The ZEN features 3 Dive Computer (DC) Operating Modes,

NORM (Fig. 2A) which is used for Air and Nitrox dives, GAUG

(Fig. 2B) used for dives in which Nitrogen-Oxygen calculations

are not performed, and FREE (Fig. 2C) used for activities that do

not use SCUBA.

Entering Settings and Plan Mode are only available in NORM

SURF Mode which also allows access to Fly, Desat, Log, and

History Modes.

GAUG Mode only allows access to Fly, Log, and History Modes.

FREE Mode only allows access to speciﬁc Free Modes.

AUDIBLE ALARM

Most warning situations that activate the Audible Alarm while

operating in NORM or GAUG Mode cause the ZEN to emit 1

beep per second for 10 seconds, or until the situation is cor-

rected, or it is acknowledged by momentarily pressing and

releasing the S button (less than 2 seconds).

After being acknowledged and the situation corrected, the

Alarm will sound again upon reentry into the warning situation,

or entry into another type of warning situation.
