Intercom between office and shop solutions? in Auto Repair Shop Management Help? Start Here Posted November 18, 2019 · Edited November 18, 2019 by rubberbroker Beginning the first of August, we purchased hand held radios (link attached) and for the small investment, introduced them to our team. We have some guys using the earpiece and others using handheld mics. We have worked with each other on radio etiquette and honestly, I can't imagine not having them. It has brought our 10,000 square ft shop down into a single room...the communication has never been better...and yes we do have fun with them. Thousands of steps saved and we keep finding new ways they are saving time.
