DO NOT cut except liner part of a label sheet with the paper cutter. This instruction may make the
cutting edge dull due to label sheet adhesive sticking to the cutter.
◆
The car charger is only for charging. Even if the car charger is connected to the printer, the printer
cannot print without the battery pack.
◆
Charging the battery pack by car charger is possible while the car engine is running or in accessory
position. Check the car battery remaining capacity is sufficient before using the car charger in
accessory position.
◆
After using the car charger, unplug the cigar plug from a car accessory socket.
◆
DO NOT print out during a vehicle driving. Ejected thermal paper may hinder a vehicle driving.
◆
DO NOT drop or insert any foreign objects such as a clip, a pin, or a screw in the internal parts or
slot of the products.
◆
DO NOT drop any liquid or spray a solvent to the products.
◆
NEVER push the switch on the operation panel using sharp object such as pen tip.

Make sure not to injure your body or other objects by the plate edge.
◆
Unplug the AC plug or cigar plug from an outlet or a car accessory socket when something goes
wrong with the printer, and remove the battery pack.
◆
NEVER disassemble the printer without a serviceman.
Precautions for Wireless communication
◆
When using Bluetooth interface, the communication may become unstable due to the influence from
any external radio waves. This is the specification of Bluetooth for wireless communication
standard.
◆
Bluetooth model uses 2.4GHz frequency range. Wireless LAN model IEEE802.11b/g/n uses
2.4GHz frequency range, and IEEE802.11a/n uses 5GHz frequency range. So if these models are
used around any equipment with the same frequency range such as wireless LAN or 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. In addition, shorten the
distance between the host device and the printer.
◆
When using Wireless LAN model IEEE 802.11a/n, the communication may stop temporarily before
outputting radio wave to the target channel not to affect the radar for weather, air traffic control or
others. This is the reason to detect those radar waves during a certain period. If detect other radio
wave during operation, it may change the target to other channel.
Precautions for maintenance
◆
Clean the printer case using soft, lint-free cloth. DO NOT use alcohol or other solvent.
◆
Before using, always clean the terminals using a dry, soft, lint-free cloth. When the terminals are
dirty, it may cause contact failure.
◆
When cleaning the thermal head, wipe the thermal head with a cotton swab or other soft material.
