Battery life
lThe 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.)
lThe volume level is set at ÒVOL 15Ó.
lThe LED is set at ÒLIGHT OFFÓ.lOperable duration with a commercially available battery varies depend-
ing on its maker, type, and conditions of use.
lÒFully chargedÓ means that the charging is complete after approximately
3.5 hours since the remaining amount of the battery is reduced to Ò Ó
(1 bar).
