Nitrox reset time
If you are generally diving with air and want
to return to this setting after occasional
nitrox dive, you can preset a default time
when your Chromis will reset back to air.
By pressing SEL button the time at the
top row starts blinking. The time can be
selected from 1 hour up to 48 hours or
the nitrox reset time can be disabled by
pr or - buttons. Gas reset time is
disabled when - - h is shown.
4.2.3
Desaturation reset
WARNING:
Resetting desaturation will effect calculations
of the algorithm and this may lead to serious
injury or fatal injury. Do not reset desaturation
without a solid purpose.
When Chromis is still counting down the
desaturation, some menu changes are not
possible. In case the user decides to reset
the desaturation, the safety code 313 must
be given. This procedure secures unwanted
resetting and the desaturation reset will be
stored to a memory. At the next dive log the
desaturation symbol will be shown.
By pressing SEL button the selection ‘on’
starts blinking. By pr or - buttons
the desaturation can be deactivated and the
state is indicated with selection ‘off’. When
off state is confi rmed by pressing SEL button
the code page appears. The fi rst digit starts
blinking and by pr/- this can be
edited. By pressing SEL button the number
is confi rmed and the next number starts
blinking. When code is given correctly and it
is confi rmed with the SEL button press then
the desaturation reset is completed.
