To ensure safe operation, always perform a range test and functional test on the ground before you use your model! Maintain frequent updates of your HoTT components with the latest firmware version. Always use matching, original Graupner plug-in connections of the same design and material. Make sure that all of the plug-in connections are tight. When disconnecting the plug-in connections, do not pull the cables. For additional questions or support, contact the Graupner USA Service Center, or an experienced user. WARNING! Safety notes during the use Rotating propellers can be dangerous. Never touch the turning propellers. This can cause serious injury. To make sure the connected motors cannot accidentally start when programming the transmitter, turn the transmitter s motor off, or detach the propellers. To avoid electrical shock, check the mz-4 HoTT regularly for damages to the housings and cables, especially after a model crashes. Discontinue using any electronic components that have become wet; short-circuiting and shock risk is still prevalent even after components have dried. The propellers must be mounted securely; thrown parts can cause serious injury. Keep long hair, loose clothing such as scarves, loose shirts, etc., away from the propeller. Damage to the propellers may occur and flying debris may cause serious injury. Observe the safety notes of the required components. Note Carefully pack the model and transmitter when transporting to protect from damages and excessive vibration. 7 / 16

Transmitter Power Supply Installing transmitter batteries Remove the battery case cover on the back of the transmitter. Insert the battery according to the correct polarity. (See figure in the battery case) Removing transmitter batteries If the transmitter is not going to be used for an extended period of time, remove the batteries/accumulators from the device. Batteries stored long-term risk leaking or corrosion. Preparation before use The mz-4 HoTT transmitter comes with three AAA alkaline batteries. The transmitter battery voltage is monitored by the red LED 2 light during operation. If voltage drops below 3.5 V, an acoustic alarm (4x beeps) will sound and the LED 2 red light will blink. Immediately discontinue using the transmitter and replace batteries. Binding the Receiver To bind a receiver with the mz-4 HoTT transmitter, place the receiver in bind mode and/or attach receiver to power supply. Stand at least 1 meter (3 feet) away from receiver. Press and hold the CUT OFF/BIND button on the transmitter. Bind is successful when the red LED 2 light stays on. If another receiver is already bound to the model memory, clear the memory before binding the new receiver. To clear the memory, follow the binding instructions twice. The first process erases the previous receiver, the second process binds the new receiver. Binding the Vector Unit GRS 331 1. Attach the Vector Unit to the power supply. 2. Stand at least 1 meter away from receiver. 3. Press and hold the CUT OFF/ BIND button on the transmitter. Successful binding process The transmitter s red LED 2 light is on.
