2. GETTING ACQUAINTED
2.1. FUNCTIONS
The VYPER multipurpose dive computer features three dive computer models
(AIR, NITROX, GAUGE), three main operating modes (TIME/STAND-BY,
SURFACE, DIVING), three menu based main modes (MEMORY, SIMULATION,
SET) and 15 - 17 menu based submodes (see fi gure in the back cover). You can
scroll through the modes using the push buttons. The mode indicator at the left
side and the mode text at the bottom of the display indicate the selected mode.
You can select the dive computer model between the Regular Air Dive
Computer, Enriched Air Dive Computer and Depth Gauge and Timer modes.
The timekeeping display is the primary display of the instrument (Fig. 2.1).
In other Modes (except in the Diving or Simulator Modes), if no button is
operated within 5 minutes, the dive computer beeps and returns to the time-
keeping display automatically. The timekeeping display shuts off after two
hours, but pressing the PLAN or TIME button activates it.
When diving, the dive entry time and date is registered in the Logbook Memory.
Remember always to check before diving that the time and date are correctly set,
especially when traveling to different time zones. To set the time and date, refer
to section 4.3.2. "Setting Time".
2.2. PUSH BUTTONS
The dive computer has easy-to-use push buttons and an advising display, which
guides the user. The SMART (MODE) button is the key of the system. The two
scroll buttons, PLAN and TIME, are used for scrolling up and down the menus
and to get the alternative displays visible. The dive computer is controlled with
these three push buttons as follows (see Fig. 2.2).
