cateye wireless computer - transmission probs

[robjh]

I've just picked up a second-hand Cateye Cordless 7 cycle computer. The trouble is that it doesn't transmit very far, and certainly not as far as the handlebars where the display unit is.
I've replaced the batteries, so it's not that.
Performance is impeccable at 2cm, reliable to about 15cm, but completely loses the signal at any more than that, and nothing like the 70cm range in the manufacturers' blurb.

Has anyone else had this problem ?
Is there anything I should try, or do I just chuck it away and go back to wired ?

One final consideration is to optimise contact between transmitter and receiver by moving handlebar mount forward and transmitter towards the front of the fork so as to maximise line of site. This has worked for me in the past.

I found mine quite reliable until I used it with my GPS, when it would pick up a signal maybe one in a hundred revolutions. Do you have anything else in the vicinity that could be affecting it.

Also did you replace the batteries in both the handlebar and fork bits?

Never had any problems with my Cateye cordless computers.

Flat batteries in the transmitter?

Transmitters upside down?
(sorry wild guess)

This could well be why it was for sale.

thanks for all the suggestions. I tried everything but to no avail, so am going back to wired. At least there's one less thing to go wrong.
