Glossary Indicate: - RX receiver placed inside the NBC board (radiofrequency 433.92 MHz) - F 0 working frequency (433.92 MHz) - V B battery voltage - T AMB room temperature Sistemi Elettronici Viale Aldo BORLETTI 61/63 I-20011CORBETTA - MI Tel +39-02.9722.1 Document No.: 09/2004 Page 3/6 Version 01 Date: 04-09-20 GENERAL DESCRIPTION Generality The component RADIO CONTROL TRF 937/010 in “key head” consists of the following parts: N°1 base plate N°2 plastic semi-shell (key body) N°1 lithium battery CR 2032 (3V 180 mAh) The information provided in this document relates to the RADIO CONTROL RF. For the remaining subjects (Overhead receiver RF) refer to the specific product description. The purpose of the device is to carry out the functions of TRANSMISSION of the encrypted variable code to the RF receiver placed in the NBC 139 and the SIGNALLING of the level of the batteries that supply it. The transmission of the code allows (using the dedicated switches) insertion and disconnection of the alarm system, locking and unlocking of central door locking and opening of boot compartment.

By pressing the button it generates: - OK batteries => flashing led for the entire duration of the pressure on the key - Wasted battery => just 1 flash of the led on pressing the key After a hundred transmissions with low level battery supply voltage, the system cuts off the function of the remote control. It restarts itself only if a new full charge battery replaces the wasted one, otherwise the remote control doesn’t restart itself (saved in EEPROM). The logic stage exists of: - dedicated, integrated circuit - three normally opened pushbutton - led The function of this H/W stage is the generation of the variable code (by modulating the oscillator). Keys’ functions The remote control has three keys respectively called BLOCK, UNBLOCKING and BOOT. The keys operate the following functions: BLOCK Pressing the BLOCK keys the doors will lock and insert the eventual alarm system. Pressing more then 4 seconds the windows and the sliding roof will close automatically (SUPERLOCKING). The movement will interrupt itself if the key’s pressure stop. New pressure for 4 seconds will start the function again. UNBLOCKING Pressure of the unlocking key will unlock the doors, switch the inside lights and disconnect the eventual alarm system (SUPERUNLOCKING). Pressing the key for more then 4 seconds the windows and the sliding-roof will open automatically. BOOT Pressing the key will unlock the boot/rear door, visible from the slight lifting of this one. It will partially disconnect also the eventual alarm system.

Field Strength of Emissions, Prescans in a fully-anechoic room (30 MHz ñ 1 GHz) Rules and Specifications: Sections 15.109 & 15.231 Guide: ANSI C63.4 1997 Measurement Procedure: Radiated emissions are measured over the frequency range from 30 MHz to 1 GHz. Measurements were made in both the horizontal and vertical planes of polarization in a fully anechoic room using a spectrum analyzer with the detector function set to peak and resolution bandwidth set to 100 kHz. All tests were performed at a test-distance of 3 meters. Hand-held or body-worn devices are rotated through three orthogonal axes to determine which attitude and configuration produces the highest emission relative to the limit and therefore shall be used for final testing.
