SWITCH ASSIGNMENT TABLE 
• The factory default functions activated by the switches and knobs for a 10CA Mode 2 transmitter are shown below. 
• Most 10C functions may be reassigned to non-default positions quickly and easily. 
• Basic control assignments of channels 5-10 are quickly adjustable in 
AUX-CH
 (see p. 46). For example, the channel 5 
servo, which defaults to SWITCH E for retract use, can easily be unassigned (NULL) to allow for easy use as a second 
rudder servo in a mix, or to a slider or dial for bomb door or other control. 
• Note that most functions need to be activated in the programming to operate. 
• 10CA Mode 1, 10CH, and 10CP transmitter functions are similar but reverse certain switch commands. Always check 
that you have the desired switch assignment for each function during set up.

*On the 10CA Mode 2 transmitters, the TOP LEFT SWITCHES are spring-loaded and 2-position; on the 10CA Mode 1, 10CH, and 10CP, those 
switches are on the right side. For consistency, the switch position’s designation remains the same (upper left is F, etc), but the functions are moved to 
match the switch type.
