INSTRUCTION MANUAL
1.1. GENERAL
1.2. IMPORTANT INSTRUCTIONS FOR THE DIGITAL WIRELESS SYSTEM
Your VDO series Z1 works entirely without cable; it works with double
digital wireless transmission based on well-established ANT+Sport®
wireless protocol. The ANT+Sport® wireless protocol has already
been successfully implemented by manufacturers such as Garmin,
Specialized, and Suunto. Speed signals, cadence signals (optional) to
the respective receiver (computer) as digital and coded signals. Signal
coding ensures that only the data of your own speed, and cadence
(optional) transmitters are processed (this is advantageous when riding
in a group).
The ANT+Sport digital technology is signi
fi cantly more reliable than the
technology of older analog systems. The ANT+Sport technology uses
standard industrial wireless components, and it can best be compared
to the technology used in modern WLAN networks. The connection
between transmitter and receiver is more stable, and subject to
signi
fi cantly less frequent malfunction, and it is virtually completely
safeguarded from data loss.
The speed transmitter has a memory component that buffers data eve-
ry 65 sec. Thus no data is lost if there is a malfunction lasting for this
duration.After the malfunction this data will be resent to the computer.
Subsequently the following data will be updated:
Daily distance
Ride time
Average speed
Navigator
Total distance
Total ride time
After a malfunction the data can change suddenly = updating the
computer. Initial operation of a completely digital system requires
somewhat more care than does initial operation of conventional analog
systems. The
fi rst time batteries are inserted, or after a battery change,
the transmitter automatically generates a new code. The computer has
to learn this code. To do this you must execute a DIG CONNECT SET.
Strictly follow the instructions in chapter 3.3.1. to do this.
ATTENTION: Your VDO computer is not suitable for use on motorcycles.
1.3. CONTROL SYSTEM - OPERATION
The control system of your computer is based on dual assignment of
the 4 main buttons. In this regard the devices distinguishes between
operation mode and setting mode.
