Tactic TR625 6-Ch - Manual

TR625
TM
2.4GHz 6-CHANNEL TWIN ANTENNA RECEIVER
This receiver is capable of full-range operation
for any aircraft type. Its SLT protocol makes
it compatible with all Tactic brand 2.4GHz
aircraft transmitters, and other brand radios
that include the SLT protocol.
Refer to the instructions with the aircraft to determine the optimum position for installing the receiver. In some aircraft it’s recommended
to fi rst wrap the receiver in protective foam, and then use hook-and-loop material to mount it to the aircraft.
IMPORTANT! Pay close attention to how the antenna tips are routed inside the model. It’s best to orient the antenna tips
at least 5 inches away from each other, preferably pointing at 90° angles. If possible, align one antenna tip horizontally
and the other vertically inside the model.
Linking the TR625 receiver to the Tactic / SLT compatible transmitter ensures sole communication between the two, and prevents
other transmitters from being able to control the receiver.
1. Turn on the Tx.
2. Apply power to the Rx.
3. If the Rx LED fl ashes once and then stays on, the Rx is already
linked to the Tx and you can skip to the next section. Otherwise,
insert a small diameter screwdriver through the hole marked
“LINK” and press the pushbutton until the Rx LED glows red
and then turns off after about one second.
4. Release the “LINK” button.
5. If the linking is successful, the Rx LED will fl ash once and
then remain ON.
6. Test for proper Tx/Rx functionality before use. If the radio
doesn’t appear to have become properly bound, repeat steps
1–5 above.
If the receiver is powered without the transmitter being turned on, or signal from the transmitter is not recognized by the receiver,
the receiver will go to failsafe mode as described in the following section.
The radio system’s failsafe function is controlled by the TR625 receiver, which engages in the event that the signal from the Tx
somehow becomes interrupted. In such case, channels 1, 2, 4, 5, and 6 will hold their last recognized position.
Throttle, channel 3, however, can move to a position which is pre-set by the user during the linking process. The factory default
failsafe position for channel 3 is to move to 0% throttle. The throttle’s failsafe position can be manually set to any other position if
desired, as follows:
1. IMPORTANT: make sure the throttle channel’s servo reverse
setting is in the correct position for the application.
2. Apply power to the Tx, then the Rx.
3a. If using an ESC: do NOT arm the ESC, or attempt to adjust
the throttle’s failsafe position if the ESC is armed. NOTE: If you’re
using an ESC which has a signal loss feature, its pre-set failsafe
position will be irrelevant as the receiver’s failsafe function will
cease the throttle operation if the signal is lost.
3b. If using a combustion engine: do NOT attempt to adjust the
throttle’s failsafe position while the engine is operating. 4. Move the Tx throttle stick to the desired throttle failsafe position.
5. Press and hold the receiver’s “LINK” button. The Rx’s LED
should blink twice. Release the LINK button, and the LED should
stay on continuously. The Tx and Rx should now be linked, with
the throttle failsafe in the new position as set above.
6. Prior to fl ight, check the position of the failsafe. It’s best to
check the system with the propeller removed from the aircraft
and the aircraft restrained.
Check the instruction manual included with the Tactic radio for the proper steps to perform a system check before fl ight.
WARNING! Always make sure that power is applied to the transmitter BEFORE applying power to the receiver and servos,
and the Tx throttle stick is at minimum (idle) position. Failure to do so could result in the model becoming uncontrollable
