For example, after changing the battery, you will see one of these two screens:
Normally you should see the confirmation that the controller restored the tissues status. Conditions that
cause the tissues to be cleared are:
Firmware Updates:
A Firmware update will clear the tissues. Therefore, updating the firmare in the mid-
dle of a dive trip is not a good idea.
Slow Battery Change:
Quick battery changes do not normally cause the tissues to be cleared. A super
capacitor stores energy to keep the clock running for at least 15 minutes during a battery change. If
battery removed for longer than 15 minutes, then the tissues will be cleared.
User request:
You can clear the tissues manually in the “System Setup” menu. Use the Reset To Defaults
option. This will then prompt if you want to reset the settings only, the tissues only, or both.
Corruption:
A 32- bit cyclic redundancy check (CRC) is used to verify the integrity of the tissues each time
the controller is turned on. If corrupted, the tissues will be cleared. The most likely cause of corruption is
removing the battery with the controller turned on. Therefore, turning the controller off before changing
the battery is the best practice.
6. Confirm inserted battey type, time and date, calibrate compass:
The controller tries to auto-
matically recognize the inserted battery type by its voltage. If the controller displays the wrong bat-
tery type, you can manually change it.
•
Having the battery type set correctly is important so that the controller can give low battery warnings
at the proper voltage levels..
The next screen shows the time and date. Should they be wrong, you can manually change them. The last
screen allows to calibrate the compass. This should be done after every battery change.
