Timer
The transmitter Timer can function as either an Up or Down Timer.
Down Timer (default selection)
The Down Timer allows you to adjust the amount of time in 10 second increments to a
maximum of 21 minutes, which will then start a countdown to “0” once activated. The Down
Timer value is normally the length of a race or vehicle run time. The Down Timer can be reset
by selecting Timer Reset or by holding the switch that is assigned to that timer for 3 seconds.
Up Timer
The Up Timer functions as a stopwatch and is useful for determining the available run time in
one tank of fuel or a battery pack.
Using the Timer
1. Assign the timer to a switch or button in the Switch menu.
2. To start or stop the timer, hold the assigned button.
3. To reset the timer, press the timer button for more than 3 seconds.
Switch
The Switch menu enables you to assign any of the seven switches to one of
the following functions. Switches that have a +/- next to the name can be
assigned to different directions. For example, ST trim+ causes right steering
trim to trim the steering to the right. ST trim- trims the steering to the left.
Aux1 and Aux2 can only be assigned to one function at a time. For example,
if Aux1 is assigned to 4WS Mix, then it will not be available as an option on
the switch screen.
