Troubleshooting phones and base station

    'Not subscribed' message
    If you see 'Not Subscribed' on the phone, your phone is not subscribed to the base station. Use the following instruction to subscribe the device to the base station:

    1. On DP750/DP752 Base Station, press and hold Radio/Page button for about 7 seconds until radio LED starts blinking; or, access web UI > Status > DECT Status and press Subscribe button. 
    2. On handset, Press “Menu”  . 
    3. Use arrow keys to reach  “Registration”. 
    4. Navigate to “Register”, then press “Select” while the DP750/DP752 radio icon is blinking. 
    5. Select the corresponding base, and then press “Subscribe”. 
    6. DP720/DP722/DP730 handset will display Easy Pairing on the LCD and play an audible buzz when subscribed.

    If the device is subscribed and the calls are still not going through, make sure Do not disturb(DND) mode is not set on the phone.
    You can see if DND is enabled by checking for red icon in the left top corner. To disable it, hold down the mute button.
