●
Time – the time of day at which you entered the water
●
Min. Temp. – minimum temperature over the whole duration of the dive
●
Max. Temp. – maximum temperature over the whole duration of the dive
●
Surf. Int. – the surface interval since last dive
●
CNS start – the central nervous system oxygen saturation, in percent, at the beginning of the
dive
●
CNS finish – the same value at the end of the dive
●
OTU – oxygen toxicity units acquired throughout the duration of this dive
●
Depth Graph – by choosing this option, you will see depth profile of your dive
●
Temp. Graph – by choosing this option, you will see temperature profile
The depth graph spans whole width of the screen, with the start of the dive at the left-most part, and the
end of dive at the right-most part. The top of the screen represents the surface of the water, and the
bottom of the screen represents the maximum depth reached (this number is also printed on the screen).
By tapping, you exit back into the “Log Detail” menu.
5.3. Depth Graph
The temperature graph also spans whole width of the screen, with start of dive at the left-most part, and
the end of dive at the right-most part. There are two numbers printed on the screen, one in bottom-left –
that is temperature represented at the bottom of the screen, and one in top-left – that is temperature
represented at the top of the screen. By tapping, you exit back to the “Log Detail” menu.
5.4. Temperature Graph
This is a series of settings you can use to personalize your XEO’s display.
6. Display Settings
The “Brightness” setting has three levels – low, medium and high. The darker the water, the lower
brightness you need to see your display clearly. Also, you might find high brightness in the dark water
too bright – that is, it could emit too much light, compared to environment you're diving in. On the
other hand, in clear, shallow water, with lots of sunlight, you will need high brightness to see the
display properly. Keep in mind that higher brightness burns more battery, so you should select the
lowest brightness that meets your needs on a given dive.
6.1. Brightness
You can use the “Auto Dim” feature to fine-tune the brightness of your display. If you need high
brightness on the surface and lower brightness at depth, you do not need to adjust it manually. Instead,
you can set your “Auto Dim” setting to the depth at which you want your display brightness to be
reduced to Low. By using the “Auto Dim” feature, here is what will happen:
6.2. Auto Dim
●
At the surface, display brightness will be at the setting chosen in the “Brightness” menu
●
Once you reach your Auto Dim depth, and below, the brightness will switch to Low
●
Between these two, the brightness will decrease linearly with depth (e.g., at half of the Auto
Dim depth, it will be halfway between the surface brightness setting, and Low)
If you set your Brightness setting to “Low”, the Auto Dim feature will have no effect.
The default Auto Dim setting is “Off”. You can adjust it in 10m / 30ft increments.
