  • Serial command 'freq' updates now return an error for invalid frequency arguments rather than silently clamping them.
  • When an invalid frequency is sent using the dweedle tone protocol an error message is now displayed to alert the user.
  • Fixed bug arising when the programmable switch was configured as an on/off switch. If so, the user could get stuck in an endless loop when attempting to turn off the device by pressing the power button on the keypad. The LCD would alternate between the "Powering down" page and the "Switch disabled" page.
