■ Panel switch modes

The panel switch on the LA-1240/1250/1350/4350 has three modes: Primary, Secondary, and Power On.

• Primary mode (Function 1 switch)

This is the normal mode for panel switch operation. The functions indicated by the black text printed in the center of the panel switch will be activated.

- Secondary mode (Function 2 switch)

The secondary mode is activated when the [2nd] panel switch is pressed and the 2nd mark is displayed on the LCD screen. The function is printed in blue letters above the panel switch.

• Power-on mode (combination switch)

The power-on mode is activated by pressing the power switch simultaneously with the power switch. The keys used for switching between selection items and setting values, and for confirming settings, are specifically called setting switches. The function of power-on mode is indicated in gray text at the bottom of the panel switch.

【Note】

* Normally, pressing and holding a panel switch will sequentially cycle through the settings. However, some panel switches may perform a different function when pressed and held continuously. Please be careful.
