What happens next depends on how the system is initially powered up. If it is powered-up by
battery insertion with a turned on M28, then the first screen displayed shows the SE7EN mode
display (Figure 2-2) for a few seconds before switching automatically to initiate the PreDiveTest
mode. (Figure 2-3). The firmware version number is shown in the upper left area underneath
the open circuit bail out icon together with the unit serial number. Because the SE7EN and the
M28 are designed to accept firmware updates, knowing the specific version number of the
firmware is extremely important when diagnosing problems.
SE7EN Power-Up through the M28
The M28 can be individually powered-up by a brief push at both
buttons simultaneously (Figure 2-1), the SELECT command, a
green LED vill become visible, followed by a Poseidon welcome
screen and further to the “land veiw”. Use the two buttons to
navigate to the app “Dive” . Select “Dive mode” and further select
“Start SE7EN”. The electronics will now initiate the pre dive test
(Figure 2-3) if the battery is inserted into the SE7EN. Please
consult the M28 main manual for further information concing
menus etc.
