Page: 63 / 88

Units:

Display of depth and temperature

in metric (m/°C) or imperial (ft/°F) units.

Sampling rate

: the sampling rate is

adjustable from 2 to 10 seconds.

Salinity:

This setting allows you to adjust

salinity of water, used for calculating the

actual and maximum depth. The default

salinity is 0%. To increase this value,

select the

salinity

menu and press ENTER

repeatedly until the required value is

displayed. The value range is from 0% to

4%.

Note

Decompression information is based on

absolute pressure and not on relative

pressure. Therefore salinity does not

effect this calculation.
