First
disconnect the power supply, then remove the display from the trainer
Put
the display with front side down
Take
out the 4 screws with a screw driver by turning them counter
clockwise.
Get
a good hold on the complete display to avoid it opening while turning
and turn with the front side up on your workstation.
As
the front side is facing upwards and all 4 screws are taken out you
can carefully lift the left side of the front cover.
As
soon as you can, take a look at the inside to see where the membrane
cable is located to prevent it from breaking.
See
the membrane cable shown in the picture. This cable breaks easily and
can only be replaced by replacing the complete upper cover.
Take
out the membrane flat cable by gently pulling it out in the vertical
direction. (upwards)
As
the membrane cable has been released you can fully take off the front
cover.
Once
the front cover has been removed you can easily access the CR2032
back up battery.
Take
a thin hard tool, such as a knife or a small screw driver to tilt the
battery out of its housing.
Note:
mind the polarity of the battery.
the
+ pole should be facing always upwards.
You
can see the battery type as well as the polarity sign on the battery.
The
required battery type is: CR 2032
Replace
the empty battery with a new battery by pushing it in position
gently.
Make
sure you put the membrane cable back into the socket again.
Note:
avoid contact with the connection end of the flat cable. We advise
cleaning the cable contacts with contact spray before assembling.
Press
in the connector gently and keep your hands as close to the slot as
possible to avoid the cable from bending during the assembly.
Close
the upper cover again and turn it upside down on your workstation
again.
Assemble
the display again by fastening the four screws.
Note:
After replacing the battery, all user data is lost. Computer will
show Error 162 ~166.
This can be solved by
overwriting the existing users again.
After
installing a new back up battery.
When
you have installed a new back up battery you will lose the parameter
stored in the user interface boards EPROM.
This
can be solved by the following procedure.
Enter
the engineer mode by:
<EXTRA> function
key
<OPERATION
KEY 1> top
key on the left
<UP>
<DOWN> Navigation
key
<RIGHT>
<LEFT> Navigation
key
<OPERATION
KEY 1> top
key on the left
You
can exit the engineer mode by pressing the <Training> button at
any time.
First stage of engineer
mode shows
Time
and distance value
The
lower memory shown in the display can be cleared by pressing the
lower operation key.
Press
the Right navigation key to go to the next stage.
Second stage of engineer
mode shows
Trainers
parameters stored in display EPROM.
Restore
parameters by pressing the third (bottom down) key on the left, to
update EPROM. This will be confirmed by the message “Write ok” on
the bottom line for a second.
Press
the Right navigation key to go to the next stage.
The
second stage of engineer mode also shows the measured speed and power
consumption of the brake. If you would like, you can start to pedal
in this mode. You can adjust the tension by pressing the – or + in
this mode to see the values change.
Third stage of engineer
mode shows
Error
log. Including the history and error quantity.
The

It
shows the currently stored users andtheir password. This cannot be
cleared but only monitored.
Press
the Right navigation key to go to the first stage.
Some
important error codes to mention are:
Error
code 131-138 : User data corrupt. Overwrite users to solve
-
: Low battery voltage. Replace battery to solve 161-166 : Parameters corrupt. Update EPROM to solve.
If
any other error code appears or the given solution does not solve
your problem, please contact our service department.
