Step 3: Configure RC-308
To configure RC-308 buttons via K-Config:
Configure RC-308 (go to www.kramerav.com/product/K-Config).
Connect RC-308 to a PC via the Ethernet or connect via the mini USB port.
Sync the configuration to the RC-308.
To insert a button label:
When inserting a button label for the first time, start from #3 below. When replacing a button label, start from #1 below.
1. Using the supplied tweezers, grip the button via the left and right ledges.
2. Remove the button cap.
3. Cut out the appropriate button labels from the button label sheets and place a label over the button.
4. Cover with the button cap in the correct direction (with ledges left to right).
You do not have to detach the faceplate to remove a button.

Step 4: Connect the inputs and outputs
Always switch OFF the power on each device before connecting it to your RC-308. For best results, we recommend that you always
use Kramer high-performance cables to connect AV equipment to RC-308.
Step 5: Install RC-308
After connecting the ports, insert the device into the in-wall box and connect the parts as shown in the illustrations below:
European Version
US Version
We recommend that you use any of the following standard 1 Gang in-wall junction boxes:
US: 1 Gang US electrical junction boxes.
EU: 1 Gang in-wall junction box, 47mm minimum depth (DIN 49073).
UK: 1 Gang in-wall junction box, 75x75mm, 47mm depth (BS 4662).

Step 6: Connect the power
If the device is not powered via PoE, connect the 12V DC power adapter to the RC-308 and plug the adapter into the mains.
