Does anyone know what (if any) aural warnings the Boeing 757 Rad Alt had when it entered service in the early 1980s?

I know it later years when the Rad Alt display became alive on the ADI, at 2,500 feet on the descent, some operators had a "Radio Altimeter" aural warning but I am not sure if this was a modification that came with the later introduction of EGPWS.

Many thanks

I did not fly the B757 till mid/late 1980’s but I would suggest that Aural Warnings would be very dependable on what the customer airline required, and paid for. So in essence it was variable.

IIRC the “Radio Altimeter” callout came with the EGPWS “smart callouts”. Probably installed early 2000´s... Was not there when I first flew it in early 1990´s.
