Testing And Verification; Restoring Factory Settings - PAC SR-TUN14H Manual

SR-TUN14H

Testing and Verification

1. Turn on the radio and check volume, balance and fade. If you do not hear any audio you may need to cycle the ignition to
initialize the factory amplifier. If there is still no audio, reset the interface according to the procedure in the next section.
2. For JBL systems, if the overall volume is too low, use the gain adjustment on the side of the RP4.2 interface to set it to the
desired level. The best way to do this is to turn the volume on the radio to 3/4 volume, then turn the gain on the RP4.2 until
some distortion is heard, then back it down a little.
3. Verify that all SWC are functioning properly. If any of the SWC are not functioning properly you may need to reset the
interface.
4. Verify AM/FM Reception, Bluetooth, USB, Apple Carplay, Android Auto and Camera(s) are functioning correctly.

Restoring Factory Settings

You can restore the RP4.2-TY11 interface to factory default settings by pressing and holding the programming button on the side
of the module until the status LED starts blinking red. Once the LED starts blinking red, release the button. You must release the
button while the LED is blinking red in order to perform the reset. Please note, the LED will go through two stages before it starts
blinking red. First it will blink green, then amber, then red.
This reset will restore the following settings to their factory defaults:
• SWC Mapping
• Factory Amplifier Settings
• Real Time Fade will be reset to on
