5.4 - Special Command Codes

Special codes allow the remote controller to perform functions not available or not necessary under local control.

Some special codes consist of a command code and one or more data codes that further define the special code.

Therefore, these codes may be made up of more than one byte.

Table 5.3 is a summary of these special codes.
