Operation Mode When Battery is Low
The printer acts differently depending on the remaining battery charge and the operation mode 
when battery is low. 
The printer has two modes and is initially set to the mode 1.
Mode 1
*: Printing may stop in the middle.
 It is recommended to replace or charge the battery when the remaining battery charge
goes down to the level L.
 The remaining battery charge is detected before printing starts and the displayed
amount is then updated. The Battery LED does not indicate the remaining battery
charge detected in real time.
 The operation mode when battery is low is selectable with the customized value. To set
the customized value, see "Software Settings" on page 44.
 The buzzer beeps five times when the remaining battery charge goes down to the levels
L or S. You can disable the buzzer with the memory switches. To set the memory
switches, see "Software Settings" on page 44.
