Hi,
Every couple of months the sim card (module) on my Visonic PowerMaster 33 system stops working.
I get the "invalid sim card" error even though the system is currently setup to keep the sim alive.
Whenever this has happened in the past, I have opened the main unit and used the sim in a spare mobile phone to make a call to ensure that the sim is sill active. I have then put it all back in and it has worked fine.
Yesterday the same issue happened once again and I followed the same process as the previous times to make the call etc.
But this time I am getting the "CPU tamper alarm" and I can't seem to set my alarm as it is showing "Not Ready" on the power panel.
I opened the main unit again and checked all the connection and couldn't find any obvious issues. For a short time the system showed as "Ready" and goes back to the "Not ready" mode.
How do I clear the system troubles?
