Safety instructions Safety instructions Make s ure to read and o bs e rve the fo llo wing o pe rating and s afety ins tructio ns ! Knowledge of these operating instructions and their observance are a prerequisite for safe use as well as safe operation and maintenance. The following basic safety instructions and warnings are an essential component of these operating instructions and are fundamentally important for product handling.
First identify the error and troubleshoot it. In particular, have the radio control transmitter and the receiver inspected at an authorised MULTIPLEX Service Centre (see section 10.1 "Specifications" on page 212) at regular intervals (every 2 to 3 years).
Page 16
(up to a few days). Thereafter, perform a careful functional test. In case of major condensation, have the device inspected at an authorised MULTIPLEX Service Centre (see section 1.2 "Contact" on page 9).
Safety instructions Safety instructions for the transmitter battery The transmitter battery is responsible for the power supply to this device, and plays an important role in operational safety. The charging circuit integrated in the transmitter matches the battery. Do not charge the battery outside the device. Batteries are not toys and must be stored out of the reach of children.
Safety instructions ESD notes for electronic sub-assemblies The sub-assemblies of radio control transmitters (main circuit board, RF module, Channel-Check module, Scanner module) are fitted with electrostatically sensitive components. These parts can be destroyed, suffer imperceptible damage or have their useful life shortened if static discharges take place (potential equalisation through electro-static discharge) when the sub-assembly is touched.
Safety instructions Intended use The PROFI TX transmitter is intended exclusively for operation of models by radio control. Always follow the switching on/off sequence in order to avoid any uncontrolled, dangerous start-up of the power system: Switching on 1. Transmitter 2.
Page 20
Safety instructions Use cables with sufficient cross-section. Do not coil up or shorten the receiver aerial. Do not lay the aerial on or close to electrically conductive components. Deploy aerials outside of fuselages with a shielding effect (carbon fibre, metallic painted finish). Observe also the advice included in the relevant receiver operating instructions! ...
Page 21
Safety instructions Pre-flight checks Charge the transmitter, receiver and flight batteries carefully, and verify their state of charge at regular intervals. Ensure that the correct model memory is active. Carry out a range check (see section 3.6 "Range check" on page 47). ...
MULTIPLEX goods that were directly affected by whatever incident gave rise to the damage. This does not apply if MULTIPLEX is obliged to accept unlimited liability in accordance with mandatory law for deliberate or gross negligence.

Transmitter 3.4.1.2 Charging the battery using the plug-in charger Proceed as follows: Lift the device (the recessed control for the sliding latch is located on the underside of the case). 2. Slide the sliding latch towards the device centre. 3. Connect the supplied USB cable to the plug-in charger and to the mini USB PROFI TX socket on the 4.
Transmitter 3.4.4 Battery management PROFI TX records the current during transmitter operation and while loading the transmitter battery. The available battery charge is calculated on the basis of the power meter reading, the temperature and the voltage. The remaining operating time (time to empty) is calculated from charge and current and is shown on status display #2 (see page 87).
Transmitter Switching the transmitter on / off Charge the transmitter battery! PROFI TX is supplied with a partially charged transmitter battery. You should charge the battery prior to setup. Observe the notes on charging (see section 3.4 "Transmitter battery" on page 41). 3.5.1 Switching on To switch on the device proceed as follows:...
Transmitter Switching on in Binding mode Press and hold the ¡ button until the status display is shown (see section "Binding" on page 48). Switching on for range check Press and hold the § button until the status display is shown. The device starts up with reduced transmitting power when the range check is performed (see section 3.6 "Range check"...
Transmitter Range check Regular range checks are necessary for ensuring the reliable functioning of the radio control system and for timely detection of changes in transmission properties. Always perform a range check after: installing, modifying or rearranging components in the model, ...
Page 50
Transmitter Procedure If the model is fitted with a power system, switch it off! Press and hold the ¡ button on the transmitter as you switch the transmitter on. Switch on the receiver. 4. In the Servo > Test run menu, activate the test run for a control function, e.g.
Page 51
Transmitter For "spread spectrum", every data bit is coded in 64 bits (spread). This procedure provides a high level of interference resistance. During binding, the transmitter passes "hopping sequence“, "spreading code", and "response time" to the receiver. Procedure Press and hold the tool button and switch the transmitter on. Once activated, the safety check display is shown.
M-LINK to the teacher transmitter (without trim and travel settings). PROFI TX A second with COPILOT module or another MULTIPLEX transmitter with trainer stick can be used as the teacher transmitter. Refer to "Training" on page 96 for details. Teacher mode A free switch on the teacher transmitter and the COPILOT module are required for the Teacher mode (see section 10.2 "Accessories"...
Transmitter Digital trim 3.8.1 Overview "Trimming" refers to the adjustment of the model aircraft to fly straight and level when you leave the sticks exactly at centre. Digital trim has two essential advantages: The physical position of a conventional trim with trim slider corresponds to the actual trim value, while digital trim buttons do not.
Transmitter about 0.8 sec., the trim value changes continuously until you release the button again (AUTO-REPEAT function). When the trim reaches centre, the AUTO- REPEAT function stops briefly. Each trim increment is accompanied by an acoustic signal. On reaching the trim centre and on reaching the maximum trim range, specific acoustic signals are emitted to alert the user.

Menus Travel Setting for the control travel (flight phase specific): 0% to 100% You can influence the control sensitivity of a control during a specific flight phase using the Travel parameter. That means you can configure a different value for each flight phase, e.g. in the flight phase NORMAL = 100% for maximum control surface effectiveness, in the flight phase SPEED1 = 60% for finer control.

The throttle curve is used. Individual curves are used for each flight phase.
Menus Trim Display of the throttle trim value Lower limit Defines the lower limit for the throttle curve to ensure safe idle speed. This setting is overridden in the auto-rotation flight phase (AUTOROT). Not required for models with electric power system: Thus, set to 0%. The flight phase-dependent throttle trim is added to the lower limit and thus increases the lower limit by the trim value.

Menus Special case: auto-rotation In the AUTOROT flight phase the throttle curve is switched off. All curve points have the same value: You can set the throttle position for auto-rotation at every curve point. The lower limit is switched off.

Glossary of technical terms Differential Indicates the percentage by which the travel distance of the control surface down is reduced relative to the travel distance up; if the differential is set to 50%, the travel distance down is half as great as the travel distance up. The higher the % value, the shorter the travel distance of the control surface down.
Page 219
