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.
To reset either timer, while in the homescreen, press and hold CLEAR, then press to reset T1 or press
to reset T2.
CAMERA GIMBAL
The TTX850 includes the ability to control a camera which might be attached to a model, housed in an
optional camera gimbal which can provide pan and/or tilt movements.
For PAN CH, highlight and select the auxiliary channel to control sideways (pan) movements of the camera
gimbal. Directly underneath for CTRL, select which switch to control this function. Then set the RATE or
maximum travel distance this function can move when the switch is activated. Repeat these procedures
for up/down TILT movement of the camera gimbal.
For the “SMOOTH” function, “OFF” causes the servos to move at a linear rate compared to the movement
of the control lever for quick pan/tilt the camera. “ON” causes the servos to move at an automatic and
slowed rate which is non-linear to the movement of the control lever, for very gradual camera movements.
DIGITAL SWITCH ASSIGNMENTS
Functions in this screen can support the use of miscellaneous accessories in the model, 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).
