NOTE: You will notice an “A” indicator adjacent to some channel numbers in the USA and Canadian bands. These are simplex channels (transmitting and receiving on the same frequency) while the International counterpart is a duplex channel (transmitting on one frequency while receiving on another.)

Setting the Squelch Threshold
Setting the Squelch is important for reception of signals you want to hear. There are ten threshold levels, from 0, which allows all signals to be received, to 9, which allows only the strongest signal to be heard through the speaker. The diagram in Figure 5 demonstrates how setting the threshold level allows you to hear only the signals you desire, while weaker, unintelligible signals are not heard.
To set the Squelch threshold:
1.Adjust the Squelch to the lowest setting by pressing and holding the Squelch (SQ) key, then pressing the DOWN arrow key repeatedly until the display indicates “L0”. You should hear static. If you hear a voice transmission, change to another channel and repeat this step. (Figure 5)
2.While holding the Squelch (SQ) key down, use the UP arrow key to increase the squelch level to “L1”. If no static is heard, you have set an acceptable squelch threshold level. If you hear static, then increase to the next threshold level, repeating the process until unwanted static is eliminated. Release the SQ key to return to your selected channel. The squelch setting is universal for all channels, but it may require resetting from time to time
NOTE: During squelch adjustment,
