When logged into BromCom go to Modules > Diary > Equipment Booking Requests.
Press New to add the equipment you would like to reserve.
Make sure you fill this Booking Request in enough, so the technicians know what equipment is going where for what time.
If there is a Recurrence for this booking you would like to do, press the Recurrence button.
Press Save and then it should then appear in the Equipment Booking Requests.
You will be able to see everyone else's bookings so you cannot clash bookings.
