Operating precautions

Operate this printer in an environment that meets the follow-
ing requirements.
Temperature:
When charging: 5 - 40 °C/41 - 104 °F
Humidity:
(Maximum wet-bulb temperature: 27 °C/81 °F)
Do not operate or store this printer in a location exposed to
extremely high or extremely low temperatures, extreme
humidity, extreme dust, or extreme vibrations, otherwise
the printer may be damaged or malfunction.
If condensation occurs, allow it to dry naturally before
operating the printer.
Due to the characteristics of batteries, even though the
battery is fully charged, using them in locations at low tem-
peratures greatly reduces the number of prints possible.
The AC adapter case and the printer may become warm
while the printer is charging or printing. This does not indicate
a malfunction.
When the printer is not used, unplug the power supply plug
from the electrical outlet.
Do not block the paper output slot.
If the AC adapter connector or USB port becomes dirty, it
could result in faulty connections or charging. Periodically
clean the connector and port with a dry cotton swab.
When cleaning the printer, use a soft, dry cloth. Do not use
benzene or paint thinners, otherwise the printer may become
discolored or deformed. (
When using optional accessories, use them as described in
their instruction manuals.
Use thermal paper with this printer. If printed text is written
over or stamped, the text may disappear or become discol-
ored. In addition, it may take some time for the ink to dry.
Do not touch the printer with wet hands.
