Sampling (Sample Rate); Tmt Menu (Transmitter Menu) - Aqua Lung i450T Owner's Manual

8. SAMPLING (SAMPLE RATE)

The Sample Rate controls how frequently the i450T stores a data snapshot for PC Download
during a dive. Setting options are 2, 15, 30, or 60 second intervals. Shorter intervals will provide a
more precise record of your dives.
NOTE: New data will automatically overwrite the oldest data in memory when the memory
becomes full. The i450T Log and PC Download data is stored separately in different parti-
tions of the memory. The Log only stores a short summary of each dive. Alternately, the PC
Download function stores much larger files for each dive. Depending on the chosen set-
tings and dive durations, it is possible to see dives stored in the i450T's onboard Log that
have already been overwritten in the PC Download Partition. Choosing a longer Sample
Rate interval will consume less memory per dive. Remember to download your dives more
frequently if you are using a shorter Sample Rate interval.

9. TMT MENU (TRANSMITTER MENU)

The i450T can use up to 3 transmitters to monitor gas supplies. The TMT Menu allows for the pro-
gramming of the wrist unit to receive the signals from selected Aqua Lung transmitters. See the
Dive Mode Features section (p. 24) for further information on transmitters.
NOTE: If the TMT is set OFF for the active gas, the letters SPG will be displayed in place of
a pressure reading on the Main Screen.
NOTE: Transmitter 2 cannot be set to ON unless transmitter 1 is set to ON. Likewise, tran-
mitter 3 cannot be set to ON unless transmitter 2 is also set ON. If you attempt to do so, the
i450T will display the message TMT 1(2) MUST BE SET ON FIRST.
