RD-20s.
• Controls with T key: Decrease the display brilliance.
• Controls with S key: Increase the display brilliance.
Operation with sub RD-20
When you want to individually adjust the display brilliance for each sub RD-20, do as follows:
• Controls with T key: Decrease the display brilliance. (The variation is smaller than that of the
main RD-20 and RD-502 connected to the main RD-20.)
• Controls with S key: Increase the display brilliance. (The variation is smaller than that of the
main RD-20 and RD-502 connected to the main RD-20.)
Operation with RD-502
The RD-502 simultaneously controls the display brilliance of the main RD-20 and the sub RD-20s.
• Controls with T key: Decrease the display brilliance.
• Controls with S key: Increase the display brilliance.
• Controls with the DAY/NT key: The display brilliance changes as shown in the table below with
every press of the key.
