Via the pop-up window "IrDA connection" you can follow the status of your connection.

JTrak automatically compares transferred dives with the existing ones in the logbooks. If it already exists, the transferred dive is discarded.

The download time depends on the number of dives which are stored on the dive computer. Air integrated computers contain additional data, so the transfer time can take up to several minutes.

If the connection fails, a message window will pop up. In this case check the distance between the devices and try again.
