Battery life
● The above values are the standard values when the unit is operated hori-
zontally and charged at an ambient temperature of 77°F (25°C). (The
operable duration with the rechargeable battery will be shorter when the
unit is carried around.)
● The volume level is set at “VOL 15”.
● The LED is set at “LIGHT OFF”.
● Operable duration with a commercially available battery varies depend-
ing on its maker, type, and conditions of use.
● “Fully charged” means that the charging is complete after approximately
3.5 hours since the remaining amount of the battery is reduced to “
”
(1 bar).
