line6 floor pod plus中间的周边效果怎么关？请各位高手指教一下！

以下来源于英文说明书，附大意
To turn the effects off, use the C / FX footswitch when in On/Off Mode. See Chapter 1
for more info.(On/Off Mode: This mode lets you to turn effects or the Amp Model on and off with
your feet. Footswitches A-D now turn on and off the Amp Model, Solo boost, FX,
and Delay respectively. In this mode, the footswitch lights will illuminate Green to
indicate the On state of each function.)

同时按bank up（bank↑）bankdown（bank↓）切换到on/off（开/关）模式，两个bank中间有指示灯；然后按C/FX键切换效果（effect）开关（指示灯绿色）

你在说什么？？
