Operation Mode When Battery is Low
There are two operation modes for the printer when the battery is low. Change the mode depending on the
usage status.
Mode 1 (initial setting):
Continues printing until the remaining battery becomes approximately 0%. This is appropriate if you want to
maximize the battery operation time. However, the printer may stop during the printing or print quality may
decrease when the remaining battery becomes near 0%.
Mode 2:
Stops printing when the remaining battery becomes approximately 10%. This is appropriate if you want to avoid
that the printer stops during the printing.

When the amount of charge remaining in the battery reaches the L level, we recommend
replacing or charging the batteries.

When the amount of charge remaining in the battery reaches the S or E level, we recommend
replacing or charging the batteries.

The operation mode when battery is low is selectable with the customized value. To set the
customized value, see "Software Settings" on page 47 .

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 47 .

Before printing starts, the amount of charge remaining in the battery is detected, and the
display is updated after printing. The battery LED display does not detect the amount of
charge remaining in the battery in real time.
