corresponding setting menu.
 Press #Data to set the transmission data length per frame to 5bits, 6bits,
7bits or 8bits.
Note, if the “#Data” set is less than 1byte (8bit), the most significant bit is
dropped in the output. For example, when “#Data” is set to 7bits, the 0 (in bold)
is not output when outputting the data 0x08 (00001000).
 Press Verify to set the verification mode to None, Odd, Even, Fixed0 (the
“verify” bit is always set to 0) or Fixed1 (the “verify” bit is always set to 1).

 Press #Data to select 1Byte, 2Byte or 3Byte.
Note, data per frame (#Data) is limited by the current output data length (refer to
“To Set the Output Data Length”). For example, when the output length is
1Byte, the #Data menu cannot be set to 2Byte or 3Byte.
 Press Rate and use the knob or number keypad to input the desired rate and
