Avocet 50 cyclometer - automatic power off

I've just started riding again after four or five years. My Avocet 50 needed new batteries of course
- but when I'd fitted them and set the machine up (following the pdf manual from the avocet site),
the display stayed on permanently and the batteries wore down after 2 weeks - not surprisingly, I
suppose...

I'm sure there was an automatic power-off function last time I used it ;-) Or have I misremembered
(again)? And if so, why did the batteries run down so quickly?

Thanks

David

There is a trick you are supposed to do to get the batteries to last longer. Something about the
sequence of installing the new batteries. It is in the instruction manual. I don't have mine with
me, or I would quote the procedure for you.

Thanks - I think I've found it on the net now. I'll try it out...

I have an Avocet 50 that I've used for about 10 years. The batteries are usually good for just over
a year. Cumulative elevation gain starts to get bizarre when the batteries are just about shot.
There is no auto-off/sleep mode. Is it possible that you used the wrong or very old batteries? Tell
us what the "Trick" is when you find it. Sure didn't jump out me looking at the manual online.

Haven't got the batteries yet, Bill, so I don't know whether it's a good 'trick' or not...;-) But
when I do, I'm going to try the following (from Sheldon Brown's website (which is pretty damn
interesting all round - thanks Mr B....). :

http://www.sheldonbrown.com/cyclecom....html#avocet50

====================
Battery: two 386 silver oxide 1.5 volt.

When installing batteries in the Cyclometer 50 use this special double insert procedure: Insert both
batteries. Remove one battery and leave it out for 15 seconds. Reinsert the battery you removed. The
unit will then go into calibration mode.
====================

cheers

That will reset the 50 to defaults but I can't imagine that it will have an effect on battery life.
I have always just pulled out both batteries and stuck in the new ones at replacement time. It wakes
up stupid. Program settings and go. One interesting note. You can change between mph and kph on a
ride without loosing current ride data. Hold down both buttons long enough to get to the settings
sequence, toggle through, make changes and continue with current ride info maintained and changed to
new format. Occasionally useful for some of us kilometer confused when riding in Europe. Bill
