To use rooms and equipment in the calendar and block them in parallel to specific services, you must enter availability for them. These behave just like the work schedules for your employees.
Manually create availability ("work schedules") for rooms and equipment
After you have created your rooms and equipment, you can find them in the work schedule and assign availability to them.
Short video on maintaining availability for rooms and equipment:
Initially, only human employees are displayed in the work schedule. To display your rooms and equipment, first go to all employees and select the desired rooms and equipment.
You can then enter the availability in the same way as described in detail under Create work schedule.
How to link your services with the required rooms and equipment to avoid double bookings, you can find out here.
