Two guys are hidden under a wooden port. They wear wetsuits and they seem to be recording a conversation with a walkman.
Here's the walkman; it has two red stickers: one at the top (to hide the SONY logo) labeled as "DGK/32" and one at the bottom labeled as "484/GK". It's clearly a SONY WM-F5 which, BTW, doesn't have any recording feature.
A diver gets out of the sea. She is Pola Ivanova (Fiona Fullerton) and wears a SONY WM-F5.
Pola unlocks the security lock of the walkman. This model is water resistant.
Now she pulls out the tape with the recording.
She trows out the walkman and look at the tape. It has an important secret conversation of 'the bad': Max Zorin (Christofer Walken).
She and 007 get together and take a bath. After it, she quickly gets the tape and run out...
...Where a man is waiting for her and the tape. But they were shocked to realize that it has only classical music.
Because 007 has copied the secret conversation in another tape and then recorded music over it. It's clear that it's a Philips UF-I 90 cassette
So Bond (Roger Moore) was smarter than the girl and finally gets the recording.
