If the logger is currently logging at a fast interval (5
seconds or faster) and the temperature is -10°C (14°F) or
below, you may need to press the button twice before it
appears in the list.

Make sure the logger is within range of your mobile
device. The range for successful wireless communication
in air is approximately 30.5 m (100 ft) with full line-of-
sight.
•
Change the orientation of your phone or tablet to ensure
the antenna in your device is pointed toward the logger.
Obstacles between the antenna in the device and the
logger may result in intermittent connections.
•
If your device can connect to the logger intermittently or
loses its connection, move closer to the logger, within
sight if possible. If the logger is in water, the connection
can be unreliable. Remove it from water for a consistent
connection.
•
If the logger appears in the app, but you cannot connect
to it, close the app and power cycle the mobile device.
This forces the previous Bluetooth connection to close.
Once the logger is connected, you can:

readout will be completed automatically at the
beginning of the firmware update process
Important:
Before updating the firmware on
the logger, check the remaining battery level

sure you have the time to complete the
entire update process, which requires that
the logger remains connected to the device
during the upgrade.
