For lower voltage battery operation, set the internal jumper terminal for battery
operation, and then connect external batteries.
Warning: If you have changed the internal jumper for low-voltage battery
operation, battery voltage must be within the range of 5.6 ~ 6.5 VDC. DO
NOT apply 12.0 V or severe damage will result, and the warranty will be void!
Note: There is no low battery voltage detector built-into the ARD9800.
