TM 10-1670-305-23&P AUTOMATIC RIPCORD RELEASE, MODEL 451 0008 00 OPERATION UNDER USUAL CONDITIONS OPERATING PROCEDURES - CONT WARNING When the AR2 is used on the reserve parachute, the main parachute must be activated at an altitude high enough to obtain a fully deployed canopy at least 1,500 feet above the actuation altitude for the AR2. If the main parachute opens within only a few hundred feet of the AR2 actuation altitude, the AR2 may deploy the reserve parachute. The two parachutes may become entangled, which may result in death of parachutist. WARNING The JUMP/OFF switch must be set to OFF immediately after every jump. Setting the JUMP/OFF switch to OFF repositions the mechanism for the next jump and prevents inadvertent actuation on the ground or during transport. If the switch is left in JUMP position, the next jump will cause the AR2 to actuate prematurely. Two parachutes may deploy and become entangled, which may result in death of parachutist. 7. After completing the jump, move the JUMP/OFF switch to OFF. Verify that switch is in the detent position. 8. With the JUMP/OFF switch in the OFF position, prepare the AR2 for the next jump by repeating steps 1 through 4. 9.
