So, you have purchased a MegaJet radio station, installed it in your car. And now the most interesting thing is left for you - to configure it. But how to do that? The method of arbitrary pressing of the buttons will not work. Reading instructions that are replete with scientific radio engineering terms is also not very interesting and takes time. We offer you a short article with practical tips for setting up your radio station:

• The first step is to switch the radio to 240 channel mode. To do this, enter the combination "AM / FM -> ON";
• If you press the buttons incorrectly, you can reset all settings, you need to press "CH9 -> ON" to reset the settings, the screen will display "Reset";
• To switch to the Russian grid, you need to dial the combination "DW / M2-> ON". After that, you can see on the screen that the frequencies end with 0. On the Euro grid, the frequencies end with 5, please note that most often drivers and truckers use the European band grid;
• You can check the radio in this way by turning on, for example, the channel for truckers C15E AM at a frequency of 27.135, where “C” is the grid, “15” is the channel number, “E” is the European band grid, “AM” is amplitude modulation;
• You can set up the antenna yourself. You can install the original antenna or purchase another brand that is compatible with your radio.

To fully configure your radio, in any case, you need to read the instructions or take the help of specialists.

But if you do not want to deal with the manual or you simply do not have time for this, then we suggest using the services of our specialists in setting up and programming radio stations. They will do the job professionally. short time, will give you valuable recommendations and tips for use.
