2. FLYING SAFETY

Read the ENTIRE instruction manual to become familiar with the features of the
product before operating. Failure to operate the product correctly can result in
damage to the product, personal property and cause serious injury.

WARNING

Graupner HoTT receivers are compatible with all of Graupner transmitters and used to

airplane, helicopter and glider. HoTT system gives user real-time information on various

useful data such as user model’s RPM, voltage, temperature, user programmable warn

-

ing, and so on which are directly obtained from telemetric speed controllers equipped

with this HoTT system without having to install separate sensor devices. Of course, all of

those telemetric data can be also transmitted from separate sensor devices. The use of
up to 75 hopping channels provides advanced reliable operation while keeping from any
external interference.
All instructions, warranties and other collateral documents are subject to change at the

sole discretion of Graupner. For up-to-date product literature, visit http://www.openhob

1. Do not y your model near spectators, parking areas or any other area that could
result in injury to people or damage of property.

2. Ensure that all channels are working in the proper manner.

3. Perform a ground range check prior to the initial ight of the day

model or stopping a engine of a model.

7. Ensure that all your batteries have been properly charged prior to ight.

- The use of up to 75 channels ensures extreme operating reliability and immunity to
external interference.

- The broad reception voltage range of 3.6 V - 8.4 V (functional to 2.5 V) ensures full
func tionality even when voltage uctuates.

- Two LEDs signal operating status.

- The optimized sizes and weights

- Receiver input sensitivity and thus the range have been increased further.

- Servo connections in the front panel.

- SPECIFICATION

When switching on or adjusting the radio control system it is essential to keep the

transmitter antenna at least 30 cm away from the receiver antenna all the time. If

the transmitter antenna is too close to the receiver antenna, the receiver will be
overloaded and the status LED on the receiver blinks red. The transmitter
responds by repeating a single beep every second and the radio control system is
entered Fail-Safe mode. If the distance of the antennas between transmitter and
receiver would be simply longer than 30cm in this situation, the beep of transmit

-

ter is ceased and the status LED on the receiver turns solid green

1) Binding

- Switch on the transmitter and receiver. The status LED of the receiver blinks red until

the receiver is bound to the transmitter.

- Enter BIND mode of your specic transmitter and press & hold the SET button on the

receiver for over 3 sec, the red status LED and the green status LED blink together.
After that, follow the procedures of your specic transmitter to bind, the system will

connect within a few seconds. Once connected, the status LED on the receiver turns

solid green, indicating the receiver is bound to the transmitter. If the binding process

has failed, repeat the whole procedure.

- Binding a number of receivers in one model

It is possible to bind a number of receivers to a transmitter in one model. Every receiv-

er must be bound to the transmitter individually according to the procedure already
described.
