  • As someone else noted, the beep on this unit is REALLY loud. If you open it up, you can replace the piezzo’s current limiting resistor R31 with a higher value resistor to lower the volume. I swapped the factory 55 ohm resistor for a 330 ohm resistor and now I’m no longer annoying everyone in the building.

    This is a super easy mod, but don’t attempt it unless you have a second soldering iron!
