An UPV provides along the full length of a train:
- information and entertainment program translation from magnetic recordings of МК and МР3/CD types. It is made with the help of two built-in automatic radio-cassette players with the following characteristics:
- fixed tuning of stations in the ranges FM1/FM2 87.5 - 108 MHz, FM3 65 - 74 MHz and in a bandwidth of LW 144 -279 kHz, MW 522 - 1620 kHz;
- automatic frequency adjustment;
- automatic reverse;
- control unit illumination in the “night design” mode;
- LCD-display with a clock;
- electronic adjustment of volume, balance, basses;
- automatic and manual search, memorisation of stations;
- autoloading МР3/CD-player; CD-R/CD-RW-antishock; Intro/Scan/Repeat functions;
- removable control board;
- voice transmission through a microphone;
- light indication of radio cassette player operating modes and indication of device operation in the line;
- simultaneous operation of one radio cassette player and transmission from the other;
- universal time control with the help of an integrated clock module;
- fine sound adjustment.
