PATENT NOTICE
U.S. Patents, registered in the U.S. Patent and Trademark Ofce, have been issued to protect the following design features:
Data Sensing and Processing Device (U.S. Patent no. 4,882,678), Dive Time Remaining (U.S. Patent no. 4,586,136), and Ascent Rate Indicator (U.S.
Patent no. 5,156,055).
DECOMPRESSION MODEL
The programs within the AMPHOS simulate the absorption of nitrogen into the body by using a mathematical model. This model is merely a way to apply a
limited set of data to a large range of experiences. The AMPHOS dive computer model is based upon the latest research and experiments in decompression
theory. Still, using the AMPHOS, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression
sickness (i.e., the bends). Every diver’s physiology is different, and can even vary from day to day. No machine can predict how your body will react to
a particular dive prole.

OPERATING MODE STRUCTURE
Unless it is operating in Dive Computer mode, the AMPHOS will be On in the default Watch Main Time (home time) mode (Fig.
1), like a standard watch, until the mode is changed.
The M button is used to access 4 other Modes that include Alternate Time Mode, Countdown Timer, Chronograph (stop watch/
lap timer), and Daily Alarm. It is also used to revert to the Local Default Time display and access Computer Modes.
The screens of the Main Modes and Sub Modes will remain on display until a button is pressed to access another screen or
Mode, activate a sequence, or for 2 minutes if no button is pressed. The Chronograph remains on display as long as it is running
unless another Mode is accessed.
When Wet Activation is set On, the AMPHOS will enter the selected Dive Mode upon descent to 5 FT (feet)/1.5 M (meters) for 5
seconds, regardless of what operating mode it is in.
WARNING: When Wet Activation is set OFF, the AMPHOS must be in Dive Surface Mode (NORM,
GAUG, or FREE) prior to the first dive of a new series. Commencing a dive while in Watch modes will
not activate Dive Mode unless Wet Activation is set ON.
OPERATION AS A DIVE COMPUTER
The AMPHOS 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 breath hold activi-
ties that do not use SCUBA.
NORM and GAUG Modes allow access to Fly, Log, History, and Set Modes.
NORM Mode (only) allows access to Desat Mode.
FREE Mode has it's own group of settings. Shared features such as Backlight duration can be set by accessing NORM or GAUG.
AUDIBLE ALARM
Most warning situations that activate the Audible Alarm while operating in NORM or GAUG Mode will sound 1 beep per second
for 10 seconds, or until the situation is corrected, or it is acknowledged by 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 situa-
tion, or entry into another type of warning situation.
FREE Dive Mode has its own set of Alarms which emit 3 beeps either 1 or 3 times which cannot be acknowledged or set Off.
The Audible will not be active if it is Set OFF (a group A setting).
Situations that will activate the NORM/GAUG 10 second Alarm include -
• Descent deeper than the Max Depth value selected.
• Dive Time Remaining decreases to the value selected.
• Elapsed Dive Time at the value selected.
• High PO2 increases to the value selected.
• O2 reaches 300 OTU (100% of allowed single or daily exposure).
• Nitrogen Bar Graph at the value (segment) selected.
• NORM/GAUG Ascent Rate Alarm - rate exceeds 60 FPM (18 MPM) when deeper than 60 FT (18 M), or 30 FPM (9 MPM)
at 60 FT (18 M) and shallower.
• Entry into Decompression (NORM).

INTRODUCTION
Welcome to Sherwood and thank you for choosing the AMPHOS !
It is extremely important that you read this Owner's Manual in sequence and understand it completely before attempting to use
the AMPHOS as a dive computer.
Remember that technology is no substitute for common sense, and a dive computer only provides the person using it with data,
not the knowledge to use it.
CONTROL BUTTONS
The AMPHOS features 4 Control Buttons that allow you to select mode options and access specific information. They are also
used to enter Settings, activate the Backlight, and acknowledge the Audible Alarm.
Throughout this manual they will be referred to as the M, S, L, and A buttons.
• Upper/Left - Mode (M) button
• Upper/Right - Select (S) button
• Lower/Right - Light (L) button
• Lower/Left - Advance (A) button

• Conditional Violation (above a required Deco Stop Depth for less than 5 minutes).
• Delayed Violation (above a required Deco Stop Depth for more than 5 minutes).
• Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required).
• Delayed Violation (Maximum Operating Depth of 330 FT/100 M is exceeded).
• A Gas Switch to another tank would expose the diver to PO2 greater than 1.60 ATA.
• Watch Daily Alarm reaches time set (on surface only).
• Watch Countdown Timer reaches 0:00 (on surface only).
A single short beep (which cannot be disabled) is emitted for the following -
• Upon completion of a battery change.
• Change from Delayed to Full Violation 5 minutes after the dive.
3 short beeps (which cannot be disabled) are emitted for the following -
• NORM/GAUG Ascent Rate Warning - rate is 51 to 60 FPM (15.1 to 18 MPM) when deeper than 60 FT (18 M), or 26 to
30 FPM (7.5 to 9 MPM) at 60 FT (18 M) and shallower.
• FREE Dive Elapsed Dive Time Alarm - 3 beeps at each 30 second interval, if set On.
• FREE Dive Depth Alarms 1/2/3 (set sequentially deeper) - each 3 beeps 3 times.
• FREE Dive NIBG Alarm (Caution zone, 4 segments) - 3 beeps 3 times.
• Entry into Deco during a FREE Dive (Violation) - 3 beeps 3 times.
• Free Mode Countdown Timer reaches 0:00 - 3 beeps 3 times.
During the following NORM Dive situations, the 10 second continuous tone will be followed by a 5 second steady beep that
cannot be acknowledged/silenced -
• Ascending above a required Decompression Stop Depth for more than 5 minutes (referred to as a Delayed Violation).
• Decompression requires a Stop Depth of 70 FT (21 M) or deeper.
• Being on the Surface for 5 minutes after a Conditional Violation.
BACKLIGHT
To activate the Backlight, press the L (lower/right) button.
• The Backlight will activate and illuminate the display for button depression time* plus the Duration time set (0, 5, or 10
seconds) for a maximum of 20 seconds.
*The Backlight turns Off if the button is held depressed for more than 10 seconds.
• Press L again to activate as desired.
NOTE: Extensive use of the Backlight reduces estimated Battery life. Also, the Backlight does not
operate during a Low Battery condition or when the AMPHOS is connected to a PC.
POWER SUPPLY
The AMPHOS uses (1) 3 volt CR2430 Lithium Battery. Used as a Dive Computer, the battery should operate normally for 1 year
or 300 dive hours if 2 dives are conducted during each dive period. Voltage is checked every 2 minutes on the surface.
• If voltage decreases to the Warning level (2.75 volts), the Battery icon will appear on Surface Main (Fig. 3a) as an
indication that the Battery should be changed prior to commencing a series of dives.
• If the voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and the message CHANGE BATT will flash
(Fig. 4) for 5 seconds, then operation will revert to Watch Main Time. The AMPHOS would then only operate in Watch
modes until the Battery becomes completely depleted.
• Low Battery conditions are not displayed during dives.
• If a Low Battery Condition was not displayed prior to starting a Dive, and a Low Battery Condition occurs during the dive,
there will be sufficient Battery power remaining to maintain operation for the remainder of that dive.

WARNING
a
• It should not be considered that the capabilities built into the AMPHOS provide an implied approval or consent from Sherwood for indi-
viduals to exceed the dened limits for recreational diving, as agreed on by all internationally recognized training agencies.
• The oxygen features of the AMPHOS are intended for use by recreational divers trained for Nitrox diving by an instructor certied by a
recognized training agency to teach diving with Nitrox.
• Conducting repetitive dives using enriched nitrogen-oxygen mixtures can lead to oxygen buildup, reducing oxygen tolerance while in-
creasing the risk of pulmonary oxygen toxicity.
• The AMPHOS provides information based upon a personal dive prole, and therefore must not be shared between divers. It is impossible
for two divers to stay precisely together underwater, and your computer's dive prole tracking of previous dives will be pertinent to you
only. Nitrogen and oxygen loading of a second user may be signicantly different and swapping dive computers could lead to inaccurate
and dangerous predictions of decompression and oxygen accumulation status.
