How do you use the Manual Release Tool (MRT)?

• A. Detach the MRT and hand it to a crew member for assistance
• B. Tap the MRT against the dispensing unit to release it
• C. Extend the needle of the MRT and insert into the pinhole opening at the dispensing unit, or use the curved end to pry the unit open
• D. Pull the trigger while swinging the MRT in a wide arc

Answer: (C)

The key idea is how the Manual Release Tool is designed to activate the dispensing unit. The MRT includes two built-in actions that directly engage the unit’s release mechanism: a needle-like extension to depress the internal release pin, and a curved end to pry the unit open if needed. Extend the needle and insert it into the small pinhole on the dispensing unit to push the release. If the pinhole isn’t accessible or the unit is stuck, use the curved end to apply leverage and open the unit, which allows the release to occur.

Other actions don’t trigger the release because they don’t interact with the mechanism in the way the MRT is designed—for example, simply handing it to someone, tapping it against the unit, or pulling a trigger and swinging it won’t actuate the release and could cause damage or injury. The correct method uses the tool’s intentional contact points (needle insertion or curved pry end) to reliably and safely release the dispensing unit.
