Turn the ringer off

Hi Angie.

The manual for this phone can be viewed here:
http://cdn-media.vtechphones.com/ecp/documents/product_Product/1681/UserManual/6351/ls6425-3_manual_i3.pdf
On Manual Page 20 / pdf page 23, it says that if the ringer is muted for a single call, that it should work again the next time someone calls.

However. page 57 notes that the base ringer volume can be set between 0 and 6, so it's possible your ringer volume is not technically muted, but just turned all the way down.

Manual page 62/pdf 67 has a half-page list of other reasons that the ringer might not ring. (It can also be turned off, and there are different adjustments for both the phone and the base unit.

Hoing this lets you figure it out!

With many VTech phones, you simply press the down-arrow or - key while the phone is in standby mode.

Enter the model of your VTech phone into the search box at http://www.vtechphones.com/support/general/manuals to download a copy of the manual.

Since you neglected to specify the model of your VTech 5.8GHz phone, I can only direct you to enter it into the search box here to download a copy of the manual.

Welcome to FixYa!

The base ringer is dependent to your handset ringer. If you lower the volume or turn off the handset ringer, the base ringer will follow.

Thank you for using FixYa.

Have a great day.

For this,check for a reset button below the main unit or the handset. This would reset your button,refer to your user manual on how to set it up.

You can download the manual from the manufacturer's web site at

Does your handset have a PROG button? Press that, then press the VOL+ button until you come to RINGER VOL: OFF. Press SELECT button, then use the ^ (VOL+) key until you get the desired volume level. Press SELECT again, then OFF. You're good to go.

The VT-9118 can use one of 4 different ring tones, and can be turned off. 

To reset your ring tone: 

1. Remove the handset from the base. 
2. Press PROG. You should hear a single short beep.
3. Press #.  You should hear a single short beep. 
4. Press a number 1 through 4. You should hear a long "ring" tone (it might be startling!). You can try other numbers from 1 to 4 to hear them all.  
5. Press MEM to confirm your ring. You will hear a medium beep. 
   

To turn the ringer off, follow the same instructions, but choose number 5. 
Hope this helps you. If you need for information, you can download the user manual from http://www.vtechphones.com/docMgt/public/art/313/vt9118.pdf
