Generally, isolate the cause by the following procedure:
A possible cause is that the wireless connection is not in an open state. Set the wireless connection to a waiting state in the system menu, and check again.
If there is no problem, isolate the cause by the same procedure as in the previous question.
A probable cause is that "MAC address filtering" is set to the access point or that unique IP addresses are not set.

Be sure to conduct a site survey before installing a wireless Handy Terminal.
You can make the BT switch between access points more quickly by increasing the roaming threshold on the "213. Connection Parameters" screen on the BT system menu. However, frequent switching between access points may make the battery power be consumed more quickly, and communication may be delayed when the BT switches. We ask that you perform sufficient on-site tests where you will use the BT.
