Battery charging error. You may need to replace the battery.
External power connected and there is no battery in the printer.
Here are some tips for extending the overall life of your battery:
• Never expose the battery to direct sunlight or temperatures over
50°C (122°F).
Only charge the battery inside the PB21/PB31 using a power
•
supply or in the 4-bay battery charger (Model AC18).
• Do not set the backlight to always on. The always on setting
disabled automatic power saving modes.
Here are some tips for extending the life of your battery between
charges:
• Press the Standby button to put the printer in Standby mode.
• Remove the battery from the printer if you will not be using it for
three days or more.
• Do not operate the printer when the ambient temperature is -20 C
(-4 F) or below. Using the PB21/PB31 in temperatures below
freezing reduces the overall battery life.
Remember that any rechargeable battery loses its ability to maintain a
charge over time. You can only recharge it a finite number of times
before you must replace it.
