iPad Symptom

Troubleshooting

iPad won’t turn on

-Turn your iPad off and on. Press and hold the Sleep/Wake button for a few seconds until a red slider appears; then slide it. Press and hold the Sleep/Wake button to turn on again.

-Reset your iPad. Press the “Sleep/Wake” button and the “Home” button simultaneously for at least 10 seconds until the Apple logo appears on the screen. This reset will not damage your files.

-Battery may be drained. Plug iPad into your computer or AC adapter and see if anything happens. The iPad will recognize it has been connected to a power source and charge its battery. If it will no longer charge, the battery must be swapped with a replacement battery. Battery level displays in top right corner of iPad.

Cannot get an active baler connection

-Make sure that your Bluetooth accessory and iOS device are close to each other when connecting (for BLE modules only).

-For IIC module connections, make sure a quality power/data transfer cable is being used. Lesser quality cables will charge iPad but not allow data transfer.

-Make sure that your Bluetooth accessory is on and fully charged or connected to power. 

-IIC corded iPad connection needs minimum of 20% battery charge on device to connect.

-Restart your Bluetooth/ IIC receiver, by removing power and reconnecting after 30 seconds.

-Make sure that you are using the current Hay App Version from the Apple store. Update app if needed.

-On your iPad, go to Settings > Bluetooth and make sure that Bluetooth is on. If you can’t turn Bluetooth on or you see a spinning gear, restart your iPad

-Unpair the Bluetooth accessory, put the accessory back in discovery mode, then pair and connect it again. By tapping on its name in the Bluetooth accessories tab and then Forget this Device. In settings, tap on a device’s name, then Unpair.

-Display connector plug and bale rate sensors plug are switched on THS. Switch connections.

iPad touchscreen is slow or does not respond

-Screen may be dirty. Clean screen. Unplug everything, turn off iPad and with soft, lint-free, slightly damp cloth gently wipe screen. Do NOT use window cleaners and paper towels.

-If you have a screen protector sheet, try removing it.

iPad is not charging or is slow to charge

-In order to charge your iPad you can try either connecting your iPad to a power outlet or connecting to a USB 2.0 port on a computer. However, note that computers generally don’t supply enough power to their USB ports to be able to charge an iPad. When this happens, a “Not Charging” message will appear.

How can I unlock my iPad if I forgot the passcode

-If you cannot remember the passcode, you will need to restore your device using the computer with which you last synced. This allows you to reset your passcode and resync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present.

How do I send in my iPad for service?

-Refer to your iPad owner’s manual or contact Apple.

DO NOT SEND iPad TO HARVEST TEC.

For other issues refer to your iPad Owner’s Manual or contact Apple Directly
