Notice on RF tag reading/writing
・
Radio wave is used when reading/writing RF tag. Therefore, the peripheral metallic objects and
devices using radio wave (e.g. mobile phone, ham radio, and microwave oven) may deteriorate
the reading performance of the scanner. When using the scanner, keep the above mentioned
items as far away as possible.
・
When two or more RFID devices are used closely in a row, the scanner may have difficulty in
reading or cannot read codes due to interference. Keep each device away in the sufficient
distance.
・
Inconsistency of resonance frequency caused by an object with RF tag may make it difficult to
read the tag. Select RF tag with less inconsistent frequency and confirm the operation in
advance.
・
If the scanner is continuously used for reading/writing RF tag, the RF tag antenna may be heated.
Do not touch the heated RF tag antenna. Doing so for a long time may cause low-temperature
burn.
If the scanner is used for reading/writing RF tag for a long time continuously, it may operate
slowly or cannot read the tag smoothly due to the protection from heating of internal parts. This
may not cause a problem. If the sufficient reading performance is required, however, stop
emitting the radio wave, and retry the operation a little later.
・
If the scanner is used under the circumstances at the high temperature for a long time
continuously, it may operate slowly or cannot read the tag smoothly due to the protection from
heating of internal parts. This may not cause a problem. If the sufficient reading performance is
required, however, stop emitting the radio wave, and retry the operation a little later. To take the
reading performance fully into account, use the scanner under the circumstances at the normal
temperature.
・
If the scanner is used under the circumstances at the low temperature (below 0°C), use the large
capacity battery (BT-SP1L).
・
If the scanner is used under the circumstances at the especially low temperature (below -10 °C.
e.g. in the refrigerated warehouse), power the scanner ON at the normal temperature in advance
and then take it there. Powering ON the scanner at the low temperature may interrupt the
operation.
・
If the scanner is used under the circumstances at the low temperature, it may operate slowly or
cannot read the tag smoothly due to the characteristics of a battery. The operable time may also
be extremely reduced. Confirm the operating condition in advance to use the scanner at the low
temperature.
・
If the communication with the host terminal is disconnected during the RF tag reading, the
scanner continues the RF tag reading as the batch mode and accumulates data in SP1.
Accumulated data will disappear when the battery level is specially low. Immediately reconnect
to the host terminal and pick up data. Never remove a battery during the batch mode.
・
If the scanner is charged during RF tag reading/writing, communication with the RF tag will be
interrupted. If the charging is discontinued, communication with the RF tag will resume.
