What to do, if ...?

In the case of a failure ................... what to do if...?
All devices undergo a detailed test before they are shipped.
Should you, in spite of this, face a functional failure, the following recommendations should tell you what to do.
General procedure to identify the cause of a failure
III
The device consists essentially of two functional units
- the dashboard and the drive unit.
The drive unit is located inside the device, behind the saddle column. It contains the power supply, the eddy current
brake and the related electronic circuits.
The dashboard contains the electronic circuits used for system control, display and data processing. The dashboard
and the drive unit communicate via a cable, which is routed through the handlebars column, having a connector on
the dashboard, on the drive unit and in the handlebars column.
Should the assembled device fail to function, the defect would generally be found either on the dashboard, the drive
unit or the cable connecting them.
The most frequent cause of complaint turns out to be jamming the connecting cable during the assembly
process of the device, or not properly plugging the cable connector.
In the event of a failure, check carefully first if
The cable connector located on the lower end of the handlebars column is properly connected, and that the cable was
not jammed or cut when the handlebars column was mounted onto the frame. To do this you need to disassemble the
handlebars column.
The cable was not jammed or cut while mounting the dashboard on the handlebars column, or if the cable connector
to the circuit board inside the dashboard is loose. To do this you need to disassemble the dashboard.
Fastening screws
All the fastening screws must be tightened from time to time. We recommend tightening them at least after the first 50 km
and then once every 500 km.
Contacting your dealer or the service department of the device
If the cause of the failure could not be identified, you should contact your dealer or the repair hotline of
daum electronic gmbh (telephone number ++49 / (0) 911 / 97 536-0).
We need the following information:
1. The device serial number
2. The dashboard version number
"Serial Number" on the graphic display).
3. The proof of purchase and the device reference sheet
4.
The devices have a built-in failure diagnostic system, which signals device functionality using a red and a yellow LED.
These LEDs are located behind the transparent side cover (to the right side looking in the front direction) in the upper
right section on the circuit board of the drive unit, and can be seen from the outside (through the grid). With the device
switched on, the yellow LED should blink when pedalling slowly, and blink faster when pedalling fast.
With the device switched on, the red LED should light with high intensity when pedalling against a low load, and
decrease in intensity as the load increases.
Please inform us of the status of these LEDs for all complaints concerning "the device is not braking" or "the device is not
braking properly." This enables us to draw relatively concrete conclusions about the cause of the failure.
