2.05 Date/Time Set Mode
Prior to using your IQ-600 under water, you will not only
want to check its FO
2
setting, but also that it displays the cor-
rect date and time. Doing so not only enables you to use the
IQ-600 as a timepiece, it further helps ensure that the date and
time data displayed when the computer is in Log and Profile
Modes are accurate.
When you first use your IQ-600, you will most likely dis-
cover that the month, day and minute are already correct; how-
ever, depending on your time zone, the hour may not be.
To enter this mode: From Surface Mode, press and hold but-
tons A and B for at least five seconds (be aware, however, that
you cannot access Date/Time Set Mode within ten minutes of
surfacing from a dive).
What you will see: Upon accessing Date/Time Set Mode,
your IQ-600’s display should appear exactly as shown in
Figure 7. The digits representing the current hour (based on
the 24-hour clock) will be blinking.
To change the hour, simply press the
B
button. Each time you
do so, the number shown will advance by one. If you press
and hold the
B
button, the numbers displayed will advance
rapidly. If you accidentally go past the number you were
shooting for, simply continue; you will cycle back through to
the number desired.
