While listening to a channel, adjust the SQUELCH knob until the noise is filtered out and you can only hear the transmission. If you switch to a channel with a lot of noise or with a weak transmission, you may need to adjust 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. Changing the Channel Press CHANNEL UP and CHANNEL DOWN briefly to scroll through the channels one channel at a time. Press and hold CHANNEL UP or CHANNEL DOWN to quickly scroll through the channels. Making a Transmission To make a transmission, press and hold the microphone PUSH TO TALK button. Release the PUSH TO TALK button when you're finished talking to let the other party respond. xx To prevent stuck microphone problems or situations where PUSH TO TALK is pushed accidentally, the radio limits your talk time to 5 minutes in a single transmission. If you talk for over 5 minutes continuously, the display shows RELEASE MIC BUTTON. xx For the best sound quality, hold the microphone about two inches away from your mouth. xx You cannot transmit while the radio is in weather mode or scan mode. xx See the channel lists beginning on page 37 for a list of receive-only channels. Boosting the Transmission Power In most situations, the 1 Watt transmission power is all you need. If you find yourself far away from other stations and have trouble getting a response, you may need to boost the transmission power from 1 Watt to 25 Watts: 1. Select the channel you want to transmit on. 2. Push and hold ENT-1W/25W for two seconds. The display shows 25 Watts in the upper left hand corner. 3. The transmit power remains at 25 Watts until you change the setting back. Push and hold ENT-1W/25W for two seconds. The display shows 1 Watt. ## NOTE: Don't forget to change the transmission setting back to 1 Watt when you move closer to other stations. ## NOTE: By default, when you change to channel 16, the radio automatically boosts the power to 25 Watts. Be sure to change the power back to 1 Watt if you are not making an emergency transmission. 12
