OPERATION OF YOUR NEW LASER/RADAR DETECTOR OPERATION OPERATION You are now ready to enjoy the convenience and security of your LRD 747/LRD 757. Please read this section of the Reference Guide carefully to familiarize yourself with the basic operation of this unit. POWER ON Turn the volume control to switch on the power. When you power up the LRD 747/LRD 757, it performs a self-test of all its circuits. This test takes about 5 seconds, during which you will hear the different alarm tones and see all the LEDs. First, you will hear the X-band alarm for 2 seconds while the X-band indicator lights. The test also checks the signal meter LEDs. It is best to adjust the audible alarm during the self-test. Next you'll hear the K-band alarm while the K-band indicator and City LED lights, Ka-SuperWideband alarm while the Ka-Band indicator and mute LED lights. The laser alarm and the SWS alarm will each alarm for 1 second, while the City and Mute LED light. The VG2 alarm will alarm for 2 seconds while the City and Mute LED light.(The power LED remains on until you turn off the unit.) When turned on the LRD 747/LRD 757 always returns to its last setting. After the LRD 747/LRD 757 confirms proper operation, the alert tones and all LEDs, except the green Power LED, turn off. If the Power LED does not light, check the cigarette lighter socket connection. If the unit turns on and off intermittently, or the alert tone sounds too often for no reason, check the power cord connection at both ends to be sure it is not loose. VOLUME CONTROL Adjust the volume control to a comfortable alarm tone level for your vehicle. The volume level does not have any effect on the unit's sensitivity. It is best to adjust the audible alarm during the self-test. 13
