POWER LEVEL 18
Radio output power level setting menu is displayed.
When the value is “9”, the power is the weakest, and when “18”, the power is the strongest.
The factory default setting is “18”. The optimum value differs depending on the tag types.
Usually, it is not necessary to change this value but changing the value may be able to
increase the number of successful read/write times.
Set the power level with the
[FEED]
or
[RESTART]
key.

AGC THRESHOLD 0
[PAUSE]
AGC threshold setting menu is displayed.
When the obtained gain of an RFID tag is lower than the AGC threshold, the tag is considered
as an error tag even if a data write succeeds.
When the AGC threshold is set to “0”, all tags are writable.
When set to “8”, for example, only tags with the AGC threshold level of 9 or greater are
writable. The optimum value is different depending on the tag types. The factory default is 0.
Set an AGC threshold with the
[FEED]
or
[RESTART]
key.
Press the
[PAUSE]
key.

Q VALUE 0
[PAUSE]
Q value setting menu is displayed.
In the case multiple RFID tags are read at the same time, this menu is useful to pinpoint a
target tag.
Set the Q value to “1” or greater (2 is recommended.) with the
[FEED]
or
[RESTART]
key. Q
value “0” causes the tags to interfere with each other and disables proper data write.
When a Q value is set, set an AGC threshold for data write and an AGC threshold lower limit for
retry, also. Setting all these values enable writing data to a tag placed just above the antenna.
(For details, refer to Section 4.23.5 AGC Threshold Setting.)
The factory default is 0.
