HANDSET DISPLAY DETAILS

PRIMARY:

The Primary handset has several informational screens that vary depending on whether

the unit is in surface or dive mode, and if decompression stops are required.

This is the surface mode screen; the top line consists of the

surface interval, selected set-point or open circuit indicator, maximum

depth of previous dive, and finally dive time. The second line is the

current PO reading for each of the three oxygen sensors. The display is updated approximately

every two seconds.

The next display is the first of three screens presented while in

dive mode. The first line displays current depth, selected set-point, dive

time and alternates between maximum depth and measured battery

voltage or battery alarm. The second line displays the PO readings of

the three sensors. If any sensor reading is followed by a “*” that sensor

has been voted out and is not used in the average PO2 calculation. This screen is displayed for

approximately 2 seconds.

The second screen depends on the status of the diver’s

decompression obligation. The top line is the same as on the previous

screen with the change being on the second line. Instead of the PO being displayed, the oxygen

percentage of the selected diluent and “No Stop” is displayed until the diver enters a required

decompression stop. This screen is displayed for approximately 2 seconds.

If there are any required decompression stops, the second screen

have the same first line as the previous two screens, but the second line

now displays the oxygen percentage of the diluent, deepest stop depth

and stop time followed by the total ascent time. The sample screen shows the deepest stop at

20fsw for two minutes and a TTS of 12 minutes. This screen is displayed for approximately 2

seconds.

The third screen may seem like an annoyance, but it serves as a

reminder to the diver. The name of the diluent the diver has selected and

the programmed oxygen percentage of the diluent are displayed on the

second line. This should help insure that the diver doesn’t accidentally use a nitrogen only mix

with same oxygen percentage as a mix containing helium. This screen is displayed for

approximately 2 seconds.
