Code 4 means no other assistance is needed.
The security code "10-4 code 2" is a combination of two codes from the ten-codes used in radio communication. "10-4" typically means "acknowledged" or "received," while "code 2" often refers to a non-emergency response or situation that requires urgent attention but is not life-threatening. Together, it suggests that the message has been received and acknowledged, and the situation requires attention without the urgency of an emergency.
