How to read the data on the display

Dive time – Cumulative dive time from the beginning

of the descent . Time begins to count down when the

diver descends to a depth of 1 .5 m

Depth (m or ft) – current depth in meters or feet

according to Liberty settings

SP – currently used ppO

setpoint .

Compass accuracy – if the compass accuracy is

low, an exclamation mark will appear at the bottom

left of the screen with a text warning about the low

compass accuracy

Battery capacity – graphically displays the battery status in the Liberty head . The colour of the

battery changes from green through yellow and orange to red .

pO2 – current oxygen partial pressure averaged from all active oxygen sensors .

TTS – Time to surface . Cumulative time required to surface . Includes ascent time and time at

decompression stops .

Ceiling – Decompression ceiling indicates the depth that the diver must not exceed when

ascending to prevent the excessive formation of bubbles in the body, which could lead to the

outbreak of decompression sickness .

Heading – current direction

Compass – compass rose with indication of basic azimuths, world sides and current course .

Graphical representation of sensor deviation – Each individual oxygen sensor is represented by

one bar of the graph . The value of the sensor corresponds to the height of the graph, which can

be read approximately from the scale on the right . One scale division represents 0 .2 bar ppO

large scale divisions are by 1 . 0 bar . Hyperoxic values are shown in red, hypoxic values in blue .
