User manual ICOM IC-PW1

[. . . ] USE antenna(s), such as a well-matched 50 antenna and feedline. For radio communications, the antenna is of critical importance, along with sensitivity. SYSTEM REQUIREMENTS · IBM PC/AT compatible computer · An RS-232C serial port (38400 bps or faster) · Microsoft® Windows® 95 or Microsoft® Windows® 98 · Intel i486DX4 processor or faster (Pentium® 100 MHz or faster recommended) · At least 16 MB RAM · At least 10 MB of hard disk space · At least 640 × 480 pixel display (800 × 600 pixel display recommended) i OPERATING NOTES The IC-PW1 may receive its own oscillated frequency, resulting in no reception or only noise reception, on some frequencies. The IC-PW1 may receive interference from extremely strong signals on different frequencies or when using an external high-gain antenna. Versions of the IC-PW1 which display "CE" on the serial number seal, comply with the essential requirements of the 89/336/EEC directive for Electromagnetic Compatibility. CAUTIONS RWARNING!NEVER connect the receiver to an AC outlet.

The following sub screens are available. · When inputting a frequency outside of the allowed receive frequency range, the previously selected frequency is automatically selected after clicking [Enter]. D Using the simple function receiver screen q Click [MENU] and select the `Function Controller' when it is not displayed. w Click [FREQ J] or [FREQ K] on the function controller to set the frequency according to the selected tuning step. · The frequency changes according to the selected tuning steps. See the next page for selecting the tuning step. · When clicking and holding either button the frequency scrolls up or down. 17 3 BASIC OPERATION s Setting a tuning step When using the tuning dial or [FREQ J]/[FREQ K] buttons to change the frequency, or when a scan function is activated, the frequency changes in increments determined by the set tuning step. The following tuning step are available. · 1 kHz · 5 kHz · 6. 25 kHz · 9 kHz · 10 kHz · 15 kHz · 20 kHz · 25 kHz · 30 kHz · 50 kHz · 500 kHz · 1 MHz · 10 MHz s Receive mode selection Receive modes are determined by the physical properties of the radio signals. The receiver has 3 receive modes: FM, AM and WFM modes. Typically, AM mode is used for the AM broadcast stations (0. 495­1. 620 MHz) and air band (118­135. 995 MHz), and WFM is used for FM broadcast stations (76­107. 9 MHz). When using the automatic mode function, a receive mode, tuning step and filter selection are automatically selected after inputting a frequency. · 12. 5 kHz · 100 kHz D Using the multi-function receiver screen Click [TS J] or [TS K] to set the desired tuning step. · The selected tuning step is displayed in the function display. D Using the multi-function receiver screen Click [FM], [WFM], [AM] or [AUT-M] to select the desired receive mode. D Using the simple function receiver screen q Click [MENU] and select the `Function Controller' when it is not displayed. w Click [TS J] or [TS K] on the function controller screen to select the desired tuning step. · The selected tuning step is displayed in the information display if the information display is in use. D Using the simple function receiver screen q Click [MENU] and select the `Function Controller' when it is not displayed. w Click [AM], [FM], [WFM] or [AUT-M] to select the desired receive mode. 18 BASIC OPERATION 3 s Automatic mode selection An automatic mode function is available to automatically set the receive mode, IF filter passband width and tuning step after inputting a frequency.
