Page 11: 2. 2. Compass Mode
IST PROLINE [ Display after a dive - GAGE] --- NOTE --- Even when there is no PGT (=pressure gas in tissue) level indicated, a change in altitude will cause PGT graph to be displayed and desaturation time counted. When the PGT graph is high (on 7 or 8 levels), a change in altitude may cause the maximum nine-level graph to appear.
