Home Screen

The In/Out Home screen has four options:

• Line Call: Get automatic line calls
• Rec only: Record your play (no line calls)
• Videos: Playback previously recorded sessions
• Settings: Adjust device settings

Line Call

Line Call automatically calls balls in or out.

To set up:

• Click on Line Call
• Adjust the angle of the In/Out device so that both sides of the court are in view. Make sure there are no people or balls in the way. Try to ensure that the space behind the tennis courts are similar on the top and bottom screens.
• Click on Find Court. The device will attempt to detect the court lines. If it succeeds, the message "Validate" will appear. Press "Validate" and confirm that the court lines, colored in green if detected, in red if not, are properly recognized. Click again to get the overlay menu and click on the arrow "Line Call" to proceed.

In/Out will now call balls depending on its settings.

While in Line Call mode, the screen will show the last ten shots. You can use the left and right arrows to select a particular ball and click on the screen to see a replay of where the ball landed.

If the device is configure for match, all the shots of the last point are shown on screen. The serve is recognized as deuce or ad side with the green serve overlay. The speed of the serve is provided in the bottom right corner.

Rec only records your play with both cameras. Press Stop when you are done. To view the videos you have recorded, click on Videos from the Home screen.

If you have a microSD card inserted, In/Out will prioitize it over the internal 4GB memory.

Videos

The Videos screen allows you to playback previously recorded videos.

If you plug a microHDMI cable into the right side of the Net Device, you can replay the videos in high quality on a TV.

Settings

The settings section gives access to a lot of settings to tweak your In/Out experience.

• "Pair Second" allows you to pair a second In/Out device for a more accurate experience (recommended for doubles).
• "Signal" allows you to change how In/Out responds (with lights, beeps) to in and out calls.
• In/Out mode
  • Practice single
  • training single
  • Match single
  • Practice double (2 devices highly recommended)
  • Match double (2 devices highly recommended)

Pair Second

If you have a second In/Out, you can pair them together. You only need to do this procedure once. Each device will remember its pair and will reconnect to it automatically when line call is started.

Go to the "Pair Second" screen from the Settings screen on both devices. Once you see the other device, press on its name. The paired device is then highlighted in yellow. Exit the menu and go back to the home screen. The devices will be paired automatically and the status icon will be updated accordingly.

To unpair, go to the "Pair Second" screen on each device NOT AT THE SAME TIME. Press the "Unpair" button and confirm.

Signal

The setting allows you to adjust how the In/Out device responds to in and out balls.

Press the left and right arrows to switch between the six settings, and use "Test IN" and "Test OUT" to see how the device will respond when the ball is in or out.

• Light - green (in), red (out)
• Sound - one beep (in), five beeps (out)

These are six settings:

• Never - no light, no sound
• Light - light, no sound
• Sound - no light, sound
• Out Only - light (for out balls only), sound (for out balls only)
• Full - light, sound
• Custom - custom settings

Custom settings enable you to select exactly how the device should signal when a call is made. There is a close call option so that call IN are made only when the ball is very close to the line.

Training

You can place the device in training mode. The device tells you the percentage of success to the targeted zone, as well as your ITR (Instant Tennis Rating) based on that session. If you are in line calling pratice mode, press on the lower left corner to swap to training:

After making a long press in the settings screen, you can select one of the 12 training zones including serves:

In training mode, if beep is enabled, the device makes one beep when the ball hits the targeted zone, it makes no beep if the ball is IN but NOT in the targeted zone, it makes 5 beeps when the ball is OUT.

Once you have synchronized the device with the cloud, you can access your training result and ITR. Visit the cloud section for more information.

• "Line Call" toggles between "Line Call" and "Line Call + Rec".
