3. Bluetooth SMART Pairing
To transfer dive logs, download the TUSA Diving LOG app on your smartphone or tablet. Follow the app's instructions to pair your device with the IQ-1204 via Bluetooth SMART technology.
Operating Modes
The IQ-1204 features several operating modes accessible via the MODE button.
1. Dive Mode
This is the primary mode for diving. It automatically activates when submerged and displays critical dive information such as current depth, dive time, no-decompression limit, and ascent rate. The computer uses the AA Buhrmann ZHL-16C Decompression algorithm for calculations.
2. Gauge Mode
In Gauge Mode, the computer functions as a bottom timer, displaying current depth, dive time, and temperature. Decompression calculations are disabled in this mode, requiring the diver to manage decompression manually.
3. Free-Dive Mode
Optimized for freediving, this mode tracks maximum depth, dive time, and surface interval. It provides specific alarms and data relevant to freediving activities.
4. Log Mode
Access your stored dive history. The computer records details of your previous dives, which can be reviewed on the device or transferred to the TUSA Diving LOG app.
5. Plan Mode
Use Plan Mode to simulate no-decompression limits for various depths and bottom times. This helps in planning safe dives before entering the water.
Dive Planning
The Plan Mode allows you to simulate dives to determine no-decompression limits. To use:
- From the surface interval display, press the PLAN button.
- Use the ADJUST or LOG buttons to scroll through different depths.
- The display will show the corresponding no-decompression limit for each depth.
- Press PLAN again to exit.
Dive Log Transfer
The TUSA IQ-1204 can transfer dive log data to compatible smartphones or tablets using Bluetooth SMART technology. This requires the TUSA Diving LOG app, available for download from your device's app store.
- Ensure Bluetooth is enabled on your smartphone/tablet.
- Open the TUSA Diving LOG app.
- Follow the app's instructions to initiate pairing and data transfer with your IQ-1204.
- The dive computer will display a confirmation message when data transfer is active.
Maintenance and Care
1. Cleaning
After each dive, rinse your IQ-1204 thoroughly with fresh water to remove salt, sand, and other debris. Dry with a soft cloth. Do not use chemical cleaners or solvents.
2. Storage
Store the dive computer in a cool, dry place away from direct sunlight and extreme temperatures. Ensure it is fully charged before long-term storage to maintain battery health.
