    PROCEDURES NECESSARY WHEN BATTERY TERMINAL IS DISCONNECTED/RECONNECTED

    Note

    After the engine switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 60 seconds (w/ Remote Touch) or 90 seconds (w/o Remote Touch) before disconnecting the cable from the negative (-) battery terminal.
