Range Test; Automatic Test - Jeti DUPLEX Serie-2.4EX Bedienungsanleitung

Plug-in the shorting plug into the connector "Ext." and switch on the receiver. Then switch on the
transmitter. If pairing was successful the transmitter will confirm this by a short beep (by a lower and then a higher
tone). If no confirmation of a successful pairing occurs, try to repeat the whole procedure or try to verify via the
JETIBOX whether the receiver is in „Normal Mode" (a receiver in „Clone Mode" is not allowed to transmit and hence
cannot confirm pairing). After pairing confirmation remove the BIND PLUG from the receiver connector.
Verify correct reactions of the model to transmitter commands (servo deflections have to follow corresponding stick
deflections). If not, check whether servos are plugged into correct positions and the receiver is correctly adjusted
(adjustment of mixers etc.). DUPLEX receivers can be reset to original state by the JETIBOX (connected to the receiver)
with the help of the menu Autoset-normal.
DUPLEX Tx modules are adapted to cooperate with transmitters working with PPM signals. If the transmitter is
switched to PCM mode or the installation has not been performed properly, the transmitter module will emit a
repeated allert tone (3x long beep).

Range test

Before initial utilization of the transmitter (or receiver) it is advisable to make a range test and thus verify correct
functions of the transmitter and receiver HF circuits. The transmitter can be switched to the test mode by the JETIBOX
or by the BIND PLUG.
After connection of the JETIBOX to the transmitter select the item "Range Test" and push the button U (upward
arrow). The transmitter will be switched to range test mode and the transmitted power will be decreased to less than
10%. This situation is reported acoustically by interrupted beeps (short and long tone). After pushing the button U
again (upward arrow) the transmitter returns to normal state, the output power increases to the normal value and
beeping ceases. Test mode activation by means of the BIND PLUG commences analogical to receiver pairing as shown
above. However, after the pairing procedure keep the shorting plug plugged in the receiver. As long as the shorting
plug remains plugged in, the transmitter will stay in range test mode. In this mode the transmitter behaves in the
same way as if range test would have been activated by the JETIBOX. In order to stop this mode remove the shorting
plug from the receiver.
Place the model and transmitter at least 80 cm high above ground. A correctly working transmitter and receiver in test
mode should have a range of at least 50 m. If not, first of all verify correct antenna installation (transmitter and
receiver). If the test still shows no success, do not use the equipment and contact your dealer or a service center.

Automatic Test

The TX module comprises an automatic test system as well. After switching on the receiver and transmitter a quality
evaluation of the transmission path including all antennas is being performed. The result is reported 1 second after
switching on of the transmitter by an acoustic signal of the TX module. No signal at all after lapse of this period
signifies a flawless transmision path. An impaired transmission quality is indicated by one to four tones of the TX
module. One single tone can already occur if the model is slightly further away of the transmitter, but the transmission
path is OK. If more tones are released check the TX antenna connection as well as positions of the RX
antennas and make a range check.
