Enclosure Integrity Check
Plug-In Electrocorder Physical Condition Inspection
You appear to be using plug-in Electrocorders, with integral plugs for regions or standards, UK/Ireland, Europe, Australia/New Zealand and NEMA.
The screw bosses on these cases are possibly at or near their end of life. We advise you to inspect the three screw bosses on each side of the case (six in total). It is vital that the screw will tighten and when fully assembled the 2 halves of the case cannot be separated with moderate force.
This advice concerns plug-in models: EC116, EC132, EC164, EC264, VC/32, VC/64, early EC-1V and EC-2V.
