Adjust the VOICE LOCK control to clarify the SSB signals or to optimize AM signals. Turn the SQUELCH control slowly clockwise, until the noise JUST disappears. Do not advance the control too far, or some of the weaker signals will not be heard. If the channel is clear, press the push-to-talk switch on the microphone and speak in a normal voice. The S-RF meter will indicate relative power output and the modulation meter will indicate percentage of modulation as you speak into the microphone. CAUTION Be sure the antenna is properly connected to the radio before transmitting. Prolonged transmitting without an antenna or a poorly matched antenna could cause damage to the transmitter. Turn the Weather Channel Selector (1-7) until you find the Weather Channel with the clearest reception. Sometimes more than one channel can be received depending on your location in the broadcast area; however, the closest broadcast to you will be the one with the clearest signal (the least static or background noise). 10 Section IV Operation (Continued) OPERATING PROCEDURE TO RECEIVE WEATHER BAND continued 3. If threatening weather is nearby, the National Weather Service may broadcast a 10 second alert tone. This tone will be heard through the CB, even if the WX/CB Switch is in the CB mode or the unit is turned off (see NOTE below). This enables you to monitor CB frequencies and still be warned by the National Weather Service Emergency Alert. NOTE: If you are using the CB Mode, remember to change the WX/CB Switch from CB to WX every so often to make sure you are continually tuned to the clearest weather band channel in case an alert is broadcast. For proper procedure to set your LCD Clock, there are the following features: TIME SET: 2 switches (used to set time). CTR. /CLOCK: On power up, the display shows channel number and frequency being received. When switching out of WX mode, the display will continue to show the clock until the FREQ. 12:00 midnight Cobra RX ® 2010 GTL WX HOUR LSB : MIN FREQ. CTR. CLOCK 11 Display in RX mode with Clock showing. Section IV Operation (Continued) RECEIVING SSB SIGNALS There are three types of signals presently used for communications in the Citizens Band: AM, USB, and LSB. When the MODE switch on your unit is placed in the AM position, only standard double-sideband, full carrier signals will be detected. An SSB signal may be recognized while in the AM mode by its characteristic "Donald Duck" sound and the inability of the AM detector to produce an intelligible output. The USB and LSB modes will detect upper sideband and lower sideband respectively, and standard AM signals.
