The KAT500’s microcontroller operates whenever DC power is applied. LEDs and

From the KAT500 manual:
"Idle Sleep
In some installations a 28004.5 MHz signal may be heard from an oscillator in
the KAT500. If this is an issue, you can shut it down when it is not needed.
Click on Idle Sleep to put a check in the radio button. The oscillator will
stop running shortly after
When I use the KAT Utility to power down the KAT500, anyone know how much
current it consumes in this sleeping mode? I ask because I was surprised that I
had a dead battery this morning after a week or so of non-use (battery is a
rechargeable Lipo so no problem) but I was wondering how "asleep"
