ADJUSTMENT REMOTE COMMANDER
The adjustment remote commander is used for changing the cal-
culation coefficient in signal processing, EVR data, etc. The ad-
justment remote commander performs bi-directional
communication with the unit using the remote commander signal
line (LANC). The resultant data of this bi-directional communica-
tion is written in the non-volatile memory.

2. Precautions Upon Using
the Adjustment Remote Commander
Mishandling of the adjustment 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 adjust-
ments and new adjustment data after each adjustment.

DATA PROCESS
The calculation of the DDS display and the adjustment 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 nota-
tion, calculate and convert the result to hexadecimal notation, and
use it as the adjustment data. Indicates the hexadecimal-decimal
conversion table.
