Human Factors Aspects of the SB-3614 Switchboard

A study was made to assess, evaluate, and report human engineering, training, and logistical support implications associated with use of the SB-3614 automatic switchboard. Respondents noted many positive features of the SB-3614 switchboard, among them the following: Covers are light and strong, and provide convenient storage for ancillary equipment; Controls, markings, lighting, and fixtures are generally satisfactory, with specific exceptions; and Operation in automatic mode is easier and faster than for manual switchboards. The following are among the negative aspects reported: Storage of ancillary equipment is hampered by unsatisfactory retaining brackets; Design feature of separating converter from switchboard is inefficient; Certain routine maintenance and operating procedures are difficult or confusing to execute as a result of equipment design defects; Quality and types of selected signal lamps are unsatisfactory; and Power module generates annoying noise.
