I need help with my CB radio [Going on a long trip to canada Please help!]

Ok, so my friend recently gave me this Radio here, i ordered on ebay a power plug the other day, and i already have the antenna and mic, Once i got the new plug, (I never used it before) The device did turn on, i made sure everything worked, channels, buttons, etc. How ever, When i tried to radio check. I got nothing. I didnt even hear static, I got my handheld CB and did the same channel. Nothing. How ever, when i click the mic, i hear that distinct *clink* sound and less static on my handheld, Nothing on the cb. The red lights worked, everything. Even the Night time ones for the switches, Here is a photo of the radio, Please someone i rlly Need help with this thing :c Im going on a trip from NJ to Ottawa Soon and i need to make sure i dont get bored as i am going on my own up their with my Boyfriend whos already up their,
