UNIDEN LONG RANGE RADAR/LASER DETECTOR USER’S MANUAL R4 R4 OVERVIEW Uniden’s R4 is a top of the line Radar Detector with a built-in GPS feature. With the R4, you can mark geographical points where you commonly encounter radar transmissions. These can be school zones, red-light cameras, and places where police frequently monitor traffic. You can mark these points so the detector will announce “User mark ahead” when you approach them.

ELEMENT USB Port WHAT IT DOES... Use this USB port to charge mobile devices. OLED DISPLAY The OLED display on the front of the unit changes depending on what events are happening. If GPS = ON, the OLED’s left display area shows the display selected in the menus (see page 21). If GPS = Off, the OLED’s left display area shows Volt regardless of user settings. The following table provides examples of the most common OLED displays.
OLED EXAMPLES MEANING User Mark Detected Information displayed: • Current speed in mph/km/h • Distance to user mark • User mark icon 58 620 ft mph Time Display (Scan Display Off) 58 mph P M 11:45 H Quiet Ride Display Display Style #1 45 mph K 24.
1. 2. 3. 4. Attach the rubber suction cups to the bracket and push the cups firmly onto the windshield. Slide the unit onto the bracket until it clicks into place. Plug the power cord RJ11 connector into the R4 and plug the cigarette lighter adapter into the vehicle’s cigarette lighter. When the vehicle turns on, the R4 automatically turns on and runs through a self test cycle. Release the R4 from the bracket by pressing the Eject key on top of the detector.
In addition, GPS can be turned on and off only through the Expert menus. GPS status also affects which menus may display in the Basic or Expert levels. For example, if GPS is turned on, then the Speed Camera Alarm menus display. If it is not turned on, then those menus will not display. If a menu depends on Level, Mode, GPS , or a different status, that dependency will be noted in the specific menu entry itself. The following table lists all the menu options from all levels and modes.

Example 1: 12.8 Ka 12.8 Ka V 33.800 Example 2: V 33.650 GATSO RT3/RT4 FREQUENCY RANGES There are two types of Gatso traffic enforcement systems - RT3 and RT4. RT3’s frequency range is 50MHz and RT4’s is 100MHz. The following example shows the alert for Gatso RT4 in display format #2. 39 mph RT4 Gatso MODES (HIGHWAY, CITY, AUTO, AND ADVANCED) Uniden’s R4 radar detector operates in two different frequency (X, K, and Ka band) sensitivity modes - Highway and City.

POP MODE In POP mode, the R4 can detect short burst from radars that are too fast for many other detectors to catch. You can turn POP mode on and off in the Expert menus. QUIET RIDE (GPS On) This function mutes X and K band radar alarms when you drive under a speed limit set in this menu (up to 90 mph/140 km/h).
THREATS The R4 detects up to 4 radar band signals (threats) at a single time. The strongest rader signal is designated as the Priority signal, and its frequency displays on the OLED. The other 3 signals (threats) are indicated in the left side of the display. In the following example, 3 K bands and 1 X bandfrequencies are detected. X K K K 24.158 GHz The Priority menu setting determines which type of frequency displays on the OLED (see page 18).
