Key No.7~18
These keys are the single-shot keys and when input is made, signal is output only one time.
3. TRANSMISSION COMMAND
Transmission command is in one word 12-bits configuration. C1~C3 are code bits adaptable to many models,
H,S1 and S2 continous signal and single-shot signal codes ,and D1~D6 are Key input data codes in 6-bits.

As the multiple keying is possible , key No .1~6 are capable of output 63 commands through a combination of
D1~D6 data .
Key No . 7~18 are the single-shot keys for output 12 commands , and 75 commands can be output through a
combination of continuous key (multiple keying is possible ) and single-shot key .
