Notes:
1. The left-most number indicates a channel number. The percentage means the availability of the channel,
which is determined by performing approx. 30 carrier senses. Thus, "100%" means that any other devices
do not use this channel.
2. The MAX column shows the value of the maximum radio wave picked up. The larger the value is, the
stronger radio wave source exists nearby.
3. The display can be scrolled up or down, from Channel 1 (1CH) to channel 9 (9CH), by using the [FEED] or
[RESTART] key.
4. Pressing the [PAUSE key causes the printer to perform a carrier sense again. To exit a carrier sense,
press the [FEED] or [PAUSE] key.
5. When the RFID module type is set to "NONE" or a communication cannot be established, a message, "NO
RFID MODULE", is displayed.
6. When the RFID module type is set to except U4, a message, "NOT AVAILABLE" is displayed.
7. When the RFID module type is set to U4 but effective data cannot be obtained, a message, "NO
RESPONSE" is displayed.
8. If the RFID module's country setting is not specified (user-inaccessible setting), an "RFID CONFIG ERR"
message is displayed.
