See the “Channel Monitor” section on page 31 for more information. x-Plus Monitor Use of the X-Plus Monitor requires X-Plus to be active. The X-Plus Monitor screen displays the output position for each X-Plus chan- nel graphically and numerically. This is useful to verify program- ming functions, trim settings, mix directions, etc. The numeric value is directly relative to the travel adjust and mix values (e.g., 100% travel adjust equals 100% value in the X-Plus Monitor). The X-Plus Monitor shows the additional channels and requires servos which can be connected to the optional X-Plus module and an X-Plus-capable receiver.
