To detach the unit (to change the battery, change the temperature unit, or reset the high and/or low alarm limits), grab it and pull until the two Velcro strips separate.

OPERATING INSTRUCTIONS DISPLAYING REAL-TIME TEMPERATURE To display the ambient temperature at the display unit, press the Ext/Int button until INT appears at button the right of the readout. To display the temperature sensed by the probe, press the Ext/Int until replaces INT.
SETTING HIGH AND LOW TEMPERATURE ALARMS Temperature alarms can only be set for the sensor in the external probe. You cannot set alarms with the display unit mounted on a wall or frame because setting alarm levels requires access to the °C /°F button on the back of the unit.
