4-1. ADJUSTING REMOTE COMMANDER
The adjusting remote commander is used for changing the calculation
coefficient in signal processing, EVR data, etc. The adjusting
remote commander performs bi-directional communication with
the unit using the remote commander signal line (LANC). The
resultant data of this bi-directional communication is written in
the non-volatile memory.

1. Using the adjusting remote commander
1) Connect the adjusting remote commander to the LANC terminal.
2) Adjust the HOLD switch of the adjusting remote commander to
2) Adjust the HOLD switch of the adjusting remote commander to

2. Precautions upon using the adjusting
remote commander
Mishandling of the adjusting remote commander may erase the
correct adjustment data at times. To prevent this, it is recommended
that all adjustment data be noted down before beginning adjustments
and new adjustment data after each adjustment.

4-2. DATA PROCESSING
The calculation of the DDS display and the adjusting remote
commander display data (hexadecimal notation) are required for
obtaining the adjustment data of some adjustment items. In this case,
after converting the hexadecimal notation to decimal notation,
calculate and convert the result to hexadecimal notation, and use it
as the adjustment data. Table 5-4-2. indicates the hexadecimal
notation-the decimal notation calculation table.

In the case that the DDS display and the adjusting commander display are BD (
bd).
As the upper digit of the hexadecimal notation is B (
b), and the lower digit is D (d), the intersection “189” of the 1
and
2 in the above table is the decimal notation to be calculated.

When no error occurs in the unit, data 00 is written in the above
addresses (30 to 3B). When the first error occurs in the unit, the data
corresponding to the error is written in the first emergency address
(30 to 33). In the same way, when the second error occurs, the data
corresponding to the error is written in the second emergency address
(34 to 37).
Finally, when the last error occurs, the data corresponding to the
error is written in the last emergency address (38 to 3B).
Consequently, addresses 38 to 3B are updated each time errors occur.
