Hi Capt MAC,
"At the direction" means the PF calls for the appropriate check list e.g. "Fire Engine Check List".
In my previous company, the PM then repeated "Fire Engine Check List" to confirm they understood the correct procedure. Then it was done from memory by the PM calling each action with the PF monitoring and confirming the correct vital actions. When the memory items had been completed, then the QRH was read and cross checked that nothing had been missed.
