B737 Landing checklist question

[akafrank07]

Pilot Flying - At glide slope “alive” call “GEAR DOWN”, “FLAPS 15”. Arm speed brake and check green light illuminated. Call “LANDING CHECKLIST DOWN TO FLAPS

Pilot Monitoring - Position landing gear lever DN, FLAP lever to the Flap 15 detent. POSITION Engine Start Switches to CONT. Check RECALL

What does position engine start switches to CONT mean and check RECALL?

"The go-around must be initiated by DA. Therefore, at the minimums call, it is important that the pilot flying, without delay, accomplishes the Go-around. It is not necessary for the pilot flying to search for visual cues at this point. The pilot monitoring shall call the visual cues as they become apparent. If the pilot flying has not heard any visual cue calls from the pilot monitoring, it is save to assume that no visual cues have been received.Execute a Go-around."


In this context above is the 'minimums call' referring to DA?


Thanks
