SERIAL NUMBER

• A and S (simultaneously for 8 sec) while viewing the NORM

Surface Main will access the SN screen (Fig. 57).

> Graphic SN (Serial Number).

> Factory programmed Serial Number.

> Firmware (operating software) revision (e.g., graphic r1A).

• A and S (simultaneously for 2 sec) will revert to the Surface

Main.

• M (2 sec), or if no button is pressed within 2 minutes,

operation will revert to the Surface Main.

The Serial Number and Firmware Revision will be requested in the event that you contact

TUSA regarding the ZEN AIR. Enter them in the Records section provided in the back of

this Manual.

NORM PLAN MODE

TUSA strongly recommends that you review the Plan Mode 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 repeti-

tive dives when the Plan Mode indicates adjusted dive times that are available for the next

dive, based on residual nitrogen or oxygen accumulation (whichever is in control) follow-

ing the last dive and surface interval.
