Подробные указания по применению содержатся в руководстве пользователя.

Wide frequency range and large channel capacity The IC-290 A E series covers a wide frequency range in one version ( VHF 136 ­174 MHz, UHF 400 ­ 470MHz). The 512 memory channel capacity with 128 zones allows you to divide and store a variety of flexible channel groupings. Wide, middle and narrow channel bandwidth (25/20/12. 5kHz)* is also programmable. * Programmable 25/12. 5kHz or 20/12. Digital mode capability An optional upgrade to 6. 25kHz digital operation is planned in the near future. I c o m i s c u r r e n t l y researching the regulatory requirements for use in Europe for the 6. 25kHz 4FSK/FDMA technology. Built-in inversion-type voice scrambler The built-in inversion type voice scrambler provides secure conversation.
