Notes:
 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.
 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.
 The display can be scrolled up or down, from Channel 1 (1CH) to channel 9 (9CH), by using the [FEED]
or [RESTART] key.
 Pressing the [PAUSE] key causes the printer to perform a carrier sense again. To exit a carrier sense,
press the [FEED] or [PAUSE] key.
 When the RFID module type is set to "NONE" or a communication cannot be established, a message,
"NO RFID MODULE", is displayed.
 When the RFID module type is set to except U4, a message, "NOT AVAILABLE" is displayed.
 When the RFID module type is set to U4 but effective data cannot be obtained, a message, "NO
RESPONSE" is displayed.
 If the RFID module's country setting is not specified (user-inaccessible setting), an "RFID CONFIG
ERR" message is displayed.
