interference.
11. Two sealed lead-acid batteries with automatic charging design.The charger will be
activated immediately when AC power is plugged in,and AC power switch is in "ON" .
12. Two rechargeable batteries with 12V/5Ahr capacity each that could be used over 3.5
hours with in general volume & over 7.5 hours with low volume.
13. Uninterrupted power supply (UPS) design that will automatic switch to DC battery
without any effect when pulling out the AC power cable.
14. Two-steps LED charger indicator (Red and Green LED) with low voltage detection. It
would flash red light when charging, and light red when full charged, and would light
green when the voltage is normal, and flash green light under the low voltage.
15. Independent power switch for CD/MP3 player that could extend the battery using time.
16. Removable battery
17. Optional US-8001DB equipped with detachable BNC antenna.
Notice:
1. Please charge the rechargeable batteries more than 8 hours for first time operation.
2. Please refresh the batteries every three months when not using. The batteries will be
damaged if left unused for a long time. (over three months)
