position?
If not, move it.
If the scanner is too close to or too far away from the RF tag, it
may fail to read/write from/to the RF tag. The distance may be
shorter in the write process than in the read process.
Is the RF tag inclined with respect to the antenna?
If so, make the RF tag surface parallel to the antenna surface.
If not, it may be read incorrectly or could not be read at all.
Are there any metal objects or equipment using
radio waves around the antenna?
If so, keep them as far away from the antenna as possible.
Are there any metal objects at/near the RF tag
attached area?
If so, keep the tag at least 15 cm away from them.
Is the RF tag or the RF tag attached area is wet?
If so, dry and then retry reading.
Is the PW LED lit?
If not, make sure that the AC adapter, which is included in the
package, is firmly connected.
Is the antenna port to be used selected?
Check the enabled port using the antenna port settings. Make
sure that the antenna is connected to the enabled port.

Precautions to be taken during RFID communication:
Even in the case of an RF tag conformable to the specifications described above, you may experience “unstable
communication” or “communication failure”.
To avoid such problems, carefully check the operation of the scanner with RF tags intended for use in the actual
operating environment.
Do NOT touch the antenna and its surrounding parts during reading by the scanner. This may result in poor
reception.
You may experience poor communication performance in the presence of any metal object.

Scanning Performance
The communication range based on our standard RF tag (Avery Dennison AD-229R6) is illustrated below.
The reference values given below were measured with the scanner and RF tag in the absence of any
object/substance that may affect radio waves around the scanner.
The reading range varies according to RF tag type and surrounding environment. It should be checked with
RF tags intended for use in the actual installation environment before use.

Writing performance
Tag memory writing requires more electric power than tag memory reading: If the same output level is set for reading and
writing, the writing range may be smaller than the reading range. Therefore, even if an RF tag is read successfully, a write
error may occur due to insufficient RF tag power. Check the operation of the scanner beforehand. If an RF tag is not
successfully written, adjust its position or change the communication range (output) setting to enables the write operation.
