Air integrated and guages

Dear all,
I was hoping someone could tell me what happens to an air integrated
computers gas absorbtion modelling when it losses contact (albeit
unlikely and for a short period of time) with it's transponder? Does
it continue to calculate the dive as per a non-integrated computer?
Does it re-calibrate the modelling when the transpoder comes back
online? What are the safety issues associated with this?
I was also considering streamlining by ditching guages and going
entirely from the computer, although I appreciate redundancy is good,
I feel that within the limits of my normal (no deco, square profile,
<30m) dives the option to surface in the event of the computer going
down is always there, I'd appreciate any thoughts you have on this!

Cheers in advance

Sid
