Master Unit M&S System displays REL 5


This actually means RELS which stands for release. There is typically a bad room station that has a broken button, or button stuck. To troubleshoot, remove all black wires from the master unit. Any display of RELS or clicking sound should stop. Add back the black wires one by one until the issue of RELS occurs again. If so, do not attach this wire and hook up all remaining wires. If the user wants to know which room station this is, go from room to room and press the listen button. If the music is muted, the station is good. If the music continues, this is the bad room station. Unfortunately, these room stations are no longer available. Visit our website for replacements parts and products, or if you have more questions.

Why is the base station not working when the power supply is good?


It is highly unlikely that you will be able to buy just a new base station from the original manufacturer. If you are still covered by the warranty, return the unit and try to claim a brand new unit.
Try taking a call even though the red light doesn't work. Sometimes, the bulb can be faulty. This however, shouldn't prevent you from making a call

Roady 2 signal goes in and out....


We've been having the same problem with our Roady XT unit at the office. Sometimes I think it's possessed because it goes in and out, changes to the mute mode, and sometimes turns itself off. Just got another Roady XT unit today. It played fine, then went into the mute mode. Called XM and they told me to reset unit to factory default. It's fine at the moment.

Crackling coming from Velodyne DD-10 subwoofer


One of 2 things is going on.

First, the servo mounted in the driver may be going bad or is picking up some noise.

Second, Something in the amp section is going bad, hard to pinpoint the exact problem.

you say that it plays, so I tend to think it is the driver mounted servo unit.

If it is within the warranty time, take the unit back to the retailer you purchased it from, if not contact Velodyne for repair.

So call a factory authorized company and have it replaced.The warranty of a Sub Zero sealed system is full parts and labor for years 1-5 and parts only in year 6-12.
