DIVE OPERATION

COMPLICATIONS
The preceding information has described stress free casual dive operations. Your new i300C is also designed
to help you to the surface in less than ideal situations. The following is a description of these. Take some time to
familiarize yourself with these operations before diving your i300C.
DECOMPRESSION
Decompression mode activates when theoretical No Decompression time and depth limits are exceeded. Upon
entry into Deco, the audible alarm will sound and the alarm LED will flash. The full N2 bar Graph and Up Arrow
icon will flash until the audible alarm is silenced.
> Once within 10 FT (3 M) below the required Stop Depth (stop zone), the Full Stop icon (both Arrows with Stop
Bar) will be displayed solid.
To fulfill your decompression obligation, you should make a safe controlled ascent to a depth slightly deeper than,
or equal to, the required stop depth indicated and decompress for the stop time indicated. The amount of decom-
pression credit time that you receive is dependent on Depth, with slightly less credit given the deeper you are be-
low the Stop Depth indicated. You should stay slightly deeper than the required Stop Depth indicated until the next
shallower Stop Depth appears. Then, you can slowly ascend to, but not shallower than that indicated Stop Depth.
GAS SWITCH WARNING
If gas 2 is set on and the current gas is not the best gas when approaching the decompression stop zone, the
i300C will warn you to switch gases. You must confirm the gas switch by pressing the SEL button. If the gas
switch is not confirmed within 30 seconds, no switch will be made. Though you may still manually switch gases at
any time throughout the dive by using the Gas Switch menu.

DECOMPRESSION ENTRY
Upon entry into decompression the audible alarm will sound and the alarm LED will flash until the audible alarm
is silenced. The message UP, Up Arrow, and full N2 Bar Graph icons will flash. Additionally, the stop depth, stop
time, and the TTS (Time To Surface) values will be displayed. TTS includes stop times at all required Decompres-
sion Stops plus vertical ascent time based on the max rate allowed.
