How to open a box

Before you fly within Tromso CTR, make sure your box is open.
To get the telephone number to the tower, please first join the Signal group "THPK flyboks" and ask there.
Before calling the tower and opening a box, make sure nobody else has opened it already otherwise it makes the club look uncoordinated. Please check the Signal group "THPK flyboks".
Once you open a box, post it on the Signal group "THPK flyboks" so that others know. Post which box, which altitude limit, until what time, and your contact.
Have your radio on set to 154.175 so that you can inform others about changes.
If you plan to close the box earlier, make sure nobody is in the air or about to launch and send other pilots 10-15 minutes warning.

Example conversation:

You: This is (your name) and I would like to fly paraglider in the box (name of the box) until 16:00 local time. Is this possible?

Tower: Yes this is possible, you can have the (name of the box) until 16:00 local time with altitude 2000 ft and below.

You: Confirming 2000 ft and below until 16:00. My contact number is (your telephone number).
