FEEDBACK SENSOR INCL. TOUCH KEY
USER MANUAL
The feedback sensor incl. touch key is fitted with a maintenance-free rechargeable
lithium-ion 3.6 V/680 mAh battery.
Caution
7.3 Plugging in Bluetooth receiver for sensors
►Before switching on the THERA-Trainer software, the Bluetooth receiver for
sensors 1must be plugged into a free USB interface on the control and
display unit.
If the Bluetooth receiver is first inserted after the THERA-Trainer software has
been switched on, it will be unable to make a connection to the feedback sensor
incl. touch key.
If the Bluetooth receiver for sensors is pulled out while the THERA-Trainer
software is turned on, the connection to the THERA-Trainer software will be
interrupted and can only be restored by restarting.
7.4 Starting THERA-Trainer software
►Switch on control and display unit.
►THERA-Trainer software starts automatically.
When the feedback sensor incl. touch key is then switched on, a connection is
established. The feedback sensor incl. touch key is now ready for operation.
The user manual for the THERA-Trainer software and control and display unit
must be observed when using the feedback sensor incl. touch key.
This ensures that the feedback sensor incl. touch key connects to the right
system (control and display unit with THERA-Trainer software). Two systems
should never be started at the same time.

FEEDBACK SENSOR INCL. TOUCH KEY
USER MANUAL
Caution
Warning
The feedback sensor incl. touch key is supplied with a USB charging cable as
standard. This can be used to charge the battery from a USB interface (computer,
control and display unit, etc.) without a feedback sensor USB charger.
Do not use within 1.5 metres of the direct surrounding of the patient.
►Only use USB chargers recommended by the manufacturer.
Standard USB charger for feedback sensor:
Available from the manufacturer as an option.
- Is not a medical-device USB charger for the feedback sensor.
- Do not use within 1.5 metres of the direct surrounding of the patient.
Use a commercially-available USB charger (with CE marking).
- 5 V (d.c.)/0.5 A
- USB connection
- Do not use within 1.5 metres of the direct surrounding of the patient.
The service life of the battery depends on its charging/discharging cycles and
storage temperature.
Possible energy performance of batteries:
Approx. 1,000 partial discharges
The feedback sensor incl. touch key is fitted with over-discharge protection
for the battery.
When the battery is discharged:
When the remaining charge (based on the capacity still available) is under
30 %, the activation/charge status LED will flash green-orange.
When the remaining charge (based on the capacity still available) is under
15 %, the activation/charge status LED will flash orange.
If the battery is fully discharged, the activation/charge status LED will be off.
An operating period of approx. 10 hours per charging cycle can be obtained
depending on the conditions of use.
The battery capacity will decline over time.
The manufacturer recommends having the battery replaced by a trained dealer
after 2 to 3 years, depending on the number of charging cycles.
Faulty USB charging cable connection due to USB cable
being plugged in incorrectly!
Make sure that the USB charging cable plug is correctly
positioned in the charging socket when it is connected.
Observe position of plug.
Only use a USB charging cable approved by the
manufacturer.
Using an unsuitable USB charging cable or USB charger is a
fire hazard!
Only use a USB charging cable and USB charger for
feedback sensor approved by the manufacturer.

8.3 Establishing a connection
After the feedback sensor incl. touch key has been switched on, a wireless
connection is established between the feedback sensor incl. touch key and the
control and display unit.
In order to establish a wireless connection, a Bluetooth receiver for the sensors
must be plugged into the control and display unit. Only use the Bluetooth receiver
for sensors approved by the manufacturer (article no. A004-020).
If a different Bluetooth receiver is used, no wireless connection can be established.
The LED of the connection status indicator indicates the following status:
LED flashes green:
A connection is being established between the feedback sensor incl. touch
key and the control and display unit.
This can take several seconds.
If a connection cannot be established, the feedback sensor automatically
switches off after approx. 3 minutes.
►Check whether the feedback sensor incl. touch key is too far away from
the control and display unit.
- The wireless connection has a range of about 5 metres.
►Check whether the control and display unit is switched on.
►Check whether a Bluetooth receiver for sensors is plugged into the
control and display unit for the wireless connection.
►Check whether the correct Bluetooth receiver for sensors is plugged in
(article no. A004-020).
►Ensure the correct Bluetooth receiver for sensors is plugged in before
starting the THERA-Trainer software.
LED lights green:
A connection is being established between the feedback sensor incl. touch
key and the control and display unit.
