6.2 Starting the unit
Prior to connecting the unit to the PC, attach the desired
Cobra4 Sensor-Unit to it. Following the connection of the
device to the PC via the USB port, the connection is con-
firmed visually on the display of the Cobra4 Mobile-Link 2
(Fig. 29).
The upper area of the display shows the sensor that has
been identified as well as the device number (if several Co-
bra4 devices are connected via the USB interface, they are
numbered). In the upper right-hand corner, a measurement
that is started via the PC is indicated by the recording sym-
bol
.
Once the connection has been set up, Cobra4 Mobile-Link 2
and the connected Sensor-Unit are automatically displayed in
the "measure" software together with all of the measuring
channels. All further steps, such as the recording of meas-
urement values or changing of the measurement parameters,
are software-based and, therefore, not described in this
document.

CHANGING THE BATTERY
If the capacity of the battery decreases strongly, it is possible
to change the battery. Please note that damage resulting
from a battery change are not covered by the warranty. You
can send the Mobile-Link to the repairs department of
PHYWE in order to have the battery changed.
Step 1: Open the battery cover by pressing a pen or another
object onto the holder of the battery cover.
Attention
: Open the left-hand side first, followed by the right-
hand side, in order to ensure that the flat cable connector that
is located on the left of the battery is not damaged.
Step 2: Disconnect the battery connector from the circuit
board. Remove the old battery. Insert the new battery into the
holder.
Step 3: Connect the connector of the new battery.
Attention
: Ensure that the cable is located above the USB
connector or, otherwise, the cover cannot be closed.
