Wow and flutterUnmeasurable (less than ±0.001% W. peak) 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). When using the rechargeable battery (fully charged) included with the unit When using one, commercially avail- able, high capacity, ÒAAÓ size (LR6), al- kaline battery (The rechargeable bat- tery is in the unit, discharged.)
