HELP!!! Digitrax Zephyr strange error message

I was running a train with my UT4 walkaround throttle, and I plugged in to a loconet port, then it wouldn’t aquire, and the status light on the throttle didn’t stay on, when I went to the Zephyr command station, it display read something that wasn’t an error message in the manual. EDIT: I just figured out what it said: -SLP

Can somebody help?

Thanks,

Never mind. I figured it out. Some of the loconet wires were twisted up and must have been touching. You can delete this, Bergie.
