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).
When using the rechargeable battery
(fully charged) included with the unit
When using one, commercially avail-
able, high capacity, “AA” size (LR6), al-
kaline battery (The rechargeable bat-
tery is in the unit, discharged.)
