What do the Lights or Buttons Mean on the S12? Where is the Compatibility Switch?

Updated by Hayden Everly on Mar 2, 2023

(DISCONTINUED)

The three lights on the S12 base are from L to R are:

Headset indicator light - if it’s on, the headset is on

Power indicator light - if it’s on, the S12 has power

Mute indicator light - if it’s on, the user is muted

Buttons and dials:

On the front of the S12 base

- The button on the left is the headset button - use this to access the call in the headset

- The dial in the center is the incoming volume control

- The button on the right is the mute button - use this to mute the user

On the left of the S12 base

- This is the Compatibility Dial (1 or 4 are usually the best settings)

Here is a loose guide to compat:

1- most phones

2- Definity phones

3- Merlin Phones

4- GE 2-9450 phones/Cisco 7900

5- Siemens phones

6- NW Bell phones

On the right side of the S12 base

- The dial will fine-tune the outgoing volume

- The two dots are the master outgoing volume selectors - the small one is quieter, the large one is louder
