(3) ERASE Switch. A push-button switch
placarded ERASE is used to erase all recordings after
a routine flight. The ERASE switch will only work
when the weight of the aircraft is on the landing gear.
To prevent accidental erasures, a time-delay circuit
makes it necessary to hold the ERASE switch pressed
for 2 seconds before the erasure process will begin.
(4) HEADSET Jack. A jack placarded
HEADSET 600 OHMS allows playback of all four
recording channels simultaneously.
