    Erroneous readings on wireless odometer

    Long story short, my CM4.4A wireless odometer appears to pick up signals that cause it to read wheel revolutions that do not occur. I was parked outside a store today and saw my odometer reading between 80 and 110 mph. Is this typical of wireless odometers, do I have a lemon, are there ways to minimize or eliminate this pickup? On the third question, I am sure some appropriate filtering or possibly shielding would help, but modifying consumers electronics is typically not worth the time spent.

    Anyway, curious to hear other folks experiences
    why can't I post something interesting here?

    Yes. The anti-theft stuff just inside the door does that. Worse yet, LED bicycle lights also interfere with some of them.

    check your batteries. when they get low you can get unusual readings, i know mine does.

    But some security systems operate on the same frequency and will mess with it.

    Kind of thinking it is not the battery, as it works fine most of the time, and is only 4 months old.

    I had a wired Avocet in the 90s that would sporadically measure excessive speed, ruining the average speed and distance data. Only solution I found was to replace it. I've never had another like it.

    I've had 2 or 3 generations of the Cateye Wireless, my current one is the Strada, never had a bit of trouble with these even using a Magicshine headlight mounted only inches away. When the batteries get weak on these, they simply quit working - no erroneous data / weirdness.

    The bike computer I saw that behaved funny with a light was one of the cheap ones.

    I have an LED headlight I always run on flash during the day and solid on at night, that does not upset the odometer.
