Changing Units of Measurement: While in Date/Time Set
Mode, you can also change the how the IQ-600 displays depth
and water temperature. Simply press and hold buttons A and B
for 30 seconds. You will hear the computer’s audible alarm
sound. This signifies that the computer has switched from dis-
playing data in feet and degrees Fahrenheit to meters and
degrees Centigrade (or vice versa).
To exit this mode: You may exit Date/Time Set Mode in a
variety of ways:
Return to Surface Mode—To do so, simply complete the
process of scrolling through and, if necessary, changing all
the various date and time settings. You will return to
Surface Mode automatically.
Go Diving—Taking the IQ-600 under water will cause it to
automatically leave Date/Time Set Mode and enter Dive
Mode.
Do Nothing—If you take no further action while in
Date/Time Set Mode, the IQ-600 will return automatically
to Surface Mode within five to six minutes.
2.06 Dive Mode
Among the IQ-600’s key features is the fact it enters Dive Mode
automatically upon descent. As discussed previously, we strongly
recommend accessing your IQ-600’s Dive Plan Mode prior to
descending, so that you may double check that: it is functioning
properly; the date and time settings are correct; and, the dive you
are planning falls well within the available No-Decompression
Limits (NDLs). Nevertheless, your IQ-600 will not “lock up” nor
make erroneous assumptions regarding altitude or depth if you
fail to do so.
