(b) be readily accessible for immediate use from each required flight crew station;

(c) have, for each floor level passenger [emergency exit](https://avioverse.aero/glossary/easa/emergency-exit) that has an adjacent cabin crew seat, a microphone operable by the seated [cabin crew member](https://avioverse.aero/glossary/easa/cabin-crew-member), except that one microphone may serve more than one exit, provided the proximity of exits allows unassisted verbal communication between seated cabin crew members;
