Question: What does the flashing "wrench" icon in the lower left corner of the screen indicate? (lost my instruction manual)
Document: I had this computer for little over a year and put about 900 miles on it. Until recently, it worked flawlessly, was easy to install, and was accurate. Within 6 months, a black spot had appeared on the screen, due to the heat and sunlight, in the lower left corner - luckily it didn't obscure anything on the screen. A couple of weeks ago is when it started acting up. It either didn't read the sensor at all, or it would fluctuate between 19mph and 22mph.
Right now my computor is flashing the "wrench" icon and I don't know exactly what that means. Is it a reminder to service the bike or a signal that batteries are getting weak? Thanks for any help.
I haven't actually tried this out yet - just finally got it installed on my bike. The instruction manual is seriously misleading. If you just got this product, don't pay attention to the pictures and just follow the written instructions. The pictures make you think the sensor should be installed on the left side of the bike, while the instructions tell you to do it on the right.
This is the third summer using the Bell 15 function computer and it still works fine and total mileage is 1250. Mine is mounted on a Trek hybrid bike and I ride both paved and gravel roads. I have lost the instructions and remembering how to reset the readings each spring has been a bit of hassle. The main thing to know is that the screen can not be showing the scan icon or you won't be able to clear the current readings.
Just arrived for my wife's bike.Looks nice. Good quality of plastic parts and clear screen.Right button is MODE, Left - SET, but this useful info is not listed in manual  If it's your first computer device in life, it's may make trouble for next 5 minuts. But!!! Read manual FIRST!!! You'll avoid instalation problems!If it turns off, don't wait automatic start. You have to push one of the buttons before riding. I don't think it's a big problem.
The instructions are horrible! So I will tell you, the mode button is the lower right and the set button is the lower left, the top button is the backlight. Before you start, get your mind in a calm patient place because you will need it.
The instruction manual is a mess - poorly written. I found that once the handlebar temperature rose above 80 degrees F that all my readings became inaccurate to the point that it would tell me that I was standing still while I was going over ten MPH.
It took about 10 minutes with screwdrivers and broken fingernails to fix it. The installation trouble did not end there. I followed the instruction manual to the letter, only to find that some of the instructions did not make sense. The instructions say to install the sensor piece and magnet on the front right side of the bike.
I bought the Bell 200 at Walmart, came home, installed and went biking. It's a piece of crap.First of all, the instruction book goes through how to install it, and how to program it...but NO WHERE in the manual, does it even tell you how to USE it. So, you start pedaling, and stop...the thing keeps running, as if you are still going.
This bike comp is difficult to program and the instructions are a huge pain in the neck, good luck finding them online if you loose the printed sheet. A US English reader will find several functions backwards like inputting numbers from left to right. Really how hard is it to make input tire size, date/time simple? The screen is so full of tiny info checking it while riding is awful. Remembering what button does what during your ride is another adventure.
