I have a Uniden BC-1 and it appears to work fine the cb and weather station work. However when I push the button labeled "police" it no longer displays the "PO" on the display screen, instead "T1" appears on the display screen. I push the police button again and "T2" comes up on the screen. Is this machine trying tgo tell me something? I dont have the manual for it as I bought it used on ebay. Is there anybody familiar with the BC-1 that can give me any advice? Thanks!
