17 PROBLEM SOLVING:
SENSOR DOES NOT DETECT SERVE
If your Sensor is paired (the little tennis racquet in the top right lights up
green), but has difficulties recognizing serves in ‘PRACTICE SERVE’ mode
,
you have to be aware of a couple of points and take a few steps to try and solve
the problem.
First, note that the Sensor was designed only to recognize the following types of
serves: flat, slice/reverse slice/kick/topspin/American twist/reverse kick. If you
make an underhand serve or pat-a-cake serve, the sensor cannot recognize it.
In order to prevent problems in recognizing serves, it is recommended that you
hold your racquet steady before serving and wait approximately three seconds
between serves.
For problems in recognizing serves in ‘PRACTICE SERVE’ mode, please follow
these steps:
1. Disconnect the Sensor
and reconnect it.
To do this, click on the small racquet
symbol and then click on the name of
your Sensor to display the Sensor list.
Press on your Sensor, choose ‘Forget
Sensor’ and confirm your selection
(see Point 14). Then reestablish the
connection (see Point 8).
2. Completely charge the Sensor
Depending on which type of power
source you use, the complete
charging cycle takes around 1.5–2
hours. When the LED display on the
charging device is continually green,
the Sensor is fully charged.
3. Restart your iOS/Android device
To do this, hold down the on/off
button for four seconds and slide or
press the ‘turn off’ button.
4. Turn off Bluetooth on all other
iOS or Android devices
Turn off Bluetooth on all iOS or
Android devices in the vicinity, then
deactivate the Bluetooth connection
on your mobile device and activate it
again (see Point 8).
5. Delete the app and reinstall it
