2 Safety Information
Danger
• Explosion Hazard •
The device is not designed for use in areas where an explosion
hazard may occur.
Explosion hazards may result from the use of ammable anes-
thetics, skin cleansing agents, or disinfectants.
Warning
• Patient Hazard, Equipment Damage •
Do not expose the xr50+ to direct sunlight to prevent system
components from reaching inadmissible high temperatures.
Do NOT use the xr50+ outdoors (medical device). Furthermore
the device has no additional protection against the ingress
of humidity. Humidity inside the device may cause equipment
malfunctions and increases the risk of an electric shock.
Additionally, the device should not be operated in the vicinity of
power systems, because they may impair equipment functions.
The xr50+ may only be used in combination with accessories
approved by ergoline GmbH.
• Risk to Persons •
Before using the ergometer, the operator must ascertain that it
is in correct working order and operating condition. The cables
and connectors, in particular, must be checked for signs of
damage. Damaged parts must be replaced immediately.
• Equipment Malfunction •
Only the special shielded cables supplied by ergoline may be
used to connect the device to other pieces of equipment.
• Equipment Malfunction •
Cellular telephones may not be used in the immediate vicinity
of the ergometer, because they might interfere with the proper
functioning of the ergometer.
Electromagnetic interference most probably exists when
the watt reading is unstable. If the displayed value changes
frequently even though the speed is above 30 RPM, this may
bedue to electromagnetic interference.
Warning
• Shock Hazard •
When the device is connected to other equipment or if a medi-
cal system is created, it must be ensured that the added leakage
currents do not present a hazard. In case of questions, please
contact your ergoline dealer or the ergoline GmbH Service
Department.
For use, the ergometer must always be connected to electric
installations that fulll the local requirements.
• Patient Hazard •
The German Medical Device Operator Ordinance (MPBetreibV, §5)
demands that users
• must be trained in the use of the ergometer
• must be familiar with the routines for handling and assem-
bly of the device
• must be familiar with and observe the safety rules and
regulations for operation of this type of equipment
• must be informed about any other pertinent rules and
regulations (e.g., safety instructions)
• must be informed about the potential hazards arising from
the use of this type of equipment
• make sure that no unauthorized changes are carried out.
Note
Only the removal of the power cord will result in an all-pole
disconnection of the device from the power line.
Caution
Additional equipment connected to medical electrical equip-
ment must comply with the respective IEC or ISO standards
(e.g., IEC 60950 for data processing equipment).
Furthermore all congurations shall comply with the require-
ments for medical electrical systems (see IEC 60601-1-1 or
clause 16 of the 3rd Ed. of IEC 60601-1, respectively).
Anybody connecting additional equipment to medical electrical
equipment congures a medical system and is therefore respon-
sible for the system's compliance with the requirements for
medical electrical systems. Attention is drawn to the fact that
local laws take priority over the above mentioned requirements.
If in doubt, please consult your local dealer or ergoline GmbH.

4 Preparing the Patient
4.1 Adjusting Saddle and Handlebar
The saddle height of the xr50+ is adjusted manually with a
clamping lever.
When the pedal is in its lower position, there should be a
10° angle between the axis formed by the upper body and
the thigh.
Set the handlebar to a position where it is comfortable to
reach while sitting upright.
For this adjustment, open the clamping lever
1
and adjust
the appropriate angle.
Figure 4 – 1: Adjusting saddle and handlebar
1
Adjusting the handlebar angle
2
Adjusting the height of the saddle
Open the clamping lever

by turning it counter‑clock‑
wise. Then you are able to adjust the saddle height. Adjust
the appropriate saddle height. Fix the saddle height by
turning the clamping lever clockwise until a resistance is felt.
Then tighten the clamping lever by turning it a quarter
revolution (approx.15 Nm) clockwise.
Note
• Tighten the clamping levers only as tight as necessary,
NOTwith maximum force.
• Lubricate the threads of the clamping levers every three
months at minimum with a suitable lubricant (e.g., OKS470).

5.3 Transport
For short distances, the xr50+ can be lifted at the saddle
and rolled away on its castors.
To cover greater distances with the xr50+, however, we
recommend the following method:
• Disconnect the power cord from the wall outlet.
• Rotate the handlebar of the xr50+ towards the front
and tighten the clamping lever.
• Stand in front of the xr50+, grasp the handlebar and tilt
the ergometer towards you until it is standing on the
castors only and is balanced.
• It is now possible to transport the xr50+.
• When you have reached the new location, lower the
xr50+ very carefully to protect it from considerable
damage.
Caution
• Equipment Damage •
Avoid strong vibrations of the xr50+ during transport.
Figure 5 – 3: Transporting the xr50+
5.4 Setup
Place the xr50+ on a level oor.
The xr50+ must be set up in a secure and stable position;
the two leveling feet at the back make for easy adjustment
to uneven oors. Extend the foot concerned until the xr50+
no longer wobbles.
In case of delicate ooring, it is recommended to place
a mat under the ergometer to protect the ooring from
damage by the feet.
The xr50+ has 2 castors at the front for transport.

The ergometer runs an automatic exercise test – some of
the corresponding test protocols are user‑congurable and
stored in the system.
(see chapter8.2 Exercise Test Protocols on page26)
Manual
The ergometer is controlled manually, i.e., the user performs
all load changes via the keypad.
Settings
Used to congure the ergometer.
6.3 Speed Readout
A speed readout as well as five LEDs at the top of the
control terminal inform the patient of the speed: too slow,
too fast or correct.
The limit values for the respective speed ratings depend on
the selected load (see “Note” on page21).
Figure 6 – 5: Speed readout
1
speed low (= patient should pedal faster)
2
correct speed
3
speed high (= patient should pedal slower)
Note
• If, during an exercise test, the speed drops below 30RPM,
the load readout starts blinking on the display.

The stored test protocols available for selection will be
displayed. There are ve xed protocols (protocols 1 to 5)
(seechapter8.2 Exercise Test Protocols on page26),
whereas protocols 6 to 15 are user‑programmable.
The protocol menu provides an overview of the test phases.
Example: 50 W / 2 min / 25 W
indicates: Basic load of 50 W
Stage time of 2 min
Load stage of 25 W
Use the softkeys on the right and left (↑ ↓) to position the
bar cursor on one of the protocols and conrm the selec‑
tion with Select.
Figure 6 – 10: Selecting an exercise test protocol
The exercise test is started with the Start key.
When the basic load appears on the display (after approx.
15 seconds) and the patient's RPM indicator blinks, the
patient should start pedalling.
Figure 6 – 11: Starting the exercise test
The internal protocol will now control the entire exercise
test – the display always indicates the current values.
With the +10 W and ‑10 W keys, the current load can be
changed any time (in increments of +/–1W, +/–5W,
+/–10W or +/–25W, as congured).

6.6 Terminating an Exercise Test
The exercise phase can be terminated manually at any time
with the Recovery key.
The load will immediately be reduced to 25 watts, but a
higher or lower value can be selected manually.
It is recommended that the patient continue to pedal in the
recovery phase.
The End key in the middle will terminate the test. Figure 6 – 13: Recovery phase
