● 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.

Table 1

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.
