Cant Hear CB Radio Thru Speakers

[Cimmeron]

Ok, just bought another 86 aspencade, i have a cb radio, not a aftermarket one, is one of the honda ones , turns on, no buttons stick, just when i turn it on, i hear nothing, now, my questen is this, do i need the headsets to hear it or should i be able to hear it threw the mounted speakers? is there a button im overlooking that would turn the radio off and turn the cb on? i hear the radio just fine. thanks in advance for any replies.
