I have a fault with my cambridge version 2 which I
wonder if any one else has experienced. I will try
the agent but in between time .....?
On a recent flight the speed to fly indicator played
up showing full pull up advice with settings Mc 0
speed 45 knots and showing 2 down ! Before this it
has been good for the two years I have had it
It is 15 years old so maybe it has had its day ? [
like me ]

Any ideas folks

Check your plumbing for pinches or leaks.
Input errors lead to output errors.
Good luck

Also---check the battery--a little coin-cell battery. When dead, you lose
your polar setting, and a lot else.
Small leaks in plumbing--esp to the flask--lead to wierd readings.

Agree with battery - if you can not get the original battery 2032 fits the
holder OK - also look for cracks it the original red silicon tube used
internal within the unit - I had one woth a lengthwise crack in tube which
only played up in the air

Ditto on the battery. Had the exact same symptoms you described last
year. Replacing the backup battery immediately fixed it. Of
course, you'll then have to re-enter the polar and other settings, but
it should be good as new after that.
