Claim Text:
1. A method, comprising: receiving, in response to an actuator of a medicament delivery device moving relative to a housing of the medicament delivery device, a first electronic signal, the medicament delivery device configured to move a needle from a retracted position within the housing to a delivery position outside of the housing and to deliver a medicament via the needle in response to the actuator activating an energy storage member, the actuator activating the energy storage member when the actuator is moved in a first direction from a first actuator position to a second actuator position; sending, in response to receiving the first electronic signal, a second electronic signal to a speaker to cause the speaker to emit an audible instruction associated with a use of the medicament delivery device; engaging a lock portion of the actuator with a corresponding portion of the housing to limit movement of the actuator from the second actuator position towards the first actuator position after activation of the energy storage member; and moving, independent from movement of the housing and after the delivery of the medicament via the needle, the needle in a proximal direction from the delivery position outside of the housing towards the retracted position within the housing.
