Polar CS200cad Cycling Computer Heart Rate Monitor with Cadence Immediately

I'm a user of the CS-400 for several years. I swap the receiver between my road bike and my mountain bike. It has two wheel diameter set-ups but fortunately both my bikes have identical circumferences. I want to try to offset any complaint that the sensor does not work well. Actually, it might require some adjustment of the location so I have a few tips. I've used the CS-400 for years and had zero problems after setup. Setup can be somewhat frustrating sometimes though. That's why I decided to enter my two cents here.

1. Mount the sender/transmitter/pickup device and the monitor on the same side of the bike. These guys don't work very well if there's material between the two. Make sure the monitor is overhanging the handlebar or it can't "see" the transmitter. I can imagine that a fat road bike bar wrapped with rubber tape might cause the unit to be hidden from direct view of the fork-mounted transmitter.
2. Locate/position/install the transmitter very close to the magnet. As close as possible without clicking as it spins past the transmitter. A light will flash one time for each time there's a signal pick up when you're testing to see if there's a pick up between the magnet and the fork-mounted transmitter. Sweet! When the wheel rotates past the transmitter, a dim red light flashes one time. This tells you that the sensor/transmitter is picking up the signal from the magnet. Spint the wheel a few times and you'll hear a beep from the monitor as it automatically turns on. You have to set the program to AutoStart for this "beep-on" feature to work. After a few flashes, the light goes to sleep so if you're still testing after a few minutes you might not get the flash so don't think it's not working. Let it rest a few minutes and start again and you'll see the dim red light flash if the magnet is properly placed.
3. I like to use zip ties to install the hardware but beware, zip ties slip unless pulled very tight with a zip-tie puller which is basicaly a plier-type tool that grabs the tail of the zip and tugs it as tight as you dare to squeeze the handles. Buy or borrow one and the zips will hold forever. Fail to pull zips super tight is a guarantee that something will move after a while.
4. I don't know what kind of cadence magnet they are currently sending in this kit but mine was a tiny flat rectangular shaped magnet with sticky tape and a band of adhesive tape to wrap around the crank arm. Not good enough. A shop gave me a better crank arm magnet which is housed in plastic with a slot for a zip tie. See if you can find one of these for a better way to fasten it to your crank arm.
