If the printer suspends printing because the battery remaining capacity becomes low, connect theAC adapter and resume printing or communication.

◆

DO NOT use the thermal head when it is wet. Doing so may damage the printer.

◆

Printing under low temperature environment or printing at a high print rate might cause unclear
printing or generate loud sound. This is not a failure in the printer but an inherent paper
phenomenon.

◆

Continuous printing with high print rate might cause temporarily stop printing by temperaturedetection of the printer. Printing resumes when the printer's temperature cools down. When thiserror occurs and "Data Discard Selection When Error Occurs" in the Function Settings is "Enable",the print data transmitted when an error occurs is discarded.

◆

In low temperature, the usable operating time of the printer may be shortened due to thecharacteristics of the battery pack.

◆

The indicator of battery remaining capacity shown in the POWER LED is for reference. The battery
level may be significantly changed depending on the printer operation, so charge the battery packbefore the battery becomes low.

◆

The battery pack should be charged at 0°C to 40°C (32°F to 104°F).

◆

The charging time depends on the ambient temperature and the voltage level of the battery pack.
Normally, when using the printer or the battery charger "PWC-A071-A1", it takes about 4 hours tocomplete charging after running down the battery pack. When using the quad battery charger"PWC-A074-A1", it takes about 5 hours.

◆

The battery pack, the AC adapter and the car charger may get a little hot when in use. This is normal
and not a malfunction.

property.

Precautions for Wireless communication◆

When using the Bluetooth interface, the communication may become unstable due to the influence
from external radio waves. This is based on Bluetooth specification which is a wirelesscommunication standard.

◆

The model with Bluetooth operates in the 2.4GHz frequency range. The model with Wireless LAN
IEEE802.11b/g/n uses 2.4GHz frequency range, and IEEE802.11a/n uses 5GHz frequency range.
So if this model is used around other wireless LAN or any equipment using the same frequency
range such as a microwave oven, radio frequency interference may occur, and the communication
may become unstable. When it happens, turn off the interfering equipment or increase the distance.
Alternatively, shorten the distance between the host device and the printer as much as possible.

◆

When using the model with Wireless LAN IEEE802.11a/n, the printer may stop communication
temporarily before outputting radio wave to the target channel not to affect the weather radar, airtraffic control radar or others. This is to monitor the presence of radar waves for a certain time. If theprinter detects radio waves such as radar during operation, it may switch to another channel.

Precautions for maintenance◆

Clean the products’ cases using a soft and lint-free cloth. DO NOT use alcohol or other solvent.

◆Before using, clean the terminals using a dry, soft, and lint-free cloth when they are dry. If theterminals are dirty, it may cause contact failure.

◆

When cleaning the thermal head, always wipe it with a cotton swab or other soft material.

◆

If the carrying case becomes dirty, clean it by a cloth which is moistened with water and wrung out
strongly.

◆

If the inside of the carrying case becomes wet, dry it before use.

9

Precautions for storing◆

Turn off the power when not in use.
In addition, when the printer is not used for a long time,
・Unplug the AC plug from an outlet.
・Remove the battery pack from the printer. If not, it will cause overdischarge, and the battery pack
will not be usable even after it is charged.
・Set thermal paper to protect the platen.

◆

When the printer is not used for a long time, store the battery pack in a cool place. Avoid long-term
storage in a fully charged state as much as possible because it may shorten the life span of thebattery pack.

 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 PVC film, erasers, or adhesive tape to touch the thermal paper for long periods.
