  Edwin ThompsonAug 18, 2025
  If your Tone Commander Telephone is locked up, first press the SETUP key to display the Setup Menu. Then select ADMIN, press the MORE4 key, select RESTART, and choose YES. This will cause the telephone to attempt re-initialization with the network. If the Setup Menu does not function, disconnect and reconnect the line cord or local power supply to cycle power on the phone.

  Shawn TurnerAug 20, 2025
  If your Tone Commander Telephone display is blank and there are no lit LEDs: * For an 8610T or 8620T, verify connection to an external NT1 and verify power connection to the NT1. * For an 8610U or 8620U, verify connection to an external power supply and make sure the line cord is plugged into the U IN jack on the phone. If power is connected to the phone, but the display remains blank, replace the phone.
