Discovery 655/665: How to Disable Digital Signal Processing (DSP)

The following article details how to disable the digital signal processing (DSP) feature on your Discovery 655/665 headset.
In order to disable the digital signal processing feature, you'll want to enable power-saving mode. Power saving mode temporarily disables the Digital Signal Processing (DSP) feature of the Discovery 655 and 665 headsets to provide a longer talk time.

To enable power saving mode, press 
both the volume up and down keys at the same time before you make a call. To re-enable DSP, press both the volume up and down keys at the same time. Power saving mode cannot be turned on while engaged in a call.
NOTE After you turn off the headset, DSP will be re-enabled the next time you turn it on.
