TECHNICAL BULLETIN

TSD402/001

TSD402 CONTROL PANEL

Our Technical Support Department have received one instance regarding the facility to

record messages on the above product.

It is possible that if the microphone is pushed firmly onto the PCB, the housing can touch on

one of the PCB tracks, the resulting short thereby causing a problem which can be identified

by a background “humming” sound when recording messages.

If you have a PCB exhibiting this symptom, try gently pulling the microphone away from the

PCB, a piece of paper can act as a suitable insulator (see diagram below for location of

microphone). If this fails to cure the problem, please return the PCB to Menvier at the

address shown below.
