Operation Manual

NORM PLAN MODE

TUSA strongly recommends that you review the Plan Mode dive times

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 Plan Mode 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: No Decompression Dive Times in Plan Mode are based on the

FO2 setting for Gas 1. The FO2 setting for Gas 2 is not utilized for

Plan calculations.

Plan Mode can only be accessed while viewing NORM SURF MAIN.

• Pressing and releasing the S button momentarily (< 2 sec)

while viewing the NORM Surface Main screen is displayed

will access the NORM Plan Lead-in screen.

Plan Lead-in, information includes (Fig. 40):

> Graphic FO2 with wave/clock/profile icons.

> PO2 Alarm Set Point and graphic PO2, if FO2 is set for

Nitrox, blank if set for Air.

> Tank 1 icon indicating that FO2 is for Gas (mix) 1.
