  • Page 8: Scanning Legally

    accept any interference received, including interference that may cause undesired operation. SCANNING LEGALLY Your scanner covers frequencies used by many different groups, including police and fire departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wireline (telephone and telegraph) service providers.
  • Page 9 components or using it in a way other than as described in this manual could invalidate your warranty and void your FCC authorization to operate it. In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area. It is also illegal in many areas (and a bad idea everywhere) to interfere with the duties of public safety officials by traveling to the scene of an incident without authorization.

  • Page 10: Introduction

    INTRODUCTION Thank you for purchasing a Uniden SR30C handheld scanner. The scanner is versatile, compact, and easy to use. In addition to its standard scanning features, your scanner also includes Close Call® RF capture technology designed to help you detect and identify strong local radio signals in your area.
  • Page 11 PC Programming - lets you program your scanner using your PC. Custom Search - lets you program up to 10 custom search ranges and search any or all of those ranges. Quick Search - allows you to enter a frequency and start searching up or down from that frequency.
  • Page 12 Priority Scan with Do Not Disturb - lets you set the Priority feature to check each channel every 2 seconds as long as the scanner is not receiving transmissions. Duplicate Channel Alert - lets you know when you have entered a frequency that is already registered on another channel.

  • Page 17: Scanning Basics

    Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. Your SR30C scans programmed channels until it finds an active frequency, then stops on that frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until it receives another transmission on a programmed channel.

  • Page 18: Conventional Scanning

    Conventional Scanning Conventional scanning is a relatively simple concept. Each group of users in a conventional system is assigned a single frequency (for simplex systems) or two frequencies (for repeater systems). Any time one of them transmits, their transmission always goes out on the same frequency. Up until the late 1980’s this was the primary way that radio systems operated.

  • Page 19: Repeater Operation

    Repeater Operation Repeater systems use two frequencies: one transmits from the radio to a central repeater; the other transmits from the repeater to other radios in the system. With a repeater-based system, the repeater is located on top of a tall building or on a radio tower that provides great visibility to the area of operation.

  • Page 20: Custom Search Ranges

    these service searches just like the channel storage banks, searching the frequencies using Service Search mode (see page 37). Custom Search Ranges Custom Search mode lets you program the upper and lower limits of search ranges. You can then search these 10 custom search ranges starting from the lowest frequency to the highest frequency in the search range you entered.

Slide the antenna’s connector down over the scanner’s connector. Rotate the antenna connector’s outer ring clockwise until it locks into place. The scanner’s BNC connector makes it easy to connect a variety of optional antennas, including an external mobile antenna or outdoor base station antenna.

  • Page 23: Connect An Optional Earphone/Headphone

    Connect an Optional Earphone/Headphone For private listening, you can plug a 1/8-inch (3.5 mm) mini- plug earphone or stereo headphones (not supplied) into the headphone jack on top of your scanner. This automatically disconnects the internal speaker. Connecting an Optional Extension Speaker In a noisy area, an optional extension speaker, positioned in the right place, might provide more comfortable listening.

    Inside the battery compartment is a switch; set the unit to either ALK or Ni-MH to match the type of battery you’re using. WARNING! Non-rechargeable batteries can get hot or burst if you try to charge them. CAUTIONS: • When flashes in the display and the scanner beeps every 15 seconds, recharge or replace the batteries .

If the scanner judges the batteries are good, the scanner starts charging and the battery icon disappears. If it cannot regard the batteries as good in 60 seconds, the scanner stops checking and the battery icon blinks.

  • Page 28: Adjust Squelch

    Adjust Squelch The scanner recognizes signals as transmissions if they exceed a signal strength threshold. Adjusting the squelch sets this threshold level. Increasing squelch requires a signal to be stronger to be seen as a transmission. If you set the squelch too high, you will risk not receiving transmissions that are lower than that threshold.
