INTRODUCTION
Congratulations on your recent purchase of the Sherwood Wisdom 3 dive computer!
Your new Wisdom 3 uses a unique and intuitive display that represents the information you need before, dur-
ing, and after the dive, laid out in a logical format based on a dive prole diagram. Information is located
where you would expect it to be.
In addition to no-decompression/decompression status, tissue loading of nitrogen, accumulation of oxygen,
and ascent rate are presented as peripheral bar graphs alongside reference indicators.
As you progress through this instruction manual, you will become familiar with the unique functions and fea-
tures available.
The Wisdom 3's wide array of features are described in detail throughout the pages that follow.
The initial time that you invest becoming acquainted with the symbols and various operating modes and dis-
plays will be returned as you enjoy your underwater activities with the comfort that your familiarization af-
fords.
As you use the Wisdom 3, remember that the rules you learned in your SCUBA course(s) still apply to the
diving you will do while using a dive computer - some will become even more important. Technology is no
substitute for common sense, and a dive computer only provides the person using it with data, not the knowl-
edge to use it.
FEATURES AND DISPLAYS
The Wisdom 3 has two Control Buttons that allow you to activate the unit and access specic information
when you choose to see it. The Front button (Fig. 1a) is referred to as the Advance and the Side button (Fig.
1b) as the Select.
While on the surface, you can use the buttons to maneuver through the Wisdom 3's unique Menu System that
allows -
• selection of 3 Main Operating Modes (Air, Nitrox, or Gauge)
• viewing of various information displays (Last Dive, Plan Depths/Times, Dive Logs, History, etc.)
• entering of settings divided into 4 convenient categories (Basics, Alarms, Utilities, and Time)
• activation of the Backlight
• operation of an onboard Simulator
• setup for a PC interface program
During the Dive modes, the buttons may be used to -
• activate the display's Backlight
• view Alternate displays of information
• acknowledge Alarms
INTUITIVE DISPLAYS
The Wisdom 3 uses 4 rows of easy to understand alpha/numeric displays and graphic icons (Fig. 2).
For example, when you enter into Special Situations, such as Decompression, High PO2, and Out of Range
modes, an UP Arrow symbol will appear as a warning to ascend to a shallower depth.
It also utilizes 3 segmented Bar Graphs to provide you with quick visual reference of Decompression status,
O2 Saturation, and Ascent speed. Their segments represent Normal, Caution, and Danger zones.
It is imperative that you understand the formats, ranges, and values of the information presented by the Wis-
dom 3's numeric and graphic displays to avoid any possible misunderstanding that could result in an error.
