Each chapter of the digital guide matches one stop on the route.
When your guide stops to describe a space, open the matching section and listen to the audio or read through the content.
When the explanation is over and the group moves on, you can go to the next chapter. Only start it once your guide has stopped at the new point.
That way the content on your phone follows the visit step by step.
The route runs through underground spaces, stairs and uneven ground.
Look at your phone while the group is standing still, and always watch where you are walking when it moves on.
So as not to disturb your guide’s explanation or the other visitors, the audio tracks may only be listened to with earphones.
Do make sure they are connected to your phone before the visit begins.
If you would rather read, the AA symbol at the top right lets you choose between three text sizes.
If you downloaded the content on the previous screen, the audio, text, images and maps are already on your device and will keep working with no network at all.
