My transmitter battery is draining rapidly

If your transmitter battery is draining faster than the expected battery life
you should make sure the transmitter is returning to low power mode after a dive.
When you return to the surface after a dive, depressurize your regulator.
The installed transmitter enters low power mode after two minutes have elapsed.

My transmitter makes an audible noise while diving

The transmitter makes an audible noise when transmitting data over the Subwave
normal operation. Sonar signals are noticeable while diving, and because sound travels better through water
than radio waves, the Subwave sonar network has longer range than traditional radio-based products. The
Subwave sonar network uses a lower power signal (1 W to 10 W) than traditional marine sonar systems
(around 1000 W). Testing has not indicated any disturbance to sea life.
You can decrease the power setting to reduce the audible noise from the transmitter
Power Setting, page 134).

Acquiring Satellite Signals

The device may need a clear view of the sky to acquire satellite signals. The time and date are set automatically
based on the GPS position.
TIP: For more information about GPS, go to www.garmin.com/aboutGPS.
1 Go outdoors to an open area.
The front of the device should be oriented toward the sky.
2 Wait while the device locates satellites.
It may take 30–60 seconds to locate satellite signals.

Improving GPS Satellite Reception

• Frequently sync the device to your Garmin account:
◦ Connect your device to a computer using the USB cable and the Garmin Express application.
◦ Sync your device to the Garmin Dive app using your Bluetooth enabled smartphone.
◦ Connect your device to your Garmin account using a Wi‑Fi wireless network.
While connected to your Garmin account, the device downloads several days of satellite data, allowing it to
quickly locate satellite signals.
• Take your device outside to an open area away from tall buildings and trees.
• Remain stationary for a few minutes.

The temperature reading is not accurate

Your body temperature affects the temperature reading for the internal temperature sensor. To get the most
accurate temperature reading, you should remove the watch from your wrist and wait 20 to 30 minutes.
You can also use an optional tempe external temperature sensor to view accurate ambient temperature
readings while wearing the watch.
