-40° C to +70° C* (-40° F to +158° F) *70° C operating temperature achieved with 0.85 meters/sec of airflow.

-40° C to + 55° C (-40° F to 131° F) The upper temperature safety limit of + 55° C, per Standard UL/IEC 60950-1, is less than the upper limit of +70° C for functional

operating temperature owing to the limitations on physical contact with product.

Vibration: Wakes the WVA from sleep mode; feature configured through the Power Management - Wake on Movement configuration settings.

Voltage: Wakes the WVA from sleep mode; feature onfigured through the Power Management - Wake on Alternator configuration settings.

Maximum range of +33V Performs several functions:

Resets the WVA to factory defaults: press and hold for ten seconds. Silences the buzzer/audible alarm; only applicable when the alarm is enabled through applications. Wakes the WVA from sleeping; must be configured through the WVA's Power Management configuration settings.

Buzzer/audible alarm Application-defined buzzer capability. The buzzer is controlled programmatically through the web services resource hw/buzzer.
