What to do if there is no dial tone on my Telkom OPTICON MICRO Telephone?
- MMary NguyenJul 29, 2025
If your Telkom Telephone has no dial tone, verify that the telephone line cord is correctly plugged into both the base and the telephone socket. Also, ensure the terminal is registered to the base. Check that the base is connected to the main power source and that the batteries of the handsets are properly installed. If the terminal isn't registered when you attempt a call, the display will show 'Out of Range?'.
