OPERATING PRECAUTIONS
Please follow the precautions below to enjoy and maintain the full performance of the
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: 32 to 122F (0 to 50C)
· Relative humidity: 30 to 80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
same outlet with devices that generate noise.
DO NOT open the paper cover during printing.
DO NOT remove or reinstall the interface cable during printing or transmission. DO
NOT touch the connectors of the interface cable during printing.
DO NOT cut any cut paper or label paper with the paper cutter installed in the paper
outlet. Failure to follow this instruction may cause a cutting error or make the cutting
edge dull due to label paper adhesive sticking to the cutter.
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 thermal head, 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

- 10 -
performance.
The AC adapter, the battery charger and the battery pack may become warm when
in use. This is normal and is not a malfunction.
When the battery pack is used at low temperature, the length of time the printer can
be used may be shortened.
High-print-rate printing or using the printer under low temperature condition might
cause irregular printouts or generate loud noise. This is not a failure in the printer,
but an inherent paper phenomenon.
When using a Bluetooth interface, the radio environment around the printer may
cause a failure in communications. This is due to the specifications of Bluetooth,
which is a radio communications standard.
When handling this product, be aware of static electricity. If the static electricity is
discharged, this could cause communication failure. When this problem occurs,
disconnect the USB connector that is connected to the host device and wait few
seconds before connect it again.
Thermal Paper Handling
Store the thermal paper in a cool, dry, and dark place.
DO NOT rub the thermal paper with hard objects.
DO NOT leave the thermal paper near organic solvents.
DO NOT allow plastic film, erasers, or adhesive tape to touch the thermal paper for
long periods.
DO NOT stack the thermal paper with diazo copies immediately after copying or wet-
type copies.
DO NOT use chemical glue.
Always use the specified thermal paper. See Section 12, Options and Consumable
Parts, for details.
Precautions on Discarding
When discarding used printers, discard them according to the disposal regulations and
rules of each respective district.
