Operation Following Power Feeding to the Bluetooth
Terminal
Because cordless terminals use radio transmission between their Bluetooth
Bluetooth ® handset, they may take about 15 seconds after the line cord is installed into the
Bluetooth ® cradle before calls can be made between the Bluetooth
handset.
If the Bluetooth ® handset goes off- hook or the Conference or Talk key is pressed in the
meantime, the error tone "pi-pi-pi-pi" may sound without a wireless (line) connection being
established.
® handset always clean. Wipe
