Congratulations on your purchase of the ICON IX-245. The IX-245 is unique in its mobility, Flexibility and compact size. Outstanding performance capabilities are produced by the proprietary ICON € MOS Overbuilt into each 1-245 . By #self, the IC:245 gives full command of the 144--148MH2 2 meter band.
A unique C:MOS LSI The ICON : chip makes: the [C:245 3 revolutionary: transceiver. Whig: multi-function chip incorporates years of COM digital and PLL technology development. Compact size, dual VEQ: performance and an accurate stable, digitized frequency readout are possible doe 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 change frequencies. Crystal controlled: oscillator-accurate Revels are produced.

Photo Sensor 6 VOL (Volume Control) Knob T VFO 8 Meter The operating frequency display of the set is shown by a 4-figure LED digital indicator with MHz to KHz digits. The frequency displayed is the carrier frequency of each communication mode (FM. S§B or €W), thus eliminating returning when a mode is changed.

When the set is adjusted to the noise shut-off point with no signal; a voice will be audible when signals are received. Use the microphone supplied with the set: An optional desk type ICON microphone, 1C-8M2, can also be used without modification.
Terminal No, Connection 1 Output from discriminator: 2. DC 138V in conjunction with power switch operation. 3. Connected to hasp-totalkc TR, changeover switch. When' grounded, set operates in transmission mode. 4. Output from receiver detector stage. Fixed output regardless of AF output or AF gain control level, 5.0 TX shutdown terminal. When grounded, no RF power is transmitted. 6. DC 9V available when transmitted. {relay can not be directly actuated). 7. Input for external ALC voltage. 8. Ground: 9.

However, in some Kinds of automobiles; excessive ‘noise may scour. In that case; provide a filter circuit as shown in this figure. Remarkable noise suppression is furnished by this arrangement.
Installation (1) Fasten the mobile mounting angle: bracket on’ the lip ‘of the dash with the mounting bolts supplied. (2) Fasten 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 holes provided on the holder A {5) Clamp:the set by tightening the holder B and lock the quick fastener by pulling down the knob.
(2) The installation angle can be adjusted over an 18° 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 a5 g fixed station; use the suppl 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 13.8V & 15%. Use a stabilized voltage power source of 13.8V. with current capacity of more than 3A for a fixed station sei.

not attempt to connect or remove the power cable, antenna. external speaker or microphone while the power switch is ON. This may damage yous set. Do not transmit without connecting the antenna. This set is-made for the negative () ground system, The set can not be medalist to a car Having positive ground without modification, If fuses are blown, check the saute of trouble before replacing them with new ones. 1f the power switch is turned on and off rapidly.
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 furring the tuning knob is prevented by the click stop. Transmitting and receiving frequencies are shown by four LED (Light Emitting Diodes) digits [nth frequency display window in’ steps of 100Hz, Rotating the tuning dial clockwise will increase the frequency.
The has 2 built in circuit, which will automatically reverse the relationship of the dual CEO's in the duplex mode, In duplex (TX frequency *A” VFQ, RX frequency “B” VFO) set the normalize Hz difference between the transmit and receive frequencies (TX-600KHz). When the Reeve frequency is brought up to 147 000MIL frequency, the receiver display will i flash on and off. this will continue even: when the tuning control irritated until the transmit frequency reaches 147 000MHz.
Memory This set utilizes 4 C MOS LSI for setting the frequency. The memorized frequency reaming as is when the power iy off, however, the LSI 15 partially powered. In this set; the function switch need not remain ON (up) to keep the 18I memory working. However, the ornery is lost when' the power cable js disconnected from the power source or the AC power sours is unplugged. If you wish 1o maintain frequency memory during periods when power is disconnected, connect batteries as shown in Fig.
