User manual ICOM IC-PW1

[. . . ] 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 a power source of more than 16 V DC such as a 24 V battery. only (FCC information) CAUTION: Changes or modifications not expressly approved by Icom Inc.
