P164 full reset to factory settings

[luis]

I have a P164 that was changed by the owner of the radio without knowing what he was doing, now it doesn't respond and I can't make it do the factory reset to program.
The name of the ps station and network and others cannot be changed even with the reset button on the equipment and I have already tried to restore the backup with the initial settings but everything remains the same, I installed the firmware from the website V. 2.2d., but I continue with the data without being able to change it already removed the battery 24h even so the settings remain unchanged, is there anything to reset the factory settings?

The simplest way is connecting the unit via USB cable, then make all setup necessary (see the pdf section 4.4) or upload the Restore file. There's no kind of lock or access restriction which can (after previous successful configuration) prevent further setup via the local USB port.

Please look into the manual.

The 'Ethernet defaults' button does not reset RDS content.
The battery which is installed on the board, is for internal real time backup. Its removing does not reset anything but internal clock.
Rewriting the firmware does not reset the RDS content.
