You mix it up by programming the chirp and a random panicked message from your crew that:

• a Klingon ship has decloaked
• the Cardassians are contacting us
• a Borg ship has been detected
• we’ve lost main ship power and we are on emergency power only
• the ships gravity assist is malfunctioning
• we’ve detected a space-time rift in your area
• a Gorn colony has been detected in your area
