3.3.10.4
3.3. 10.5
Temperature - The equipment shall operate as specified herein
from -25C to and including +55C. The equipment shall also operate as specified for tests above
+55C per MIL-T-5422 except for the Drum Auxiliary Memory Subunit (DAMS) of Logic Unit 4 which
shall not be required to meet the DAMS error rate requirements. However, no damage or degrada-
tion shall occur to the DAMS during high temperature MIL-T-5422 tests. From below -25C to -54C
the equipment shall not be required to meet specification performance requirements; however, no
damage or degradation shall occur to the equipment within the -25C to -54C limits.
Altitude - The equipment shall operate satisfactorily up to a
3.3.10.6
maximum altitude of 15,000 feet.
Warm-Up Time - The time required for the equipment to warm
3.3.11
up prior to operation shall be kept to a minimum and shall not exceed 0.5 minutes from 0 to and in-
eluding +55C and 5 minutes from less than 0C to and including -25 `C.

3.3.12
Primary Input Power Requirements - The equipment shall meet
3.3.12.1
all applicable requirements of MIL-STD-704 and shall give specified performance from the following
power sources with characteristics as defined in MIL-STD-704 having limits as modified herein. The
equipment shall operate within the bounds of limits 2 and 3 of Figure 3 of MIL-STD-704 except that the
lower limit of curve 3 shall not fall below 80 volts. Operational malfunction may occur when the input
voltage exceeds the above limits but remains within limits 1 and 4 of Figure 3 of MIL-STD-704. How-
ever, no damage shall be suffered by the equipment under transient conditions defined herein. Normal
operation shall autoctmatically be resumed upon return of the input voltage to levels within limits 2 and 3
as modified herein. The power required shall not exceed the following specified amounts.
