Conformity declaration / Guarantee / Manufacturer’s declaration / Disposal..17 Manual V1.0 Revision: Januar 2013 MANY THANKS for deciding to purchase the Graupner/SJ HoTT 2.4 system. Please read right through these operating instructions before you attempt to install and operate the Graupner HoTT 2.4 system. • The receiver stabilises the model aircraft in difficult, windy conditions, acting on a maximum of three axes • Proportional gyro suppression for natural flying characteristics • Excellent stabilisation for smooth, accurate manoeuvres • The triple-axis gyro endows even very demanding aerobatic models with docile flying characteristics, and greatly simplifies aerobatics • Aerobatic manoeuvres can be flown much more accurately • Simple gyro assignment procedure • Facility to adjust parameters using HoTT telemetry • Altitude sensor for vario and altimeter function (Order No. 33577) 1. APPROVED USAGE The receiver is intended exclusively for use in radio-controlled models. Any other usage is prohibited, and may result in damage to the receiver or model, and serious personal injury. We grant no guarantee and accept no liability for any type of use outside the stipulated range. Not suitable for children under fourteen years. This receiver is not a toy! The receiver is also equipped with a telemetry function which is only available in combination with a Graupner/SJ HoTT 2.4 system. If you do not own a Graupner/SJ HoTT 2.4 system, the receiver will not work. Please start by reading through the whole instructions before you attempt to install and operate the receiver. These operating instructions are an integral part of the product. They contain important notes on operating and handling the receiver. For this reason please store the operating instructions in a safe place, and pass them on to the new owner if you ever dispose of the product. Failure to observe the operating instructions and safety notes invalidates the guarantee. Here at Graupner we are constantly working on the further development of all our products; for this reason we are obliged to reserve the right to introduce changes to the set contents in form, technology and features. Please understand that we will not countenance claims resulting from information and illustrations in these operating instructions. Please store the operating instructions in a safe place for future reference! 1.1 SAFETY NOTES KEY TO THE SYMBOLS Caution!
