Figure 3: Check Mode.

Warnings you may encounter: There are no specific

warnings that appear during Check Mode; however, you

should examine the display carefully to make certain

all pixels appear clearly.

If all pixels do not appear clearly during Check

Mode, do not take your Courier diving.

Instead, you should return it to an authorized

Sherwood dealer for immediate service. Failure

to do so could result in damage to or loss of

equipment, serious personal injury or

death.

Although it is possible to take your Courier diving without

first activating it on land, we do not recommend this.

Instead, you should “awaken” your Courier first (by press-

ing either the A or B buttons), then observe it in Check

Mode to help ascertain that everything is functioning

properly. If you do not do so, it is theoretically possible

that your Courier could give you erroneous information

under water, and you would not be aware that it was

doing so.

To exit this mode: Within two to three seconds of

entering Check Mode, your Courier should automatically

enter either Surface or Dive Mode, depending on

whether you activated the computer by pressing its A or

B buttons, or by taking it under water.

2.4 Surface Mode

Assuming that you follow the recommended procedure

of activating and checking your Courier before taking it

under water, it will remain in Check mode for from two

to three seconds, then enter Surface Mode. Your Courier

will also enter Surface mode immediately upon ascend-

ing from any dive.

Figure 4: Surface Mode.

To enter this mode: There is no specific action you

must take to get your Courier to enter Surface Mode—

other than to press its A or B buttons if it is “asleep.” You

will discover that Surface Mode is the Courier’s default

mode whenever it is “awake” and not under water.

14 COURIER OWNER’S MANUAL

What you will see: If your Courier does not calculate

that there is residual nitrogen present from previous dives,

it will display only the current date and time.

■■Date Format—The format the Courier uses to display

the current date is that common in the USA and Japan,

in which the first set of one or two digits signifies the

month, and the second set of one or two digits (follow-

ing the hyphen) signifies the day. Thus, a date of 11-3

would represent the third of November.

■■Time Format—The Courier uses the 24-hour clock for-

mat, common in aviation and military service, to signify

time of day. Thus, a displayed time of 13:04 would

represent 1:04 PM.

If your Courier calculates that there is residual nitrogen

present from previous dives, it will also display the Surface

Interval Time (SURF T.) that has elapsed since ascending,

and a symbolic representation of the overall quantity pre-

sent on its Residual Nitrogen Bar Graph.

■■“SURF T.” Format—The format your Courier uses to dis-

play Surface Interval Time (SURF T.) is HOURS:MINUTES.

COURIER OWNER’S MANUAL 15

■■Residual Nitrogen Bar Graph—This is a row of nine

pixels that represents the overall saturation of body tis-

sues with nitrogen. When all nine pixels appear under

water, it means you have reached (or exceeded) the

No-Decompression Limit (NDL). On the surface, fewer

than nine pixels should appear, and the number of pix-

els appearing should diminish over time—as the level of

excess nitrogen present in your system diminishes as

your Surface Interval Time passes.

One of the greatest benefits of this symbolic representa-

tion of nitrogen levels during surface intervals is that it

helps you decide how long to wait before re-entering the

water. For example, should you elect to make a repetitive

dive when there are more than just a few pixels appear-

ing, you will discover that your available no-decompres-

sion dive time ends up being very short. Thus, it makes

sense to wait until fewer pixels appear, and you can en-

joy longer bottom times with a greater margin of safety.

If you are more than 2,624 ft/800m above sea level,

your Courier will also display its current altitude settings.

We will discuss these shortly.

Warnings you may encounter: There are none—other

than the Low Battery Indicator discussed earlier.

To exit this mode: You can exit Surface Mode in a vari-

ety of ways. Among them:

■■Allow Your Courier to go “Back to Sleep”—If you

have awakened your Courier from Sleep Mode and

take no further action within five to six minutes, it will

return to Sleep Mode automatically. If your Courier has

been under water in the past 24 hours, it will also go

“back to sleep” once it calculates that there is no longer

residual nitrogen present.
