SECTION Il DESCRIPTION The ICON 1-201 transceiver for: 2m Band is 2 precision built ‘high performance -transceiver, providing SSB (LIB and BALLS. FM and CW modes of operation with an output power of 10 watts. This is an extremely durable transceiver which has state of the art devices such as integrated circuity, fled ‘effect transistors, var actor and zen er diodes edginess into g tight knit straight forward electronic design throughout both transmitter and receiver: Reliability, low current demand.
ION T INSTALLATION UNPACKING Carefully remove your ‘transceiver: from the packing ‘carton and examine for signs of damage. Should any damage be apparent, notify the delivering carrier or dealer immediately. stating the fall extent of the damage. 11 Is recommended you keep the shipping ‘cartons. Iy case storage or reshipment I8 necessary. they come in handy: ACCESSORIES The following necessaries are packed with the transceiver. (2} Microphone (500 ohms) .
1f un AC power supply other than the matching IC-3PU is used, be sure it is adequately regulated: for both: voltage and: current. Low: voltage: while: under load will not give satisfactory results from your transceiver. Receiver gain and transmitter output will be greatly impaired. 1t supply voltage happens to decrease 1o less than 10,5V DC, the operation of the receiver will be suspended in ‘order fo prevent commiseration. This indication will be shown by the center meter He ht 'going out.
36 3.7 3.8 MICROPHONE A high quality dynamic microphone is supplied with your transceiver. Merely plug it Into the proper receptacle on the front panel. This microphone is of 500 ohms impedance with a normal output of 6mV. Should vou ‘wish to use a different microphone, make certain: i 18 of equal impedance and-output Revel: EXTERNAL SPEAKER ‘An external speaker jack and plug is supplied with your unit, if another speaker or headset use s desired.
SECTION IV CONTROL FUNCTIONS 4.1 FRONT: CONTROL € 1) Function Switcher: The Ital AUB, €& D are for extra crystals. In the EXT postilion; the ‘output frequency s controlled by another VFO connected to the accessory 9 pin socket. ' VEQ position is the Main VEO. (:2) Power Switch: for AC and DC: {3) Tr Switch: T for Transmit and R for Receive. {47 S0L Control. ' Adjusts squelch threshold. {.S) CAL: For calibration. (6) YOL: Controls audio volume, (7} MIC Gain: For adjusting modulation level.
4.2 4.3 REAR CONTROL (1) GND: Connect to ground to prevent 2 possible electric shock. (2) Key Jack: For CW keying, : (3) EXT SPK Jack: The external speaker impedance should be 8 ohms. The use of the external speaker jack will disable the internal speaker. (4} DC Socket: ‘A DC cord is provided. The RED wire is positive and the BLACK wire is negative. Socket: Accepts the exclusive IC-3PU. By inserting the 1C-3PU the power source is switched from the DC to the AC automatically. Remove the 1C.
SECTION V OPERATION 5.k 5.2 5.3 INITIAL REPARATION Make such the power switch sin the ‘OFF position and the T-R switch {8’10 the *R’ position. For AC operation using the exclusive 10.3PU, power supply, make sure the AC voltage of the 1C-3PU is set for your AC line voltage. The IC-3PU s for 117V or 220V AL ‘ For DC operation, note the IC-3PU must be removed from the 1C.201, then connect the DC power cord to the DC power source and black deaf to the negative side.
In'the CAL position of the squelch control knob, the Marker will work. The Marker frequencies of 0, 500K, 1000KHz can be adjusted accurately by these frequencies on the dial scale. (2) . Adjust the tone in receive as you desire with the tone control, located under the access caver. (h) I overload or cross modulation ete. occurs, adjust the RE Gain {o the best level. TRANSMITTING Please monitor the frequency before transmitting. a) Set the MIC pain control to 1/2 open.
CW Break-in adjust: (1) Set the mode switch in the CW position and the keyed will' automatically switch the 1-201 1o transmit. . with the VOX circuit, the return to receive time i3 adjusted by the Break din time constant control. Turning counter clockwise shortens this time, Remember to turnoff the VOX control switch when not using VOX. FOR REPEATER USE You can transmit at 600KHz below any receive frequency for repeater use by placing the Course Switch in' the Duplex position.
