OPERATING PRECAUTIONS
Please follow the precautions shown below to ensure full functionality of the printer and thermal paper.

■ Printer Switch the power off when not in use.
 DO NOT give a shock intentionary by dropping or hitting the printer. The printer with a rubber
cover has an excellent structure against impact on each surface. However, it may be broken
depending on the surface conditions, the angle of fall or the degradation state of the printer, and soforth.
 Give attention to ambient temperature and humidity during use of the printer. Proper operating
environment is as follows:
Ambient temperature: -15 C to 50 C / 5 F to 122 F
Relative humidity: 10% to 85%RH (no-condensing) DO NOT set/put the printer near any device that generates strong electromagnetic fields, like a
motor in a copying machine.
 DO NOT open the paper cover during printing.
 DO NOT remove or reinstall the interface cable during printing or transmission. DO NOT touch theconnectors of the interface cable during printing.
 NEVER close the paper outlet port or press down the paper which came out. If not, it might cause
paper jam.
 Cut only a part of liner with the paper cutter attached to the paper outlet. It may cause a cutting
error or make the cutting edge dull due to label adhesive sticking to the cutter if cutting a part oflabel sheet.
 Remove the battery pack, when you do not use the printer for long periods of time. If not, it might cause
excessive discharge and then will not allow you to use the printer even after it is charged.
 Clean the printer exterior with a soft, lint-free cloth where necessary. DO NOT use alcohol andother solvent.
 Before use, always clean the terminals using a dry, soft, lint-free cloth. If the terminals are dirty, it
may not allow you to ensure proper contact.
 Be sure to wipe the printhead with a soft swab, etc. when cleaning the thermal printhead.
 Unplug the AC cable except when using the AC adapter.

- 12 -

 When storing the battery pack for long periods of time, keep it in a cool place. If possible, avoid
long-term storage in the fully charged state. It may affect the battery life.
 Clean the terminals of the battery pack regularly (wipe them with a dry cloth).
 In order to fully demonstrate the performance of the battery pack, charge the battery at room
temperature and the temperature of the battery pack ranging from 0 C to 40 C / 32 F to 104 F.
 Clean the terminals of the dedicated charger regularly (wipe them with a dry cloth).
 DO NOT connect the AC cable to the power supply wall socket which was already connected toany other devices which generate noise.
 High-print-rate printing might cause irregular printouts or generate loud noise. This is not a failurein the printer, but an inherent paper phenomenon.
 Always use roll paper whose width is at least 4 mm wider than the print width.
 To ensure the bar code printing quality, parts having high printed ratios may be light at a lowtemperature.
 When using a Bluetooth interface, the radio environment around the printer may cause a failure incommunications. 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 case communication failure. When this problem occurs, disconnect the USB connector thatis connected to the host device and wait few seconds before connect it again.
 If dew condensation occurs on the roll label, the peel function may not work well or paper jam mayoccur. Avoid drastic changes in the environment.
