Introduction IYnoutrrBoCd2u4c6tTioscnanner is a state-of-the-art scanner radio with TrunkTracking™ and automatic scanning capabilities. You can store frequencies such as police, fire/emergency, marine, air, amateur, and other communications into the scanner. You can carry it with you wherever you go, use it at home as a base unit, or install it in your vehicle as a mobile unit. You can use the scanner's scroll control to quickly select channels and frequencies, and you can automatically program channels in a system using the AutoStore feature. Use your scanner to monitor: • Trunked public safety systems • Police and fire departments (including rescue and paramedics) • NOAA weather transmissions • Business/Industrial radio • Utilities • Marine and amateur (ham radio) bands • Air band • Railroad This table lists the frequency ranges, default frequency step, default mode (AM or Narrowband FM), and type of transmissions you can hear for each range.
