Hello I have 4 pixie devices.  Two are right next to each other.  One of these two keeps going off-line every couple of days.  Then i have to manually press the button on the device to bring it back on-line?  How do i fix this annoying issue?  Thanks. Sang

Hello-  I have two new whisper devices. Both will not go into pairing mode.  Press power button six times and the light just blinks red on and quickly off. Press three times and same thing.
