Troubleshooting
!Warning! Service Button
The black Service button on the ZN510 board allows the user to send a service pin message, which allows
efficient identification of the unit's location. However, if the Service button is held for more than 10
seconds, the ZN510 will shut down the software application and disable the unit's operation. The only
method to restore the unit is through the use of Rover service tool. We strongly suggest that this function
only be exercised under the strict direction of factory service personnel.
