The back-lights on the Perform-V are somewhat bright and intense. Is there a way to adjust this brightness?
Yes, with the most recent firmware update (version 1.0.06 build 79) there is! Connect to VoiceSupport 2 and update your unit. Once the update is finished, press the SET button once until green lights appear in the LED ring around the Control Knob. You can now turn the knob to adjust the brightness of the buttons up or down. To exit this mode, press SET again or just leave it for a few seconds and it will automatically exit.
