I had an infrared connection problem with my Polar Heart rate/ Cycle Speedo and in the end it was the Infrared USB receiver i had plugged into my pc which was busted.As soon as i tried a friends Infrared receiver it worked.If that is not the case with yours then maybe the infrared receiver's drivers are not installed on your pc,stopping it working.

With your speed sensor not working,it could either be the batteries in the wheel sensor or the actual polar watch are low or flat or the wheel sensor is not close enough to the small magnet that should be attached to one of the spokes on the wheel.They should be set so that they are almost touching,about 2-4mms apart.

Hope that helps,let me know more detailed info if you still have trouble

My original RM-C1502-1C remote [gradually] stopped working. Bought a new one. This worked perfectly for 1 day then stopped working except randomly/intermittently.

Remote or infra red sensor in tv


Many times remotes just need cleaning. Take it apart an if you feel a clear liquid under the keypads, clean it off an it will work. The silicone used on remotes ages an leaves a film that stops it from working

Remote won't work but can manually operate


you do the camera tricks just to ensure if the infra red sensor of the remote is working. get a digital camera turn it on,then get the remote controller. press any button at the remote controller pointing to the digital camera, if you see a light at the display of the camera then the infra red sensor is good but if no light either the sensor is worn out or the circuit was defective.

Remote does not respond to any function, tv is on and cannot change chanel or anything, frozen


you need to check the battery contact with the battery terminal make sure that the terminal is clean.

check open the cover of your remote and check the solder of the battery terminal from the pcb board use a soldering iron resolder it.

using your cellphone camera test the infra red emmision of your remote control aim the camera to the infra red of your remote.you must see at the screen of the camera that the infra red is lit when any button is pressed..if not the infra red is busted.

using your cellphone camera again to test the infra red emmision of your TV. Aim the camera to the infra red of your TV.you must see at the screen of the camera that the infra red is illuminating.if not the infra red sensor of the TV is busted.

Cannot connect wireless keyboard and mouse


I am assuming that this is an INFRA-RED device, with
plug and play capability.

1) Make sure that the infra-red port is turned ON on your PC,
in the BIOS and in Windows (using control panel)

2) Make sure that the infrared driver is working:

My Computer ==> Right Click ==> Properties ==>
Hardware ==> Device manager ==> ....

Find the Infra-red device and check its status.

Some laptops have a mechanical switch witch controls all
wireless ports. If you shut-off the Wi-Fi, the blue-tooth and
the infra-red will also be disabled.

3) Check for tiny reset buttons on the keyboard, mouse and
the receiver. Press them repeatedly.

4) If the device is communicating, and infra-red ICON
should appear on you taskbar (RHS).

Right click the icon and make sure you enable IR
communications AND plug and play.

5) Make sure you have installed any drivers that came with
the keyboard, if any.

6) Again, make sure that infra-red communications are enabled
in the control panel.

5) Failing that, it is possible that the keyboard is defective,
or the infra-red port on your laptop is NFG, it would not
be the first time.

6) You may want to take your keyboard to a computer
shop, and ask the staff the try it with a different PC.

Alternately, try a different keyboard with the laptop.
