      How do I use the Trek Tab?

      The Parsyl Trek tab is a single-use wireless data logger that monitors temperature, and can be activated for placement in shipments using these directions.

      Turn on the Trek Tab

      1. Press and hold the center Push button for four seconds until the centerLED blinks green.

      2. The Trek Tab is now activated and monitoring.

      Checking the Status

      If you are unsure if the Trek Tab is activated, quickly press and release the center PUSH button. Do not hold it.

      • If no LEDs light up, the device is not activated.
      • If the center LED blinks green, the device is activated.
      • If the two side LEDs light up, the device has already been used. Don't use it.
