NOTE: GEO. The Serial Number and Firmware Revision will be Enter them in the Records section provided in the back of requested in the event that you contact Oceanic regarding the this Manual. NORM PLAN MODE Oceanic strongly recommends that you review the PDPS (Pre Dive Planning Sequence) prior to every NORM dive to help you Plan your dive as required to avoid exceeding no decompression or oxygen exposure limits. This is especially important for repetitive dives when the PDPS indicates adjusted dive times that are available for the next dive, based on residual nitrogen or oxygen accumulation (whichever is in control) following the last dive and surface interval. NOTE: Calculated No Decompression Dive Times in PLAN MODE are based on the FO2 setting selected. Pressing and releasing the A button momentarily (< 2 seconds) 1 time while the NORM SURF MAIN screen is displayed will access the PLAN MODE LEAD-IN screen. NORM SURF > PLAN LEAD-IN 59 While the PLAN LEAD-IN screen is displayed, pressing and releasing the S button momentarily and repeatedly (< 2 seconds each time) will increase the Planned Depth in increments of 10 FT (3 M), displaying the information one Depth screen at a time. Information provided includes Depths and allowable No Decompression Dive Times. The PDPS will step through Depths from 30 to 190 FT (9 to 57 M), or to the Maximum Depth that will allow theoretical No Decompression Dive Time of at least 1 minute based upon the previous dive profiles in a series of repetitive dives and taking into account descent and ascent rates of 60 FPM (18 MPM). NOTE: When the Conservative Factor is set ON, No Decom- pression Dive times are reduced to the values of the next 3000 foot (915 meter) higher Altitude. Prior to the first dive of a series, pressing and releasing the A button momentarily (< 2 seconds) will advance to LOG MODE. PLAN Lead-In > LOG After a dive is made, it will advance to FLY MODE. PLAN Lead-In > FLY Depressing and holding the M button for 2 seconds or if no button is pressed during a 2 minute period operation will revert to the NORM SURF MAIN screen. 60 PLAN MODE LEAD-IN, information includes (Fig. 54): > Graphic PLAN > FO2 Set Point with FO2 icon > PO2 Alarm Set Point (x. xx ATA) with Nx and PO2 icons, when numerical values are displayed. Press and release the S button momentarily (< 2 seconds) to access the first screen (30 FT/9 M) of the PDPS. Fig. 55): > > Plan Depth value with F (= feet) or M (= meters) graphic. Max Depth allowed for the PO2 Alarm value set with MAX and FT (or M) icons, if FO2 is set for Nitrox. > Dive Time allowed (hr:min) for the FO2 value set with TIME and NDC (or O2 if Oxygen controlled) icons. > PO2 Alarm Set Point (x. xx ATA) with Nx and PO2 icons, if FO2 is set for Nitrox. Press and release the S button momentarily and repeatedly (< 2 seconds each time) to step through the Planned Depths in increments of 10 FT (3 M), displaying the information one screen at a time. Depress and hold the M button for 2 seconds to exit the PDPS and revert to the NORM SURF MAIN screen. Fig. [. . . ] All adjustments for Altitudes greater than 11, 000 feet (3, 355 meters) are then made to allowable dive times for 14, 000 feet (4, 270 meters). If the Conservative Factor is set ON while at Sea Level, calculations are based upon an Altitude of 3, 000 feet. The GEO will not function as a Dive Computer above 14, 000 feet (4, 270 meters).
