  • Loud buzzing on my Radio Intercom, IM-3003

    I have an older Nutone Radio Intercom, and the radio constantly buzzes while on .Model # IM-3003. What could be causing the problem ? I was thinking maybe the transformer needed replacement. Please advise, Thank you, Joe Fabio

    Thank you for your question on the model IM3003 radio intercom. The buzzing you are referring to is probably coming from the master itself and would need to be repaired. Please contact the Technical Service Department at 888-336-6151 for assistance.

    Thank you for your question on the model number NA300TA multi tap transformer. The NA300TA is designed to be used with the NM100 and NM200 radio intercom master stations. We do not recommend or suggest trying to use a different transformer for these units.
