A list of possible hazards follows: I. Explosive Atmospheres To ensure safety, make sure that the radio is off While fueling the vehicle. When the radio is mounted in the back of the trunk, never have containers of fuel in the trunk of the vehicle“ Interference to Vehicular Electronics Systems Typical types of electronic devices that malfunction are Electronic fuel injection systems, electronic anti-Skid braking systems, etc., The reason for this is due to the lack of protection from radio frequency energy present when transmitting. If the vehicle contains such equipment, consult the dealer of your vehicle and enlist his aid in determining if such electronic circuits perform normally when the radio is transmitting. Dynamite Blasting Caps Dynamite blasting caps may be caused to explode by operating a radio within 500 feet of the blasting caps. Always obey the "Turn Off Two Way Radios" signs posted where dynamite is being used. When transporting blasting caps in your vehicle: a. Carry the blasting caps in a closed metal box with a soft lining. b. Leave the radio OFF whenever the blasting caps are being put into or removed from the vehicle. Radio Frequency Energy Do not operate the transmitter when a person is outside of the vehicle within two feet of the antenna! Failure to heed this waming may result in bums or related physical injury to the person. Liquefied (LP) Gas Powered Vehicles Mobile radio installations in vehicles powered by liquefied petroleum gas with the LP gas container in the trunk or other sealed-off space within the interior of the vehicle must conform to the National Fire Protection Association standard (NFPA) 58 requiring that: a. The space containing the radio equipment shall be isolated by a seal from the space containing the LP gas container and its fittings. 1). Outside filling connections shall be used for the LP gas container. c. The LP gas container shall be vented to the outside of the vehicle. 5mm 8M052X047o dB Receiver Intermodulalion >65 (18 Receiver Conducted Spurmui Emissions <—57 dBm Trmsnlitlcr Conducted Spurious Emissions 43 dB Input Impedance 50 Ohms OuLpuI Impedance 50 Ohms Input VSWR <|.5:1 Output VSWR <1.5:1 Power Sum Vulmgc 117V AC Power Consum (Ion <2A AC Mechanical Prugrznurrring AIarms/Mnnitnring RF Connwmrs N chplacles Frequency of OPCHMIon Power Envimnmenul m, IIumidIly @ (mtput I’vwcr VSWR 50 "c (122°F') Opernzmg 49 lo +50“?

Its receiver section receives signal from the units in the field. The transmitter transmits the RF signal to the units in the field. EFU'I'LRECOM 5 9 .... ...n.... 8M052X04-01 REV. l] 5.0 MAIN FEATURES The MOBITEX AlRBASE 900 is a fully software configurable, Synthesized, narrow band device, with 20 Watt output power capability. It is available in the 900Ml—lz band. Its purpose is to receive a single RF channel, amplify and filter the channel signal and decode baseband data. On the transmit side, it receives baseband data, filters the signal and transmits it as RF signal. The Front End (FE) stage receives a single channel off air using double heterodyne principle and downconverts the signal to an Intermediate Frequency (IF) stage The Intermediate Frequency performs most of the signal filtering required for a given frequency band and channel spacing. The rigorous filtering allows only the desired signal (channel) to pass and to be amplified assuring that all undesired signals on other frequencies are not transmitted. The personality of the unit can be programmed directly from a personal computer via front panel serial port. The MOBITEX AIRBASE 900 software resides in Flash memory and can be upgraded serially without opening and retesting the unit Software upgrade/change can be performed remotely in the same way as personality change. The chassis of the MOBITEX AIRBASE 900 is made of aluminum. The rugged construction of the unit minimizes microphonics and internal feedback. The RF connector is the N receptacle 8M052X04-01 REV. n 6.0 BLOCK DIAGRAM AND DESCRIPTION The block diagram of the MOBITEX AIRBASE 900 is shown in 8D052A14 drawing. The MOBITEX AIRBASE 900 consists of these blocks: Front End, Intermediate Frequency, Power Amplifier and Controller module. RF duplexer, RF preamplifier, attenuator and a power supply. 6. 1 FRONT END Front End starts with a band-pass filter that filters out of band unwanted frequencies. It is followed by a low noise amplifier which can be switched in/out of the signal path under software control. A software 30dB controlled attenuator is next. It is used to control input sensitivity and to lower intermodulation products for stronger input signals, The next two stages consist of a Voltage Controlled Oscillator (VCO), mixer. bandpass filter and an amplifier. These two stages implement double heterodyne down conversion to Intermediate Frequency of 45.0MHz. Voltage Controlled Oscillator frequencies are based on a common Temperature Compensated Crystal Oscillator (T CXO). 6.2 INTERMEDIATE FREQUENCY Proper selectivity of the MOBITEX AIRBASE 900 is achieved by the Intermediate Frequency stage. The selectivity is assured by the input filter together with other filters in this stage. The signal path continues with an Automatic Gain Control Loop (AGC). The Automatic Level Control Loop maintains a constant signal level irrespective of the input signal level The IF signal is used to produce baseband data signal and provides Received Signal Strength (RSSI) indication. 6.3 POWER AMPLIFIER The Power Amplifier is capable of delivering up to 20W on the input/output connector. A band- pass filter filters out of band unwanted signals. The driver and the power amplifier provide the required output power. The output power level is set under software control. The real output power is compared with the desired output power level. An Automatic Level Control Loop adjusts the real output power to be precisely equal to the preset level. An output low-pass filter assures that no unwanted higher harmonics are present on the output of the MOBITEX AIRBASE 900. The reflected power is monitored and the output power is reduced when the reflected power increases. 6.4 RF PREAMPLIFIER AND ATTENUATOR The RF Preamplifier and attenuator are connected to the receiver input. SIMISZXM-m REV. 0 _——._—_————-—— 6.5 RF DUPLEXER The RF duplexer splits the low and high frequencies for the receiver and the transmitter, respectively, 8M052X04—01 REV. 0 7.0 SET UP 7.1 PROGRAMMING SOFTWARE INSTALLATION Futurecom 6A046X02 Programming Software must be installed on a personal computer which will be used for the MOBITEX AIRBASE 900 field system installation.
