Controls and Features Audible Alerts For Radar signals: The STi-R uses a geiger-counter-like sound to indicate the signal strength and type of radar signal being encountered. When you encounter radar, a distinct audible alert will sound and occur faster as the signal gets stronger. This allows you to judge the distance from the signal source without taking your eyes from the road. X-band = chirping K-band = buzzing Ka-band = double-chirp Laser = rapid fire chirping SWS = double buzz POP = full double-chirp For Laser signals: Since laser signals are a possible threat no matter how weak, the STi-R alerts you to these bands at full signal strength. For Safety signals: The STi-R will alert you to these signals with a double-beep tone, and a corresponding text message. A complete listing of the text messages is on page 21. Signal Strength Meter The STi-R's alphanumeric display consists of 280 individual LEDs, to provide an intuitive ultra-bright display of signal strength and text messages. The STi-R's standard bar-graph signal strength meter displays band identification on a single radar signal. If there are multiple signals present, STi-R's internal computer determines which is the most important threat to show on the bar-graph meter. When STi detects radar, it displays the band (X, K, Ka), and a precise bar-graph of the signal strength. When the STi-R detects a laser signal, the display will show "LASER." When it detects a POP signal, the display will show "POP." NOTE: If you are operating the STi-R in the Dark mode, the display will not display anything when a signal is detected. Only the audio will be heard. For POP signals: Since POP signals are extremely fast K or Ka bursts, and a possible threat no matter how weak, the STi-R alerts you to these bands at full signal strength. 8 Threat Display Your STi-R's Threat Display option is an advanced display for experienced detector users. Please use the STi-R for a few weeks to get familiar with its other features before using Threat Display. To use the Threat Display instead of the bar graph signal strength meter, you must select Threat Display in the STi-R's Programming (see pages 10-14). The STi-R's Threat Display simultaneously tracks multiple radar signals and their relative signal strength. Threat Display can help you spot a change in your normal driving environment; for example, a traffic radar unit being operated in an area where there are normally other signals present. The Threat Display is actually a miniature spectrum analyzer. It shows what band each signal is and its signal strength. Ka9 K2 X1 Above is the Threat Display if the STi-R was detecting a strong Ka-band, a weak K-band, and a weak X-band signal. A few more examples will help you better see how the Threat Display works. K9 X1 Here Threat Display shows a strong K-band signal, and a weak X-band signal. Ka1 X9 Here Threat Display shows a weak Ka-band signal, and a strong X-band signal. Threat Display Details The band designators (X, K, Ka) will stay on the display for a few seconds after the signal has passed. This allows you to see what the unit detected, even on very brief signals. Tech Display The STi-R's Tech Display option is for the experienced detector user. In this mode, the STi-R will display the actual numeric frequency of the radar signal being received. K 24.150 Tech Display shows one K-band signal at 24.150 gigahertz. Even long-time detector users will require a significant amount of time to get familiar with this new level of information about detected signals. 9
