  })
  .then((newService) => {
    service = newService;
    return service.isLocked(); // Check if the beacon is locked.
  })
  .then((isLocked) => {
    if (isLocked) {
      return Promise.reject('The beacon is locked. Can\'t write new URL');
    }
    // Beacon's not locked. We can proceed with the recording of the new URL.
    // Keep in mind that the encoded URL must NOT be longer than 18 characters.
