The surface interval must be at least 5 minutes for a dive to be consid-

ered a repetitive dive. Otherwise, it is considered a continuation of the

same dive. The dive number will not change and the dive time will con-

tinue, where it left off (see also section 3.6.2. Dive Numbering).

3.1.4. User Definable Functions and Alarms

This Vytec has several User Definable Functions and depth and time

related alarms that you can set according to your personal preference.
The dive computer model, unit of measurement and backlight prefer-

ences can be set in the MODE- SET- SET PREF submode. The dive

time and the depth alarms can be set in the MODE- SET- SET DIVE

submode and the alarm clock can be set in the MODE- SET- SET TIME

submode. Setting of the user definable functions and alarms are ex-

plained in detail in section 4.3. Set Modes.

3.2. SAFETY STOPS

Safety stops are widely considered good diving practice and are an

integral part of most dive tables. Reasons to perform a safety stop in-

clude a reduction in sub clinical DCI, microbubble reduction, ascent

control, and orientation before surfacing.
The Vytec displays two different types of safety stops: Recommended

Safety Stop and Mandatory Safety Stop.
The Safety Stops are indicated by:

- STOP label, when in the depth range 3 m 6 m [10 ft - 20 ft] =

Recommended Safety Stop Countdown

- STOP+ CEILING label, when in the depth range 3 m 6 m

[10 ft - 20 ft] = Mandatory Safety Stop Time display

- STOP label, when deeper than 6 m = Mandatory Safety Stop

scheduled

3.2.1. Recommended Safety Stop

With every dive over 10 meters the instrument has a three minute count-

down for the recommended safety stop, to be taken in the 3 - 6 meter

[10 ft - 20 ft] range. This is shown with the STOP sign and a three-

minute countdown in the center window instead of the no-decompres-

sion time (Fig. 3.11.).
The Recommended Safety Stop, as the name implies, is recommend-

ed. If it is ignored, there is no penalty applied to the following surface

intervals and dives.
