printer.
Using the Printer
Be careful not to drop or bump the printer on a hard surface.
DO NOT install the printer in direct sunlight or such areas. Suitable environment for
the use of the printer is as follows:
· Ambient temperature: 14 to 122
F (-10 to 50
C)

RH (noncondensing)
See the Technical Reference for details of applicable humidity at each temperature.
DO NOT install the printer near devices that generate strong electromagnetic fields
such as a copy machine.
DO NOT install the printer in a location that is subject corrosive gas or siloxane and
so on.
DO NOT connect the AC cables of the AC adapter and the battery charger to the

NOT touch the connectors of the interface cable during printing.
Switch the power off when not in use.
Clean the printer using soft, lint-free cloth. DO NOT use alcohol or other solvent.
Before use, always clean the terminals using a dry, soft, lint-free cloth. If the
terminals are dirty, it may not be possible to obtain proper contact.
When cleaning the TH, wipe the thermal head with a cotton swab or other soft
material.
Remove the battery pack from the printer if the printer is not used for a long time. If
not, it may cause overdischarge and shorten life span of the battery pack.
Store the battery pack in cool place. DO NOT store the battery pack for long time
with fully charged condition because it may shorten life span of the battery pack.
The battery pack should be recharged at 32 to 95°F (0 to 35°C) for optimum

The AC adapter, the battery charger and the battery pack may become warm when
in use. This is normal and is not a malfunction.
