MTBF is defined for a particular interval, as the total operating time (time that the system is operating or capable of operating) of the population of Basic Handheld devices divided by the total number of failures (requiring corrective maintenance actions). MTBF can be calculated, but acceptance of stated values is based on an explanation of the methodology used and supporting data. Field data is preferred and, if available, should be provided as justification to any specified MTBF.

SL-70 System reliability shall support a high fleet Operational Availability

0.99 0.994 Operational Availability [AO] indicates the percentage of time that a system is operationally capable of performing an assigned mission and can be expressed as (uptime/ (uptime + downtime)). High fleet operational availability, given that the device requires no scheduled maintenance, is across the entire fleet including those devices unavailable because they are in maintenance or being shipped to and from the maintenance repair facility.

SL-71 System shall operate without scheduled maintenance.

Maintenance limited to battery replacement and external cleaning in the field without any special tools, procedures, or test equipment.
