I have an echo in my headset
3 different base stations



Base 6000
To turn the volume of the speaker in the speaker pole down, start by opening the door on the right side. 9 dials appear. Turn the knob labeled "SPKR VOL OUTSIDE" to the left to make the sound softer.
Base 6100
Reset the base by pushing the button on the right hand side (preferably using a paperclip). Turn down the volume of the speaker in the speaker pole by pressing the button at the bottom right (menu). Go to Volume Adjustment. With In / Outbound audio you can lower the outbound volume.
