I turned my DB-150 on this morning and receiving several odd responses.
1) The DB-150 will beep intermittently. There are no patterns to the number of beeps or intervals between beep.
2) My DT-402 throttle will beep every time I turn the control knobs.
Any ideas will be helpful.
The DB-150 has an internal clock that runs down, I think meant to be a 'fast clock' for layout operations. The beep comes every 20-30 minutes in my own case. Also, you can turn the encoder knob beeps off if you select the option switch that your manual lists in one of the tables.
