If you're getting an "Out of Range" error on your VTech or AT&T cordless home phone, here are some troubleshooting steps to fix it:
1. Check the Distance & Interference
Move closer to the base station to see if the message disappears.
Cordless phones work within a limited range (typically 150–300 feet indoors).
Walls, furniture, and electronic devices (Wi-Fi routers, microwaves) can interfere. Try repositioning the base unit.
2. Power Cycle the Phone & Base
Unplug the base station from power for 30 seconds, then plug it back in.
Remove the handset battery, wait 15 seconds, then reinstall it.
Check if the handset reconnects.
3. Re-Register the Handset to the Base
If your handset has lost its connection, you may need to re-register it:
VTech Phones:
Press and hold the "Find Handset" or "Handset Locator" button on the base for 5–10 seconds.
Follow the on-screen instructions on the handset to reconnect.
AT&T Phones:
Press and hold the "Hold" or "Page" button on the base until the indicator light starts flashing.
Follow the handset instructions to re-register.
4. Check for Low Battery
A weak or old battery can cause connectivity issues.
Try charging fully or replacing the battery.
5. Reset the Phone System
Remove all power cords, batteries, and phone line connections for 5 minutes.
Plug everything back in and check if the issue is resolved.
6. Check for Frequency Interference
Cordless phones operate on 1.9GHz (DECT 6.0) or 2.4GHz / 5.8GHz frequencies.
If you have Wi-Fi routers, baby monitors, or Bluetooth devices nearby, try changing their channels or relocating the phone base.
7. Verify Phone Line Connection (If Using Landline)
Ensure the phone is properly plugged into the wall jack.
If using a VoIP service (e.g., AT&T U-verse, Xfinity Voice, etc.), restart your modem and check for service issues.
8. Factory Reset (If Available)
If all else fails, check the user manual for a factory reset option to restore the phone to its original settings. Some of the included model numbers are
