Connecting Your Smartphone
to the Vivera Stretcher Trolley
Conditions for Connection
The following points must be observed to connect to the stretcher trolley:
• Turn on Bluetooth on your device.
• Break the Bluetooth connection with other devices.
• Shut down all applications running in the background.
• Keep your device close to the stretcher trolley.
For the application to work properly, never pair the stretcher trolley using the
Bluetooth settings on your device.
Connecting to the Stretcher Trolley
1. Activate the stretcher trolley (display panel lights up – battery status indicators).
2. Launch the “Vivera Nosítka” app (Fig. 1).
3. After loading the application, the initial screen is displayed (Fig. 2).
4. The application will automatically start searching for stretcher trolleys in the
vicinity. All found stretcher trolleys will be displayed in sequence on the page, e.g.
VIVERA20001 (Fig. 3).
5. Select the stretcher trolley you want to connect to from the list.

Displays the number of seconds to automatic sleep. After pressing any button on the
stretcher trolley, the value is reset.
The timer value can be set on the “Basic Settings” screen under “Sleeping time” (p. 17).
Data download button
Downloads the data from the control unit. These data are needed for more accurate
diagnostics and displaying the graphs; see chapter “Graphs” (p. 25).
The download procedure:
1) Select the download range:
a) From date – downloads all data from the selected calendar day.
b) From last download – downloads all data from the last download till now.
c) Last 1000 records – downloads the last 1000 records.
2) Press the Download button.
3) After downloading, select how to save or send the data.

Adjusting the Stretcher Positions
Adjusting the three basic height positions is essential for the correct and safe operation
of the stretcher trolley.
After adjustment, always check that all positions are set correctly. Do this without and
with a load.
The height positioning is described in more detail in the manual of the stretcher trolley
or monoblock.
Adjusting the lowest position
Adjustment procedure:
1) Lower the stretcher as low as possible.
2) Press the corresponding button on the home screen to adjust the lowest position.
NOTE
If the stretcher trolley does not brake properly when moving downwards, set the lowest
position approximately 2–3 cm higher than the mechanical lowest position.
Adjusting the ambulance position
Adjustment procedure:
1) Move the stretcher to the required height for comfortable loading into the
ambulance (2–3 cm above the slider that is part of the loading system).
2) Press the corresponding button on the home screen to adjust the ambulance
position.
Adjusting the highest position
Adjustment procedure:
1) Raise the stretcher to the desired height. If the height range is unsatisfactory, use
the Service mode function to increase the range.
2) Press the corresponding button on the home screen to adjust the highest position.
Service mode button
Adjustment procedure:
1) Activate the service mode (button is green) and carefully move the stretcher to the
desired height. Pay attention to the mechanical capabilities of the stretcher trolley.
2) Deactivate the Service mode (button is grey) and follow step 2 in “Adjusting the
highest position”.

Graphical position indicator
The coloured markers on the right side show the set height positions.
Blue marker – the lowest set position
Red marker – the ambulance set position
Green marker – the highest set position
The indicator on the left side shows the current stretcher position and the exact value
in units of angular points.

The lowest set position

16
Relative cycle counter
The relative cycle is related to the difference between
the set values for the highest and lowest positions (see
“Adjusting the stretcher positions” on p. 14). One cycle
is added when the difference between the highest and
lowest position is reached. The value of this difference
therefore varies according to the current settings of the
limit positions.
The values for recording a cycle are added regardless of
whether the direction of movement changes.
Basic Settings
The application allows you to change the settings of some system functions. Always fill
in all the values of the adjustable functions before pressing the Send button.

17
Setting the norms
The norm determines the value of the angular points
(see chapter “Graphical position indicator” on p. 15). To
record one cycle, the norm value must be reached by
continuous or step-by-step movement in one direction.
If the direction of movement changes before the norm
is reached, the calculation is interrupted and the cycle is
not counted.
Current date and time
Display of the current date and time.
Adjustable system functions
Sleeping time
Setting the countdown time to sleep; see chapter “Home
screen” on p. 12.
Releasing time
Setting the time for the reverse movement to release the
pressure in the system.
Weight limit
Setting the limit of angular velocity at which the motor
braking will be activated when lowering the stretcher.
Set a lower value for braking at lower loads and vice
versa.
Charge limit
Setting the voltage value [mV] at which charging in the
loading device (12V circuit) is initiated.
Pull after 12V unplug
Function for automatic retraction of the undercarriage
after disconnection from the charging connectors in the
loading device (12V circuit).
Auto pull up
Function for automatic retraction of the undercarriage
when the monoblock/chassis rests on the sliding arm of
the loading device.
Motor direction
Setting the direction of motor rotation.
