Auto connection to the cellular phone 
After registration, your cellular phone is connected to 
the base unit. If you move the cellular phone out of 
base unit range, the cellular phone is disconnected 
from the base unit. This feature allows the base unit 
to try to reconnect the cellular phone at regular 
intervals when it returns within base unit range. You 
can set the interval. The default setting is “
1 min”. 
Important: 
•  When you are using a cellular line or a Bluetooth 
headset, the base unit loses its connection from 
other Bluetooth devices (cellular phone or 
headset). To automatically resume the connection 
to cellular phones, leave the auto connection on. 
•  Some cellular phones lose connection after usage, 
please check the specification of your cellular 
phone for more details.
