Verify that your display on the drill is set to the correct receiver.
To change what locator your remote looks for click the main menu icon and then on the locator icon under ‘Settings.’
Verify that both units are set to the same telemetry channel.
Under the same locator icon on the Aurora you’ll find a symbol that looks like a cell tower which represents four telemetry channels. These must be set to the same channel for the remote and the receiver.
To change channels on your receiver toggle down into the main menu and go to your ‘Settings’ option. Toggle to the telemetry icon and make sure the receiver icon matches your remote.
Check any external antenna for damage.
Ensure all internal pins are intact and clean with alcohol if connection points look dirty.
