Having suffered the failure of two keypad 'speaker' modules, I am very aware of the very sensible advice given that I keep the volume at a lower level to possibly avoid yet another failure in the future. After fitting the third module, I lowered the sound level to 40 and have been very happy with the quieter voice. However, I notice that for certain functions, the voice level clearly reverts to its default value of 50. For example, I had a message waiting today and after listening to it (at the lower volume level), I pressed # to exit the system. I then got a - booming! - 'security off'. It is much more noticeable now that most of the sound is at the lower lever - when it changes, it almost sounds like the lady is shouting!!
My main concern is that IF it was a 'default too high volume' that caused the early failure of the two previous speakers, isn't this adding to the 'stress'? Is there any way that I can set ALL communications to the level I set, whatever that might be? And- if not, why not?
