3. Battery Operation & Recharging
Automatic Battery Monitoring & Recovery System (ABMR)
The main amplifier is equipped with an auto battery monitoring and recovery system. This continuously monitors the battery
and will automatically turn-off the amplifier completely if the voltage drops to a dangerous level, which might harm
the battery. The system can instantly recover by switching on the supplied AC/DC adapter. When the low-battery LED
illuminates, the built-in battery needs to be charged immediately. Plug in the AC/DC adapter to input jack on the front
panel. The charge LED will illuminate and will automatically turn off when the charging completed in approx. 10h. Continue
to charge some extra hours to ensure battery fully charged.
4. Important Notes
-
The impendance of the external speaker should be greater than 16Ω.
Do not use an AC/DC adapter other than that supplied otherwise guarantee void.
Please do not use a fuse other than the specified rated one of 250V/5A.
Charging should be done at regular intervals to conpensate for natural discharging.
