Pagination or Media Count:
The technical memorandum describes a series of inspections for cassette recorders that can be performed to assure that the devices are acceptable. The inspections can be completed in 20 minutes and can be performed by instructional personnel. The series of inspection procedures includes tests of the intelligibility of audio, physical condition, tape speed, impulse reliability, response range and torque delivered to the tape. It is suggested that acceptance testing could both avoid disruption of instruction and save money by obtaining repair or replacement under the warranty on the device.
