Power consumption: 7 W (AC adaptor) | |
Output | RMS; 20 mW (10 mW + 10 mW) |
power: | (0.2% T.H.D.) |
Charging | Approx. 3.5 hours (90 %) |
time: | Approx. 5.5 hours (fully charged) |
| (When using the AC adaptor included with the unit) |

●The continuous recording time is for analogue inputs when the volume level is set to “VOL 0”.
●The continuous play time shows the value when the volume level is set to “VOL 15”.
●The above values are the standard values when the unit is charged and used at an ambient temperature of 20°C (68°F).
●The operating time when using an alkaline battery may be dif- ferent, depending on the type and manufacturer of the battery, and on the operating temperature.
