When your Logger is showing 'not rdy' (not ready) or 'slp' (sleep) on the display, your Logger has been hibernated to preserve its battery before the logger is used.

To remove the logger from hibernate state it must be configured with LogTag Analyzer software.

On the TRID/TRED model loggers, you can press and hold the 2 buttons for 6 seconds. During this time the text “READY” flashes. Release the buttons when the flashing stops. This will re-activate the Logger and get it out of the hibernation state. 

You can re-activate a Logger with a low battery, however it is not recommended to commence another trip.

Note: The real-time clock is not running in a hibernated recorder and must be set up if the recorder is manually activated.
