INSTRUCTION MANUAL
Power is calculated in WATT via a mathematical algorithm. Deviations
from a real WATT measurement system are possible, particularly if
there is a strong headwind or tailwind. The more precise the setting
of the bicycle used, (its weight as well as your seat position), the more
precise the displayed value will be.
IMPORTANT: If the cadence option is installed the WATT shows ZERO
when you stop moving the pedals.

8. ALTITUDE FUNCTION SETTINGS
The altitude measurement function of your VDO computer is based
on barometric pressure. The opening necessary in this regard on the
underside of the device should not be manipulated (never poke a
sharp object into this opening). Note the following for precise altitude
measurement:
a. Prior to starting each trip you must enter a start altitude into your
computer.
If you always start your trip from the same location then you only need
to enter the start altitude once.
If the start location changes then you must set the new start altitude.
b. Your VDO computer records barometric pressure changes (e.g. due
to weather changes) in sleep mode as a change in actual altitude. If for
example your bicycle is in the cellar for two days and the air pressure
changes due to weather, then your computer will show a changed
actual altitude. This is why the home altitude must be recalculated prior
to starting each trip.
c. For longer trips the actual altitude should be readjusted at certain
points (e.g. readjust to summit altitudes). Deviations can occur due to
different weather conditions at the various points of the trip. You should
make corrections so that the measurement is as accurate as possible.
Tip home altitude:
You can obtain the correct information for the altitude of your home lo-
cation or your usual trip starting point from your local weather bureau.
Tip actual altitude:
When planning trips you can
fi nd the original altitudes at certain points
of your trip on special maps. These maps are available in book stores.
