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).
