UNIDEN UHF CB Transceiver Operation Setting the Squelch 1. To turn the unit ON, rotate volume clockwise. Adjust volume to a comfortable level. You must select a channel which is not in use before setting the SQUELCH control.(see p.10) 2. Think of the Squelch control as a gate. If you turn SQUELCH fully clockwise it raises the "Squelch Gate so that no signals get through. 3. If you turn the SQUELCH fully counter clockwise, it lowers the "Squelch Gate" so that everything gets through - noise, weak
