2-4 Checking the connected pairs
Checking the connection pairs may be necessary in the environment that multiple HR-51 and

munication unit is connection-established with HR-51, use this function.
■ How to check the connected pairs
Press the “Reader search button” of the communication unit HR-UC51 while the connec-
tion between HR-51 and HR-UC51 has been established.
The paired HR-51 sounds a buzzer.
