When using the Standby button in the Roon App (found in Roon DSP) to place the RS150B into standby mode, the RS screen stays slightly backlit rather than going dark even though the unit appears to otherwise go into standby.
This only occurs when entering standby mode from a state where the RS LCD has been turned off during listening.
When using the Rose App remote control function, pressing standby while the RS LCD is off wakes the screen and then one has to press standby a second time. Not sure why this is necessary.
