The AX-Edge uses 8 AA rechargeable batteries only. This model will not power up with other types of AA batteries. Also note that the AX-Edge does not charge batteries, so you will need to use a separate battery charger.
Use this procedure to check the remaining battery life:
1. Hold down the SHIFT button and press the FAVORITE BANK button.
The bank/number display shows the remaining battery charge as 0–100 (%), and the LCD display shows the BATTERY INFO screen.
2. To exit, hold down the SHIFT button and press the FAVORITE BANK button.
Note: You can also access the BATTERY INFO screen from the MENU.
* The battery charge indication is only an approximation.
* While the AC adaptor is connected, the displayed value will always be “100.”
Low battery indication
When the battery charge runs low while the AX-Edge is operating on batteries, the decimal point in the lower right of the bank/ number display is lit. Replace the batteries as soon as possible. If you continue use, the decimal point changes from lit to flashing, and the display indicates “Charge Battery.” Stop using the AX-Edge, and replace the batteries.
Note: If you continue use after the decimal point starts flashing, the display indicates “Battery Low!” (the bank/number display indicates “Lo”). Further operation will be impossible, and the power turns off automatically.
