xR EOE Congratulations on your purchase of the 10OM IC.245E. The 1C-245E fs unique in ity mobility, flexibility und compact size.” Outstanding performance capabilities are produced by the proprietary ICON C-MOS LSI built into each 1C-245E: By itself, the IC245E gives full command of the 144 146 MH: 2 meter band. The IC-245E is & mealtime MHz FM, LIES, CW unit,: Carefully reading this manual will ‘help you pet the most pleasure and effective use from your new transceiver.
A unique COS LSE The COM chip makes the IC-245E 2 revolutionary transceiver. This multi-function chip incorporates bears of COM digital and PLL technology development. Compact size, dual VEO performance and an accurate; stable, digitized frequency readout are possible due to the chip. Pulses generated by turning the dial are counted, thus controlling an up/down counter that controls a programmable divider in'the PLL to chance Frequencies.
SECTION 1ii CONTROLS Front Panel Configuration ‘The front panel controls are shown in Fig. CONTROL or CONNECTION DESCRIPTION Frequency Display Tuning Knob RECEIVE LED TRANSMIT LED Photo Sensor VOL (Volume Control) Knob VEQ Switch Meter The operating frequency display of the set is shown by a 4-figure LED digital indicator with Mz to KHz digits: The frequency displayed is the carrier frequency of each telecommunication (FM. Crossbar CW), thus eliminating returning when'a mode is changed.
Function Switch A switch used to horn on and off the power source and to change from simplex to duplex operation. 10 'SQL (Squelch) Knob A knob used fo adjust the squelch operation level in EM reception. When the set is adjusted to the noise shut-off point with no signal; 2 voice will be audible when signals are received. 11 MIC Connector Use the microphone supplied with the set. An optional desk type ICON microphone, 1C-SM2. can also be used without modification.
25 ACC (Accessory) Various adapters can be sad through terminals in this jack for: frequency control \input, modulation: output, receiver output, T/R change-over control and so oni The table below shows terminal connections of this connector, Care should ‘be taken not to apply voltage other than 0.5V to +5V. o terminals between: Noisy and ‘No.24 a¢ they are connected with the C-MOS IC. Optional connecting plugs are available. 26 Key Jack Insert Kay Plug for: CW operation. ‘Terminal No, Connection 1.
Key Connection Distributes Battery. Ignition Breaker Points C v mitigation Coil C = Capacitor for anise suppression R = Resistor for noise suppression Ignition Noise Care has been taken to suppress ignition noise within the set. However, in some kinds of outs-mobiles; excessive noise may occur. In that case, provide & filter circuit a5 shown in this figure. Remarkable noise suppression is furnished by this arrangement.
Installation (1) Fasten the mobile: mounting ample bracket on'the: lip of the dash with the mounting bolts supplied; {2) Esteban the mobile mounting holder A to the angle bracket with the four ornamental [Screws. (3) Install the set In the mobile mounting holder A, {4) Hook up pawls of the mounting holder B into holed provided on 'the holder A. 5} Clamp the set by tightening: the holder B and lock the Buick fastener by pulling down the knob. Removal Unlock the quick fastens and loosen the holder B.
The installation angle: can be adjusted: over an 187 arc. Loosen screws at both sides and position the set at the most convenient angle for easy operation. Fixed Station Use When the set is used as a fixed station, use the supplied mobile mounting fixtures supplied with the IC-3PA power supply. Power Supply for a Fixed Station The rated power supply voltage of this set is 13.8Y %15%. Use a stabilized voltage power source of 13.8V with current capacity of more than 3A for a fixed station set.
SECTION VI OTHER REMARKS Do not attempt to connect or remove the power cable, antenna, external speaker ot microphone while the power switch is ON: This may damage your set; Do not transmit without connecting the antenna. This set is made for {he negative () round system: The set can not be installed to a car having positive ground without modification. 1f fuses are blown, check the cause of trouble before replacing them with new ones.
HOW TO TUNE Tuning Knob The tuning knob is provided with a click stop and it tunes smoothly even as a mobile station. Frequency drift due to vibration turning the tuning knob is prevented by the click stop. Transmitting and receiving frequencies are shown by four LED (Light Emitting Diodes) digits in the frequency display window in steps of 100Hz, Rotating the tuning dial clockwise will increase the frequency.
Memory This set utilizes 2 C MOS 181 for setting the frequency: The memorized frequency remains as is when the power 13 off, however, the LSD is partially powered. In this set. the function switch need not remain ON (up) fo keep the LSE memory working. However, the memory is lost when the power cable is disconnected from the power source or the AC power source is unplugged. If you wish to maintain frequency memory during periods when power is dis connected, connect batteries as shown in Fig.
