36 COURIER OWNER’S MANUAL

■■Remember that the Courier does not monitor breathing

gas supply. You must monitor this yourself, on every

dive, using a submersible pressure gauge or equivalent

device.

■■Do not rely solely on this—or any other—dive comput-

er. Take a back-up dive computer or tables (along with

a separate means of monitoring depth and dive time).

■■Be aware that the Courier makes assumptions regard-

ing residual nitrogen based on altitude settings. Avoid

making abrupt changes in altitude following a dive, as

doing so may be very dangerous.

■■The Courier does not have a “Time to Fly” function.

We recommend you follow current medical recommen-

dations for flying after diving, or wait until the Courier is

capable of re-entering Sleep Mode (whichever is longer)

before flying in an aircraft or driving to a higher alti-

tude.

4.0 Care and Maintenance

This section covers the general care and maintenance

procedures you should follow before, after and between

dives, and the procedure for changing batteries. General

maintenance procedures include:

■■Rinse the Courier thoroughly in fresh water following

every dive.

■■Do not use cleansers, chemicals or solvent to clean the

Courier. Use a soft cloth to gently wipe dirt or water

stains from the computer.

■■The glass display may be damaged (and its water resis-

tance impaired) if exposed to: solvents such as alcohol

or gasoline; cosmetic products such as hair spray or liq-

uid soaps; alkaline substances; aromatic hydrocarbon

solvents; and, halogenated hydrocarbon solvents.

■■Store the Courier in a cool, dry location. After diving,

wipe the computer dry and store it in a location sepa-

rate from other damp items.

Battery Replacement

You should replace the battery in your Courier whenever

the Low Battery warning symbol, described earlier in this

manual, appears. If you encounter any other problems

with your Courier that you suspect, but are not certain,

may be caused by a low battery, consult an authorized

Sherwood dealer. Your Sherwood dealer may also replace

the battery for you, if you do not feel comfortable doing

so yourself.

What you will need—Before beginning the battery

replacement procedure outlined here, make certain you

have the following items ready.

■■

A replacement battery (obtainable from authorized

Sherwood dealers)

■■

Silicone grease (the type normally used in scuba equip-

ment service).

■■

Paper towels, or—better still—lint-free industrial wiping

cloths

■■Cotton swabs

■■

Denatured alcohol (use in conjunction with cotton

swabs to remove unwanted deposits of dirt and grease

■■A pencil with an erase tip in good condition

■■A large coin

You should also have at your disposal a suitable working

area. This area should be clean and well lit, and as far

away as possible from excessive moisture and wind-

blown sand, dirt, rain or salt spray. A dive boat is not a

good place change your Courier’s battery.

Replacement procedures—Here are the steps to follow

to replace your Courier’s battery, using the items

described above.

1 Begin by removing the Courier from its console boot.

To do so with the Sherwood CNC-3™ console, first pull

the submersible pressure gauge partially out of the con-

sole, as shown in Figure 12. Now place your thumb

inside the hole normally occupied by the pressure gauge

and use it to push the computer module out.

Figure 12: Procedure for removing Courier from its con-

sole.

2 Turn the Courier face down to expose its battery com-

partment door, as shown in Figure 13.

the location of its battery compartment door.

3 Using a large coin, remove the battery compartment

door by turning it in a counterclockwise direction.

4 Note the condition of the old battery and battery com-

partment. If you detect any signs of leakage, such as a

build up of corrosion, remove—but do not replace—the

old battery. Instead, take the Courier to an authorized

Sherwood dealer for further service.

5 If the old battery appears in good condition, remove it

by turning the computer module right side up, and

allowing the battery to drop out.

6 Clean the battery contacts using the pencil eraser. If

you detect any build up of dirt or grease in the area

where the compartment door O-ring makes contact,

remove it using a cotton swab soaked in a small amount

of denatured alcohol.
