Access Password
You must specify the access password (8 hexadecimal digits) to the Reader/Writer to execute com-
munications commands for an RF Tag with a locked memory area. If you attempt to execute a com-
munications command without specifying the access password, a password error will occur.
• If the access password area in the memory of the RF Tag is not all zeros, the memory will be
locked.
• If the UII (EPC) area, TID area, user area, or access password area in the memory of the RF Tag
is locked, you must specify the access password to use write communications commands for the
locked area.
• If the access password area in the memory of the RF Tag is locked, you must specify the access
password to use a communications command (DATA READ) to read the area.

Transmission Time
You can specify the continuous transmission time to output radio waves continuously and the stop
time to pause the output when the Reader/Writer communicates with an RF Tag.
By stopping the transmission output at specific intervals, you can suppress the influence of radio
wave interference with nearby Reader/Writers.
