Cold Computer Complications (Help!)(3 posts)

Ok I have a Shimano Flightdeck Computer. It's been working pretty good lately besides having to clean out the head unit for dust sometimes because if anything gets in there the connection stops. But its been finally getting pretty cold here in Daytona Beach Florida ( high 30's and 40's) the last few days and when i went out to go for a ride after 9 minutes my computer stopped working. I figured it was just dust so when i got home i cleaned it up a lil and it started to work at home. But when i took it out again today within 5 minutes it stopped working. But the thing is when i took it home in my nice warm house about 10 mintes later i spun the wheel and it started working again. so i took my bike out AGAIN and it literally froze up like my PC. It wouldnt change modes or anything till i got home and it got warm. Question is is this normal? Do computers do this under cold conditions? What can i do to stop it?

Thanks alot,

-Chris

I'm afraid that it is quite normal. The problem is the battery; their output decreases as temperature drops.
There are a couple of things you can try:
1. Make sure you have a fresh battery
2. Change to a lithium type battery which works much better in cold temps.
3. If it uses a wireless sensor on the wheel, try moving the sensor up the fork closer to the computer.
Hope this helps; I have the same problem to a greater degree here in Northern Maine.

Jerry's right,

I have a FlightDeck with a wireless sender. The battery in the head unit is a lithium and should last. The battery in the sender is silver or zinc oxide. Mine died about 60 days after installation. I've been riding in the 30-40F range for the last couple of months and the unit's been fine since replacing the battery.
