with 65 Digital Voice Messages and Digital Display Operating instructions for model E936CS TM Ultimate Performance. Proven Technology. P R O T E C T I O N P R O T E C T I O N 360 ̊ Thank you for purchasing an EXPRESS 936 Radar/Laser/Safety detector. EXPRESS 936 offers the most advanced technology available for detecting all Radar and Laser speed monitoring devices. In addition, EXPRESS 936 features Digital Voice, Text Message Display and the Safety Warning System ® with 60 Digital Voice messages. To ensure maximum benefit from your new unit, please read all instructions before operating your unit. Remember, owning a Radar detector does not give you a license to speed. Alerts from a Radar detector serve as an effective reminder to check your speed. Laws vary throughout North America governing the use of a Radar detector. It is your responsibility to follow these laws. Safety Warning System ® (sws ™ ) EXPRESS 936 detects encoded signals from sws ™ transmitters and provides 60 messages for: Highway Construction/Maintenance, Highway Hazard Zones, Weather Related Hazards, Travel Information/Convenience and Emergency/Slow Moving Vehicles. For a complete description of sws ™ audio and visual alerts, see page 18. VG-2 Guard ® Alert EXPRESS 936 features VG-2 Guard ® , to detect signals from the Interceptor VG-2 (Radar Detector Detector). For a complete description of the VG-2 Guard ® audio/visual alert, see page 17. Safety Warning System ® with Digital Voice Messages Choose between Digital Voice Messages with a unique sws ™ tone or sws ™ tone only (see page 9). Radar/Laser Digital Voice Prompts Choose between Radar/Laser Digital Voice prompts followed by “beeps” or “beeps” only (see page 9).

REPORT:C0610-4 FCC ID:QL4G4M2 Page 3 of 8 Statement of Conformity 47 CFR 15.109(h) states that “Radar detectors shall comply with the emissions limits...of [section 15.109(a)] over the frequency range of 11.7 – 12.2GHz.” The applicable limit being 500μV/m measured at a distance of 3m. The following Beltronics M2 platform models have been tested and found to comply with this requirement: Express 916 Express 926 Express 936 822R REPORT:C0610-4 FCC ID:QL4G4M2 Page 4 of 8 Test Methodology Radiated emission testing was performed according to the procedures in ANSI C63.4 (2001). The testing was performed at an antenna to EUT distance of 1 meter. Performance was investigated in the range 11.7-12.2GHz. The Express models were powered by a R.O.C. SPN4025A 12VDC 400mA power supply, and the 822R was powered by a HP E3612A DC Power Supply. Since the devices are hand-held units, the emissions were maximized around the three orthogonal axes and the maximum reading was recorded. The integrated antenna cannot be maximized separately.
