・ 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.
・ "MAX 0011" means the value of the maximum radio wave picked up.
・ The display can be scrolled up or down, from Channel 1 (1CH) to channel 9 (9CH), by using the [UP]
or [DOWN] key.
・ Pressing the [ENTER] key causes the printer to perform a carrier sense again. To exit a carrier
sense, press the [CANCEL] key.
