2.3 Potential equalisation
A standard potential equalisation stud is located on the rear panel, next to the power connection unit. It
is marked with a green/yellow information sign. Using an earth cable, the ergometer can be connected
with the potential equalisation of the examining room, which serves as a common earth point for all other
mains-operated devices in the room to ensure that all devices have the same earth potential.

2.6 Safety notes
Safety precautions when operating with other devices
Portable communication devices, HF radios and devices labelled with the symbol (non-ionic electromagnetic radiation) can affect the operation of this device (see section 2.7).
2.7 Eliminating electromagnetic interferences
1. The unit is only designed for operation in the following electromagnetic environment: Radio frequency emission according to CISPR 11, group 1, class B.
2. Group 1 means that the ergometer exclusively uses HF energy for its internal function. The HF emission is therefore very low and unlikely to disturb electronic devices in the vicinity.
3. Class B means that the ergometer is suitable for use in any facilities including residential areas, even
if it is directly connected to the public mains that also supplies residential buildings.
4. The general electromagnetic environment with regard to the device's electromagnetic immunity is
defined as follows: the voltage corresponds to the typical business or hospital environment, and the
humidity is at least 30%, especially if the floors are synthetic.
5. If disorders should nevertheless occur, especially in the vicinity of devices labelled with the symbol
"non-ionic electromagnetic radiation", check the recommended minimal distance according to the following table. More information is given in the service manual.
Recommended safety distances between portable and mobile HF telecommunication device s and
the ergometer
The ergometer is designed for operation in an electromagnetic environment with controlled HF disturbance.
The user can help avoid electromagnetic interferences by keeping the minimum distance between portable
and mobile HF telecommunication devices (senders) and the ergometer, depending on the output performance of the communication device a s ind icated below.

3 Installation
3.1 Location
Install the device in a suitable position (refer to safety instructions in section 5).
The unit should not be stored or operated in wet, moist or dusty surroundings. Nor should the unit be
exposed to direct sunlight or other sources of warmth.
The unit should not come into contact with acidic vapours or fluids.
The unit should not be placed near X-ray units, large transformers or electrical motors. There must be a
distance of at least one meter between the unit and the mains network.
3.2 Assembly instructions
3.2.1 Unpacking and assembling
Install the control panel after unpacking the unit. In order to do so, insert the two tabs on the back of the
control panel into the handle bar pipe and press them downward to their stop. The operator's side should
usually face the front so that the display can be seen by the person operating the machine. Connect the
potential equalisation cable to the flat plug at the back of the control panel.
Connect the main plug with the connecting socket. Fasten the rear cover with 4 screws.
Remove the seat's transport protection.
With the help of the base adjustor on the rear lower side of the ergometer, adjust the device so that it is
flush with the floor. The ergometer is then fully stabilised.
3.2.2 Seat adjustment
Mechanical seat adjustment
The seat is infinitely variable horizontally in order to accurately adjust the distance to the pedals. The
seat can be adjusted for persons between 150 cm and 210 cm in height. The handle next to the control
console ensures safe grip while positioning the feet on the pedals.
A ball-grip lever is used to adjust the sitting position. This lever is located on the right hand side, underneath the seat, and is easily accessible. Press the ball handle downwards to unlock the seat break, and
adjust the seat until the correct sitting position has been found. Pull the lever upwards as far as it will go
to lock the seat.
The seat construction is designed for patients weighing up to 250 kg.
Motorised seat adjustment
Adjust the seat by use of the arrow buttons.
3.2.3 Connecting the blood pressure cuff
The interfaces for the air tube and the microphone are located underneath the seat's guiding rail. Connect the blood pressure cuff by screwing the hose connection onto the joining nipple and inserting the
microphone plug in the socket next to it.
3.2.4 Mains connection
Establish potential equalisation (see section 2.3) and plug the supplied power cable into an earthed
socket. As the device is preset to the local mains voltage (refer to section 8.4), you can switch it on using
the main switch at the front.
