-40 °F to +185 °F (-40 °C to

+85 °C)

70% relative humidity (RH) –

40% moisture by volume

For 24 hours with a 12 V

supply

3.1.4 Storage Temperature

The Digi m10 can be stored for extended periods from -40 °F to +185 °F (-40 °C to +85 °C). It has

been subjected to the upper and lower temperature limits for 24 hours each and then checked for

stability.

3.1.5 Operational Shock

The Digi m10 remains structurally intact and operational after the drop test (as defined in

SAEJ1455) from 1.22 m onto each of its corners and its face.

The Digi m10 also meets the MIL-STD-810E, Method 516.4, Procedure I as defined in the

ORBCOMM Subscriber Communicator (SC) Standards and Specifications.

3.1.6 Operational Vibration

The Digi m10 meets the MIL-STD-810E, Method 514.4 and ETSI 300 721 as defined in the

ORBCOMM Subscriber Communicator (SC) Standards and Specifications.

In addition, the Digi m10 has also been tested according to SAEJ1455 (as per the practices for

heavy duty trucks), which specifies that the vibration profile for CAB-mounted vibration PSD for

Vertical Axis (Figure 6, 1.04 g rms) is to be tested in three mutually perpendicular planes and that

a sweep rate of ½ octave per minute is to be used.
