There are two Remote modes:

serial port command RMT 0. Set the unit into Remote mode via serial port RMT 1
command.
b) Local Lockout: In this mode the unit can be returned to Remote mode via the serial
port RMT 1 command or by turning off the AC power until the display turns off and
then recycling AC power. In local Lockout mode, the front panel REM/LOC button is
not active. Set the unit into Local Lockout mode via serial port RMT 2 command.
