When entering keys into the receiver, you must strictly account for your actions.

When editing the receiver's system data yourself, you can disrupt its software settings.
If you fail to enter Biss keys, or another coding system, we recommend that you contact specialists for proper tuning or reflashing of the tuner.

To enter Biss keys into the CosmoSat 74xx receiver, you need to perform the following steps

If the Menu does not have the Keys (Keyeditor) item, you need to activate the emulator. To do this:
  • Select the System (MenuUser Preference) item in the menu
  • Move the cursor to the Factory Default item
  • Press the «PAGE/DOWN» key 4 times
  • The Keys (Keyeditor) item should appear in the menu - enter the key editor

In the key editor, we find the encoding of the Biss system and perform the following:

  1. It is recommended not to add new keys, but to edit unnecessary ones.
  2. Set Provider ID to 1F FF 00 (for most channels)
  3. The key name must match the channel name letter by letter, taking into account the case, but it can be shorter than the channel name. So for the channels СТС+7 and СТС+4, the key name can look like СТС
  4. It is necessary to enter the key only while on another channel, otherwise nothing will work.
  5. If everything is done correctly, but the channel does not start showing (and restarting the tuner did not help), you need to go to the channel editor and rename the channel with the same name as the key. This may require renaming the key again, not forgetting about the 4th point!!!
