■

Selecting and setting a channel

Use the ENTRY key on the load unit to select a channel. The selected channel is
con

gured on the frame.

• LOAD, INDEP, or DISP keys can also be used to select a channel.

■

Setting

On the frame, press the function key and then turn the rotary knob to set the value. If
you press an invalid key, a buzzer sounds.
