I just installed a brand new cateye cordless 7, but when the wheel spins, I initially get the
correct speed e.g. 12 mph, but within a couple of seconds it drops down to 6 mph, then jumps up
to 12 mph,

I've seen this on normal wired speedometers when the magnet on the spoke doesn't pass close enough
to the sensor on the fork. Because the magnet isn't passing quite close enough, the sensor sometimes
only detects every other pass, causing it to display half your real speed. So fist thing I'd check
is that the sensor and magnet are passing as close as you can make them.

I would also first check the sensor position - but simply as close as possible won't always be
right. Experiement with different positions (the best one may differ from what the manual indicates
going by my Cateye experience). Height is critical too. Set it in the middle of the range of
positions that work at all.

Securing the magnet firmly and using some self amalgamating rubber tape under the sensor will
help keep it all in place. If that doesn't work, *then* start suspecting battery or radio
problems, etc, etc.

Also it doesn't work very well at all in temperatures below freezing.
