13. DETECTION OF CELL PHONE USE With the multi-band, monopole antenna, the unit will detect and indicate RF signal(s) -60 dBm or higher In a building or outdoors within a radius of 50 feet, any cell phone will transmit at much higher signal level(s) (typically -30 dBm) For efficient coverage in all directions, the unit should be oriented vertically, with the monopole antenna pointing up or down Berkeley Varitronics Systems, Inc. - Liberty Corporate Park - 255 Liberty Street Metuchen, NJ 08840 - (732) 548-3737 - Clarifying RF -

14. LOCATING CELL PHONES‏ With the multi-band, directional antenna, the unit will identify Line of Position (LOP) for transmitting cell phones within a radius of 40-50 feet While sweeping the unit in the azimouthal directions, an LOP is identified when the “Sensitive” scale reads maximum level Berkeley Varitronics Systems, Inc. - Liberty Corporate Park - 255 Liberty Street Metuchen, NJ 08840 - (732) 548-3737 - Clarifying RF -
