Awaken Sonde,

Activate Bluetooth

Once power is applied to the sonde, internally or externally, users can awaken their sondes from Sleep state using

any of several methods. Primarily, users activate EXO sondes and the Bluetooth connections via a magnetic

switch installed in sonde’s electronics compartment. e sonde will automatically disable the connection and

go to sleep once it has not received a Bluetooth signal for 5 minutes or a signal from the topside connector

for 30 seconds. In order to activate their sondes, users should keep a magnet with them when setting up and

deploying sondes. For more information on sonde states and LEDs, please see Section 2.4.

Handhelds and sensor tools contain embedded magnets
