PRO-50 (200-0307) Preparation Faxback Doc. # 6902 RESETTING/INITIALIZING THE SCANNER If the scanner's display locks up or does not work properly after you install new batteries or after you connect an external power source, you might have to reset the scanner. To reset the scanner: 1. Turn on the scanner. 2. Press the reset switch at right of the PWR jack using a pointed object, such as a straightened paper clip. If this is not effective, initialize the scanner as directed below. Caution: Use this procedure only when you are sure the scanner is not working properly. This procedure clears all information you have programmed into the scanner. To initialize the scanner: 1. Turn on the scanner. 2. Press and hold CLEAR and then press the reset switch at the right of the PWR jack using a pointed object, such as a straightened paper clip. Release CLEAR after the display reappears. CONNECTING THE ANTENNA Follow these steps to attach the flexible antenna to the ANT (antenna) jack on the top of the scanner. 1. Slip the slot in the antenna's connector over the protrusions on the jack. 2. Press down and rotate the base of the antenna until the antenna locks into place. Connecting an Optional Antenna The antenna jack on your scanner makes it easy to use your scanner with a variety of antennas. You can remove the supplied antenna and attach a different one, such as external mobile antenna, telescoping antenna, or outdoor base antenna. Use coaxial cable to connect an outdoor antenna. Always use 52-ohm coaxial cable, such as RG-58 or RG-8. For lengths over 50 feet, use RG-8 low-loss coaxial cable. Radio Shack stores sell the antenna connector adapters that let you use these antennas. (smm/all-7/14/94)
