Need help for Polar S510 or S710 set up?Frankl

I am trying to set up my S710. but the reciever seems to have problem picking up the sigal from the speed and the cadence sensor? I have the correct distance (i.e. the speed and the cadence sensors are not TOO far away from the reciever).

I am wondering how's everybody's system working out for you?
Is there any pix?

I have a S710. It works ok (there are things I'd like to change but they are minor). However, I've found the units to be incredibly sensitive to electronic interference and distance. Mine will pick up the speed if the watch is on the handlebar holder and the speed sensor on the front fork, but if I wear the watch or try the speed sensor on the rear wheel it won't pick up.

The cadence seems to have a slightly stronger transmitter, but not much. On my wife's bike the cadence signal can be picked up if the transmitter is on the down tube, but not if the transmitter is on the seat tube.

Neither cadence nor speed can be picked up if I mount my GPS on the handlebars - interference from the GPS blocks the signals from the transmitters and the S710 won't pick them up.

It can be confusing to get the 710 to display speed and cadence if you don't follow the instructions in the booklet exactly. Let me know if that might be the problem and I can suggest some shortcuts.

First - are you getting HR information? This would inidcate that the watch is OK. Next, if you're around a high voltage source the EMF will interfere with transmission. This could be around high voltage power lines or even smaller sources inside your house, like a furnace motor. Try mounting your HRM on your handle bars so that you have a normal and constant range.

Are you getting the blinking red light on the speed sensor when you rotate the tire after it has not been moving for a while? This would indicate if your sensor is picking up the pulse from the wheel magnet. The next thing to check would be to hold the watch closely and see if it picks up the transmission. If it seems to be affected by range you may want to replace the battery located in the speed sensor. Yes, the unit is new, but you can still have a dead battery. After that you might want to verify the watch battery, but you void the warranty if you open the watch - it is supposed to be done by Polar. So rather than messing with it I'd either go to the place where you bought it or call Polar.

I had problems with mine S710 until I figured how to mount it.
I mounted the speed pickup on a left side of my fork, as high as possible, right at the brake. The watch attachement is on the right side of the handle bars. This combination works for me.
If the watch is on the same side as the speed pickup, I get miserable readings. I got better readings with the watch on the stem, but then the watch is sideways and it is hard to read. Also, any time a car passed me, the watch would stop reading speed. Figure.
FYI, I have a Steelman CC bike, with a wider fork. If you are interested, I can send you pictures of what I did.

A quick question for you guys--I'm building up a new bike and looking into getting the S710. I've heard some conflicting reports from other people about the live sample rate of the watch on the speed/time measurements. I know that when you download to an external computer you only see data points in 5 second intervals or higher, but when you're actually riding, does the watch display speed in real time, or does it also only sample every 5 seconds or more?

The reason I ask this is because if it doesn't sample real time I might throw a cheap cateye computer on the bike as well just so I can see my speed while I'm actually in the saddle. Thanks!
Speed appears to be in real time.Howard2

Speed appears to be in real time. Cadence appears to have a second or two lag.

I had problems initially with intermittant pickup from the front fork speed sensor on my 710. I solved these by tilting the handelbar mount slightly forward (Front end down from level). The problem disappeared.

How does the Cadence sensor Look?

I have one but haven't installed it yet as It appears "Clunky".

Cadence senosr does look clunky when mounted (nm)Howard2
