I can't understand either from reading the instructions, but you may have to try various combinations. Try these procedures first and see if they work for you.

If you are setting up an AV device please make sure that a tape or disk inserted.
Look in the BRAND CODE LIST to find the 3 digit code for device, brand name, and model.
Press and holdthe [SET] key, then press the device key e.g. [TV1][VCR][SAT] etc.
When the LED indicator lights up release both keys.
Input the 3 digit code for the device. The LED indicator will go off if the code number is correct. If the code is incorrect the LED will flash twice and remain in the set-up mode. Input another code from the BRAND CODE LIST.
