RF OUTPUT
The Rf output signal can be turned on or off. If changing any programming parameters in the radio, it’s
recommended to turn the Rf off so not to unnecessarily clutter the fl ying space with radio signals. Leave
the Rf output signal ON anytime the model is being controlled.
Enter this screen to perform a range check on the radio system, as fully explained on page 22.
TIMERS
Two timers are shown on the home screen, which can be confi gured in this screen. The timers can be set
to count up or down, and can be controlled by a user assigned switch. The timers can also be controlled
by the throttle stick if desired.
ENTER
this screen and press
or
to move the cursor to the timer feature to adjust for each timer
as desired. Once in the proper place, press
ENTER
to highlight the value. Press
or
to adjust the
time as needed.
To count UP as a stopwatch, leave the timer set to 00:00. To confi gure the timer to count DOWN, set a
time other than 00:00 with a maximum possible start time of 99:59. When used as a countdown timer, a
set of tones will sound at 00:10 and every second thereafter to warn that the timer is nearing the end. After
reaching 00:00, the timer will automatically begin counting up to help track how much longer the model
was operational after the timer ended.
A switch can be selected on the right side of the screen to turn each timer on / off. Place the box on-screen
over this setting and defl ect the switch that will control the timer. In operation, the timer will be stopped
when the switch is in one position. Moving the switch to the opposite position will cause the timer to count.
To reset the timer, move the switch to the stop position and press the
CLEAR
button.
The timer can also be started and stopped by the throttle stick. Move the throttle stick to the minimum
throttle position. Place the box on-screen over this setting and press
ENTER
. When “Choose the control
switch” displays, move the throttle stick up from minimum throttle.
The “START/STOP” screen should show. Moving the stick up or down will show changes to the “THROTTLE”
position value. The “START/STOP” value shows the trip point where starting and stopping the timer will occur.
Move the stick to the position of the timer’s trip point and press
ENTER
. The position value for START/
STOP should now match that for THROTTLE.
Press
ESC
to return the timer setting screen. The throttle stick’s START/STOP position for the timer should
show below the timer settings.
For example, if a throttle stick START/STOP value of +45% is selected, anytime the throttle stick is below
this value the timer will be stopped. Anytime the throttle stick is above this value the timer will count. To
reset the counter, move the throttle stick below this value and press the
CLEAR
button.
The “Tx Battery” timer at the bottom of the TIMER setting screen accumulates the total amount of time
the radio has been operational. This time can only be reset by moving the cursor over “Tx Battery” and
pressing the
CLEAR
button.
DIGITAL SWITCH ASSIGNMENTS
Functions in this screen can support the use of miscellaneous accessories with the TTX850, and can
range from video, still camera, LEDs, etc. More than one accessory could be controlled simultaneously,
and manipulated by the pilot through just one channel on the TTX850. This function requires special SLT
receivers (see those instruction manuals for details).
