SECTION {I DESCRIPTIVE THE MOST COMPACT 144MHz MOBILE The smallest: 144MHz mobile available, the 1G-27A/E meas tires only 38 millimeters high by 140 millimeters wide! As an added bonus, the 1C:27A/E through ICON engineering, is able continental an internal speakerphone: provide sage of mounting and make the munition small compact completes package. HIGH OUTPUT POWER n such incredibly: small package, the IC:27A/E is able to provide 25 watts of output power.
[3=Ton Lo IR TI UNPACKING Cara fully remove your transceiver from the packing carton and examine it for signs of shipping damage. Should any be apparent, notify the delivering carrier or dealer immediately, stating the full extent of the damage. Otis recommended you Keep the shipping cartons: In the scent storage. moving: or reshipment becomes necessary. they come handyman.
POWER REQUIREMENTS The: transceiver: is supplied ready: to operate from any ‘regulated [13.8V. DG, 6 ampere negative ground source. An automobile: 12 volt; negative ground, System is usually mare than adequate. Some note must be taken, however, of the condition of the vehicle's electrical system. Items such a5 low: battery, worn internationalization, poor voltage regulator, etc., will impale operation of your transceiver:as well absinthe vehicle.
ANTENNA The most important single item that will influence the performance of any communication system it the antenna.
SCAN START/STOP BUTTON Starts and stops any of the scan functions.: When depressing it o restart the scan. it will start from the memory channelize frequency: displaced. TUNING RATE SWITCH Selects the tuning frequency steps: When this switch Is pushed in; the frequency changes'in kHz steps (European version:: 12:5KHz steps) by turning the TUNING: CONTROL.
When receiving on g frequency with:a memory channel; by pushing the priority button; the receiving frequency will go 1o the VEO frequency previously set for 3 moment ‘every five seconds. SQUELCH: CONTROL: Turning this control clockwise: sets the squelch threshold higher: i To turn OFE the squelch Unction; worn this control completely counterclockwise: VOLUME CONTROL and :POWER SWITCH When the control is turned completely: counterclockwise the power s OFF.
22, 23. 25. RECEIVE INDICATOR ruminates when the squelch is opened: in the receive mode, TRANSMIT INDICATOR Terminates in the transmit mode, DUPLEX INDICATOR Illuminates when the set iy in the DUPLEX model’ “DUPE! shows the transmit frequency will be below:the receive Frequency, and “DUP shows the transit frequency will be above the receive frequency.
SECTION V. OPERATION HOW TO TUNE The following inst Ructions ‘are for the tuning. Please read carefully and understand fully before turning Omnivorous. ‘Proper tuning i necessary: for optimum operation.: PRESET FREQUENCY When the POWER switch is first turned an or the CPU RESET switch is pushed, the FREQUENCY DISPLAY willies 247 00" representing 147.000MHz {European version and Australian version: HAB 00" representing 145,000MHz), and the MEMORY CHANNEL DISPLAY will be "0 representing memory ‘channel 8.
FOR EXAMPLE: 11 145 750MHz is set with the VFO A, and the VFO switch is pushed to select the VFO B, the frequency readout will show the VERGES frequency. but 145, 750MHZ s still stored in the VEO Immemorial :Pushing the VO switch again 1o return 1o the VEO A will be displaced on the readout, Accordingly i the switch: is pushed swain. the frequency that was set with the VF Bi will spear: This allows you:to set a certain frequency with one VEO.
H you sangs the receive frequency from 145.726MHz to 145.676MHz, the transmit frequency will change from 1145:125MHz 16 145.076MHz, 50 now vou cray access & repeater. Pushing the “+DUPLEX" button changes: the ‘transmit frequency: to 600K Hz above the decisive frequency I you set the receive frequency 1o 1451 MHz, the transmit frequency will be 145, 725MHz. This function will be available with goy Floor MEMORY: CHANDELIER.
MEMORY CHANNEL OPERATION MEMORY CHANNEL SELECTION When the: power switch first furred ON or the CRUISER button is pushed, the set initially operates in the VEO mode and memory: channel number 20 is displayed.
MEMORY WRITE [PROGRAMMING THE MEMORY CHANNELS] ‘Any operating frequency, duplex ‘mode. offset frequency and sub audible tone frequency (USA version only) can-be memorized into-a memory, 1.0 Se tithe operating frequency to desired one using a'VFD: i For example setting for 7145725 MHz busing VEO BL 20 Pushiness: MEMORY: switch o set in the MEMORY .CHANNEL mode, then select a memory channel 1o be used by turning the TUNING CONTROL . For example select it at memory channel 5. 3.
SCANNING OPERATION MEMORY SCAN This is:used toucan the nine memory channels continuously 1 2 3 Program nine desired frequencies into MEMORY CHANNELS 0~ 8. Push the MEMORY switch 1o select the MEMORY CHANNEL mode. Pushiness SCAN START/STOP (5/S) button, and the operating frequency 'starts scanning the programmed: frequencies {n the MEMORY :CHANNELS from the displaced ‘channel ito the ti ghee memory channels in order.
4. While the SQUELCH s engaged. the squirrel opening as g signal 15 received will stop the scanning automatically on the frequency. If the RECEIVE indicator s it because ‘the SQUELCH s not engaged, the scan does not start: B To theosophist scan operation; push the SCAN START/STOP {S/S) button: i Pushing the S8 buttonwood restarts the scan from the frequency gt which it stopped. 6. When the scanning has ‘automatically stopped on .

By pushing the TONE SELECT: button: the FREQUENCY. DISPLAY shows a tone number instead of the operating frequency.
When selecting a number except 700" the tone circuit is turned ON and the letters “TONE® are indicated on the frequency display) When selecting the number: 2007 the tone circuit is furn ad OF And the letters TONE gre also turned OFF. This tone umber is memorized introit VEO ot MEMORY. CHANNEL which is selected when the tone number has been set. The submersible tone s transmitted when the set Is in: DUPLEX mods only even if the tone indict: tor s illuminated.
