Support

Technical support for all GRT products is provided at no charge, for all instruments produced over the last 26 years, for original and future owners. While we are happy to assist our customers with questions about our equipment, often the information we provide over the phone is also available in our installation manuals and other resources on our website.

We ask that before you call, please use the materials we provide on the website to make your best reasonable attempt to answer your question.  If this proves insufficient, we will do our best to answer your tech calls during support hours.  Messages left during support hours will be answered as soon as possible.  

When calling, please have the  serial number and software version of your unit handy.  We often ask for this during troubleshooting, so it might save you a trip to the airport.

Tech support is available Monday through Friday from 10 AM to 12 PM and 2 PM to 4 PM  EDT
