How to use properly
●
In some cases, this command will not indicate 0% even though there are no Tags. Be sure take
this into account when determining the presence or absence of Tags.
●
The EAS Check Command works as a repeat command. After this command is sent once, only a
response will be returned. To discontinue transmission of this command, you need to use the Stop
Command (refer to ST Command in 5-5-1).
