Updating the Transmitter Software Using Your Descent Dive Computer

Before you can update the software, you must pair your Descent T1 transmitter with a Descent Mk2i dive
computer.
1 Select an option to sync your dive computer:
• Sync your dive computer with the Garmin Dive app.
• Connect the dive computer to your computer using the USB cable, and sync with the Garmin Express
application.
Garmin Dive and Garmin Express automatically look for software updates. When you sync with Garmin
Express, the update is applied immediately to your dive computer. When you sync with Garmin Dive, you will
be prompted to apply the update at a later time.
2 Install the transmitter on the first-stage regulator

select your transmitter.
5 Wait for the transmitter to connect to your dive computer.
Connected appears on the dive computer screen.
6 Select Software Update.
NOTE: This option may take up to a minute to appear while the dive computer determines the transmitter's
software version and battery status.
7 Verify the transmitter ID when prompted.
The transmitter ID is printed on the housing.
8 Keep the dive computer near the transmitter until the software update is complete.
