While listening to a channel, adjust the SQUELCH knob until the noise is filtered and you can hear only the transmission. If you switch to a channel with a lot of noise or a weak trans- mission, you may need to readjust the squelch level again.
Note: Setting the squelch level too high may prevent you from hearing weaker transmissions. If you are having difficulty hearing a transmission, try setting the squelch level lower.
