Press `Ctrl` + `Enter` (`⌘` + `Enter` on Mac) to jump into the server you used last. The CAD server list with a few server cards, one marked Last visited, and the Join Server door button below A server shows up when it has the CAD enabled and you have at least one CAD permission there, either from a department rank or a join code. Not seeing your server? Ask your admins for a join code. *** ## Choosing a Panel After picking a server, click a panel tile to open it. Scroll sideways if you have a lot of panels. * A greyed-out tile means the server has no department for it yet, or you don't have permission. Hover it to see which. See [Panel Access](/CAD/Intro/permissions#panel-access). * Dispatch and service panel tiles have a small radio icon that opens a radio-only page. See [Radio](/CAD/User/radio). * The **Admin** button at the bottom opens the admin panel, if you have CAD Admin. You can only be active on one panel at a time. If the panel is open in another tab, you'll be asked which one to keep. *** ## Joining with a Code Join codes let people outside your departments use the CAD. Joining gives you a temporary membership with the permissions on that code. On the server list, click the **Join Server** door button. Fill in the Community Code (your server's code) and the Join Code your admins gave you. Click **Join**. You'll go straight to the server's panel picker. The Enter Join Code window with Community Code and Join Code fields and the Close and Join buttons If your admins sent a join link, opening it fills in both codes for you. Already in a server's CAD and given another code? Click **Enter Permission Code** on its panel picker. The new permissions are added to the ones you have. * Codes can't give CAD Admin, DMV Panel or radio moderation permissions. * A code can expire a set number of days after you join. You lose its permissions when it does. * Some codes need you to have certain Discord roles in the server's linked Discord. * A CAD admin can remove your membership or block you from joining with codes. Anything your department ranks give you stays. See [Members](/CAD/Admin/members#members-joined-by-code) for the admin side. *** ## Creating Your Unit On Police, Fire, EMS, DOT and Dispatch, you need a unit before you can do anything. Click **Create Unit**, enter your unit number and agency, then select it. See [Units](/CAD/User/units). On the Civilian panel you pick or create a character instead. On the Law panel you set your judicial name. DMV doesn't need either. ### Roblox authorization On Police, Fire, EMS, DOT and Law, link your Roblox account by clicking **Authorize Roblox** when asked. The panel works without it, but you won't appear on the live map. *** ## Clocking In You can start and end department shifts without leaving the CAD. Open the CAD menu (the logo in the top-left) and go to **Activity**. The CAD menu with the Activity submenu open, showing the Clocked out header and a department with Start shift and shift type options * Pick a department to start a shift, or pick a shift type if it uses them. * While on shift, you can start or end a break, or end your shift. If the department has a shift report form, it opens when you end. * Shifts work just like the department's Activity page, including Discord roles and shift logs. See [Department Activity](/Department/activity/shifts#shift-types). Activity only appears if you're in a department of this panel's type. A shift you started from the CAD ends automatically when you leave the panel, log out of your unit, or lose connection. ### When clock-in is required If your server turns on Require Clock-In, you must be on shift before you can become a unit or run lookups. If your shift ends, you're removed from the panel. This doesn't apply to Civilian, Law, DMV or CAD admins. *** ## Bodycam If your server turns on Require Bodycam, you must start your bodycam before you can become a unit on Police, Fire, EMS or DOT. See [Bodycam](/CAD/Intro/interface#bodycam) for how to start it. *** ## Connection Problems If you see Connection Failed, click **Try Again**. If you're told you've been removed or disconnected, it's usually because you opened the CAD in another tab or device, an admin kicked you, or your required shift ended. *** ## Desktop and Mobile The CAD also runs in the [desktop app](/CAD/Intro/interface#desktop-app), which adds global keybinds and pop-out windows, and on [phones and tablets](/CAD/Intro/interface#mobile) in landscape. *** Still have questions?
