Notes on Use of Battery in US40a
NOTES:
• When the battery is charged sufficiently, do not install or remove the
battery pack from US40a if not required particularly. Failure to
follow this may cause the battery pack to be defected.
• Charge the battery as full as possible when charged. If you repeat a
small amount of charging/discharging many times in low remaining
battery status, some error may occur in the remaining battery level.
Proper Use of Battery
• To keep high display precision of the remaining battery level, refresh the battery
periodically.
• When US40a is not used for a long period, remove the battery pack with the remaining
battery level of about 50% and save it in a cool place. This can lengthen the battery life.
• When US40a is operated for a long time only by the battery, use the power saving feature
of US40a.
• The battery discharges naturally. It is recommended to charge the battery once for two to
three months even if US40a is not used for a long period.
