Sometimes I hear 3 quick tones, one after the other, in the headset. What is causing this? How can I fix it?
If you are hearing some strange noises in the headset - typically 3 rapid tones in a row - It is likely that you have the wrong headset hooked up to the CT12. The correct headset has an LED at the end of the microphone boom. If you have the wrong headset hooked up and it does not have an LED at the bottom of the microphone boom, the headset will make 3 distorted sounds when the LED is supposed to flash.
