger from the receptacle.
CAUTION:
Do not pull the plug out of the receptacle by pulling on the cord.
Make sure to grasp the plug when removing from receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out the battery from the battery charger.
CAUTION:
● When the battery charger has been continuosly used, the battery charger will 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 rechraged when it is warm due to battery use or exposure to sunlight,
the pilot lamp may light in green.
The battery will not be recharged. In such a case, let the battery cool before charging.
● When the pilot lamp flickers rapidly in red (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 UC 24YF 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.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been
used for an extended period is not activated, the electric discharge might be low when
using them the first and second time. This is a temporary phenomenon, and normal time
required for recharging will be restored by recharging the batteries 2 – 3 times.
