How do I set "westerly" coordinates on the AHRS/ GPS system?

[Andurula]

I am on the NTTR map trying to enter coordinates into the GPS system and I can't find any explanation for how to switch the default "Easterly" coord option for a Westerly.

Any suggestions?

When entering data into the CDU, the CLR key toggles East/West at the start i.e. before entering degrees and minutes.
