Shock
Listed are the levels of shock the product can withstand with No
damage being incurred. The values represent peak input acceleration
during an 2~3 ms half-sine shock pulse, 11 ms trapezoidal shock
pulse.
Non-Operating
MT:
35G's (Half-sine Shock)
35G's (Trapezoidal Shock)
SFF:
35G's (Half-sine Shock)
40G's (Trapezoidal Shock)
Vibration
Listed are the levels of vibration the product can withstand with No
damage being incurred. The values represent a flat random vibration
input acceleration profile across the given frequency range.

MT: Random Operating: ~0.21Grms (5-500
Hz) Swept Sine: 0.5g (5-500Hz) 5 min. dwell
at 4 resonance's 5Hz to 300Hz, (0.25G's
nominal).
SFF: Random vibration at
5Hz to 300Hz, (0.25G's nominal).
Non-Operating
MT: ~2.09Grms (5-500Hz), Non-Operational
SFF: Random vibration at 0.008G²/Hz,
10Hz to 500Hz, (2 Grms nominal).
Acoustic Noise
Listed are the declared A-WEIGHTED SOUND POWER LEVELS
(LWAd) and declared average desktop seated operator position A-
WEIGHTED SOUND PRESSURE LEVELS (LpAm) when the product is
operating in a 73.4°F (23°C) ambient environment. Noise emissions
were measured in accordance with ISO 7779 (ECMA 74) and declared
in accordance with ISO 9296 (ECMA 109).
