1.0 Introduction
This information has been developed for your safety.
Please read and understand this manual completely
before using your new Sherwood dive computer.
1.1 Simply Reliable
Congratulations! You are now the owner of a new
Sherwood Scuba dive computer. You’re about to experi-
ence the Sherwood difference in diving equipment—
products that are simply reliable. At Sherwood, we
focus on the type of diving you do, then design products
that address your specific needs. The simple, purposeful
designs of all Sherwood equipment provide you with reli-
able, trouble-free performance, dive after dive.
1.2 Key Features
Among the Courier’s key features:
■■The Courier fits Sherwood’s CNC-3™ Compact
Navigational Console. This console combines the
Courier with an analog submersible pressure gauge
(SPG) and easy-to-use top- and side-reading compass.
The console also features clip anchors on either side, to
help attach it to your BC. The Courier computer mod-
ule will also fit in most other standard instrument con-
soles and circular wrist mounts.
â– â– The Courier activates automatically upon descent. It
need not be manually activated prior to entering the
water (although we recommend doing so).
â– â– It automatically adjusts for altitudes up to 7,882
ft/2,400 m, and is capable of functioning at depths up
to 328 ft/100 m.
COURIER OWNER’SMANUAL 5
â– â– The Courier displays a variety of data, including date,
time of day, current, max and average depths, no-
decompression dive time elapsed and remaining, and
water temperature.
â– â– The Courier provides visible alarms for violation of
ascent rate, no-decompression status and mandatory
decompression stops.
â– â– If needed, the Courier can calculate deco requirements
for stops as deep as 39 ft/12 m.
■■The Courier’s Random Access Memory (RAM) enables it
to hold and display log data on ten dives.
■■Depending on use, the Courier’s battery can last up to
several years before needing replacement. Battery
replacement may be done by an authorized Sherwood
dealer, or by the consumer, following the instructions
appearing in this manual.
1.3 Common Sense Warnings
As is true of every piece of diving equipment—including
all dive computers—the Courier’s abilities are not limitless.
Thus, there are certain limitations and restrictions of
which you must be aware, and certain precautions you
must take, when using the Courier.
Before using your Courier, it is extremely
important you read the following points—as
well as similar warning and caution notices
that appear throughout this manual—and fol-
low the recommendations they provide.
Failure to do so could result in damage to or
loss of equipment, serious personal injury
or death.
6COURIER OWNER’SMANUAL
â– â– The Courier is designed for use by certified, recreational
divers who have maintained a sufficient level of knowl-
edge and skill proficiency through a combination of for-
mal training, ongoing study and experience. It is not
intended for use by persons who lack these qualifica-
tions and, thus, may not be able to identify, assess and
manage the risks scuba diving entails.
â– â– The Courier is not intended for use by commercial, mili-
tary or technical divers, whose activities may take them
beyond the commonly accepted depth limits for recre-
ational diving.
â– â– The Courier is designed for use by divers breathing nor-
mal compressed air. It does not provide a means of
tracking exposure to the elevated partial pressures
divers may encounter when breathing Enriched Air
Nitrox (EANx).
â– â– Although the Courier is capable of calculating decom-
pression stop requirements, this ability is provided as a
safety feature only, should recreational divers accidental-
ly exceed the No-Decompression Limits (NDLs). Dives
requiring mandatory stage decompression carry sub-
stantially greater risk than dives made well within no-
decompression limits. Divers should not use the Courier
to plan or execute dives that will intentionally exceed
no-decompression limits.
â– â– The Courier is designed to be used by only one diver at
a time. Divers should not share a single Courier—or
any other dive computer—on the same dive.
Additionally, no diver should lend his or her Courier to
anyone else until it calculates that no measurable resid-
ual nitrogen remains after previous dives, and is able to
enter its Sleep Mode. Further, no diver should use his or
her Courier for repetitive dives—unless that same
Courier has accompanied him or her on all previous
dives in the same repetitive dive series.
COURIER OWNER’SMANUAL 7
■■Neither the Courier—nor any other dive computer
presently available—physically measures the amount of
nitrogen present in body tissues, or the rate at which
this nitrogen is being absorbed or released. Instead, the
Courier monitors depth and time, and uses this data to
work a mathematical formula designed to emulate how
individuals in good general health and whose physical
characteristics do not place them among those at high-
er risk of decompression illness are assumed to absorb
and release nitrogen from body tissues. Thus, the
Courier cannot compensate for factors such as age,
obesity, dehydration, cold or exertion, which experts
believe place divers at greater risk of DCI. If these, or
similar factors apply to you, use the Courier—and any
other dive computer or dive table—with even greater
caution.
â– â– Experts still know surprisingly little regarding the exact
nature and causes of decompression illness (also known
as decompression sickness, DCI or DCS). Susceptibility to
DCI may vary substantially from person to person and
from day to day. Neither the Courier—nor any other
dive table or dive computers—can guarantee that you
will not suffer decompression illness. Even though you
use these items correctly, you may still suffer DCI. Use
your Courier conservatively, and in conjunction with
other dive planning devices, such as dive tables. Do not
rely on the Courier, or any similar device, as your sole
means of avoiding decompression illness.

2.0 Using the Courier
The key to using the Courier correctly is learning to
access, recognize and interpret the data presented in its
various display modes. The Courier is capable of display-
ing far more data than can fit in a single screen. Thus, to
help avoid confusion, it displays only that data which is
relevant to a particular situation. For example, the data
appearing when the Courier is in its Date/Time Set Mode
is very different from that appearing when it is in Dive or
Deco Mode.
The Courier is capable of presenting ten different dis-
play modes. In the balance of this manual, we will identi-
fy each of these modes, and explain:
â– â– What the purpose of each mode is.
â– â– How you enter and exit each mode.
â– â– What data you will see in each mode, and how to
interpret it.
â– â– What visible warnings may be displayed in each mode,
and how to respond to them.
2.1 Accessing Display Modes
There are some display modes that the Courier enters
and/or exits automatically. For example, by taking the
Courier under water, you automatically activate its Dive
Mode. After sufficient inactivity, your Courier will automat-
ically enter its Sleep (Battery Saver) Mode.
To access other modes, you may need to push one of
the two large, red buttons appearing on the Courier’s
face. These are the A(Plan) and B(Log) buttons.
COURIER OWNER’SMANUAL 9
Figure 1: The front of the Courier, showing its Liquid
Crystal Display (LCD) in Check Mode, and the two large
A (Plan) and B (Log) buttons.
You will find both buttons easy to use. In some instances,
you may need only press a button once and release it to
achieve the desired result. In other instances, you may
need to hold the button down until you get the result
you wish. This manual will outline clearly which proce-
dure to follow for each mode or task.
2.2 Sleep (Battery Saver) Mode
So long as there is sufficient battery voltage, your Courier
never turns completely off. Even when it appears to be
“asleep,” the Courier monitors factors such as battery volt-
age and altitude. Nevertheless, to prolong battery life,
your Courier is programmed to project data on its Liquid
Crystal Display (LCD) only when absolutely necessary.

Figure 2: Sleep (Battery Saver) Mode.
To enter this mode: There is actually nothing you can
do to force your Courier into Sleep Mode. If you have
activated your Courier—but not taken it diving—it will
return automatically to Sleep Mode after five to six min-
utes. If, on the other hand, your Courier calculates that
there is still residual nitrogen present from previous dives,
it will not enter Sleep Mode until it determines that all
residual nitrogen is effectively gone.
What you will see: When the Courier is in Sleep Mode,
its Liquid Crystal Display (LCD) will normally be blank, as it
appears in Figure 2.
Warnings you may encounter: As shown in Figure 2,
there is one warning that may appear, even though the
rest of the Courier is “asleep.” This is the Low Battery
warning. This warning may or may not blink on and off.
The Low Battery warning means that the Courier’s battery
lacks sufficient voltage to function properly.
Once the Low Battery warning appears, it will remain
visible in all display modes except Log Mode. Additionally,
the presence of the Low Battery warning will prevent the
Courier from entering Dive Mode—a feature designed to
help prevent the Courier from failing under water.

COURIER OWNER’SMANUAL 11
Once the Low Battery warning appears, you
must return your Courier to your local autho-
rized Sherwood distributor for battery replace-
ment, or replace the battery yourself, following
the procedures outlined later in this manual.
Before replacing your Courier’s battery, be sure
to copy all dive log data to your log book, as
the battery replacement process erases all such
data from the Courier’s Random Access
Memory (RAM).
The battery that comes with your Courier is designed to
last up to several years under normal use. Several factors
may affect battery life; therefore, do not be surprised if
you get significantly more or less use from your Courier’s
battery.
To exit this mode: You can exit Sleep Mode (i.e, cause
your Courier to “wake up”) by pressing either the Aor B
buttons, or by taking it under water.
2.3 Check Mode
When you “awaken” your Courier from Sleep Mode, the
first thing it will do is enter Check Mode. In this mode,
the Courier projects its full segment display. Check Mode
provides you with the opportunity to test your Courier for
proper function before taking it under water.
To enter this mode: From Sleep Mode, press either the
Aor Bbutton, or take it under water.
What you will see: As shown in Figure 3, all pixels (pic-
ture elements) on your Courier’s Liquid Crystal Display
(LCD) should appear clearly during Check Mode.
