Performance requirements in the electrical specifications are valid
over an ambient temperature range of +20° C to +30° C. The
Performance Requirement tolerances listed in the Electrical
Specification are doubled over the temperature range of 0° C to
+40° C, unless otherwise specified. Test equipment used to verify
Performance Requirements must be calibrated and working within
the limits specified in the service manual Equipment Required List.
Reference Information . Information that amplifies a performance
requirement or is of special importance is indicated by
