When it is used for the fi rst time or when it is not used for several days,
 The operating time might become shorter or the charging time might become longer.
 We recommend that you replug the connector into the vacuum cleaner to recharge the battery before use.
 When you insert the connector into the terminal of the vacuum cleaner, the battery indicator lights up.
 If you disconnect the AC adapter from the vacuum cleaner after the battery indicator turns off (indicating
that the battery is fully charged), and then reconnect the AC adapter to the vacuum cleaner, the battery
indicator turns on (indicating that the battery is being charged), but this does not indicate a problem with
the vacuum cleaner.
 While the vacuum cleaner is being charged, the vacuum cleaner or AC adapter might become hot, but
this does not indicate a problem with the vacuum cleaner.
 The vacuum cleaner will not operate even if the control buttons is pressed while charging.
 When charging the battery, make sure the ambient temperature is between 5˚C to 34˚C. Charging the
Note
battery in temperatures outside of this range might prevent the battery from being fully charged. As
a result, the battery might take a long time to charge, or you might only be able to use the vacuum
cleaner for a short time.
If you charge the battery in a hot or cold area for 3 hours or more, the battery indicator will blink rap-
idly (estimated twice per second). In this case, recharge it in place with an ambient temperature be-
tween 5˚C to 34˚C.
 If the battery indicator does not turn on, or it turns on briefl y and then turns off, remove the connec-
tor of the AC adapter from the vacuum cleaner and then insert the connector back into the vacuum
cleaner.
 Charging it near a radio might cause sound interference when the radio is in operation.
When charging the vacuum cleaner, plug the AC adapter into an outlet that is at least 2 meters away
from any radio equipment.
To prolong battery life
 Be sure to charge the vacuum cleaner after each use, even if you only used the vacuum cleaner for a
short period of time.
 If the vacuum cleaner is not to be used for more than a month, please fully charge the battery before stor-
ing it. Charging it once a year if the vacuum cleaner is not in use will prolong the battery life. (Storing a
depleted battery will deteriorate the battery performance and battery life.)
 If the vacuum cleaner stops in the middle of operation, because the battery has run out, you might still
be able to use the vacuum cleaner for a short while by pressing the control buttons. However, this type of
action is not recommended. Performing this type of action will shorten the battery life.
