Thank you for utilizing our online answer forums. We apologize that you are experiencing an issue with your remote control not working as expected. I would like to let you know most of the trouble shooting for the issue, is done physically at the Slingbox location. However there is a step we can try first that may yield in a working remote. I suggest going into the Slingbox settings on your Mac computer, and try and reconfigure your remote control. If you do this and are not able to get the remote working again. The Next thing is to have someone at the from the Slingbox location contact us, This is so we can assist them in getting your Slingbox 350 working properly again. Below is a link that will walk you through how to reconfigure your remote control as well as the contact information for our Voice and Chat Agents.
As promised here are those links:
Hope this helps
