In the event of power failure while the system is on line , the buffer arms will extend and tension on the tape will be relaxed, preventing any possible tape damage.
When power has been restored, tape system operations may be resumed by first taking up the tape slack and then pressing the LOAD pushbutton.
Lead the end of the tape over the buffer arm guide and down through the slot guide in the head assembly cover.
The passage of the tape through the slot causes the small shield over the head assembly to move away from the head.
It is accessible only when the tape unit is swung open for service.
