9. derstand that during the binding process the receiver not only learns the GUID code of the transmitter but the transmitter learns and stores the type of receiver that it s bound to If the transmitter is placed into bind mode the transmitter looks for the binding protocol signal from a receiver If no signal is present the transmitter no longer has the correct information to connect to a specific receiver and in essence the transmitter has been unbound from the receiver We ve had several DX7 customers that use transmitter stands or trays that unknowingly depress the bind button and the system is then turned on losing the necessary information to allow the connection to take place We ve also had DX7 customers that didn t fully understand the range test process and pushed the bind button before turning on the transmitter also causing the system to lose its bind Warranty Period Exclusive Warranty Horizon Hobby Inc Horizon warranties that the Products purchased the Product will be free from defects in materials and workmanship for a period of 1 year from the date of purchase by the Purchaser Limited Warranty a This warranty is limited to the original Purchaser Purchaser and is not transferable REPAIR OR REPLACEMENT AS PROVIDED UNDER THIS WARRANTY IS THE EXCLUSIVE REMEDY OF THE PURCHASER This warranty covers only those Products purchased from an authorized Horizon dealer Third party transactions ar

14. licopters ModelMatch Some Spektrum and JR transmitters offer a patent pending feature called ModelMatch ModelMatch prevents the possibility of operating a model using the wrong model memory potentially preventing a crash With ModelMatch each model memory has its own unique code GUID and during the binding process the code is programmed into the receiver Later when the system is turned on the receiver will only connect to the transmitter if the corresponding model memory is programmed on screen Note If at any time you turn on the system and it fails to connect check to be sure the correct model memory is selected in the transmitter Please note that the Spektrum Aircraft Modules do not have ModelMatch Tips on Using Spektrum 2 4GHz While your DSM equipped 2 4GHz system is intuitive to operate functioning nearly identically to 72MHz systems following are a few common questions from customers Q Which do I turn on first the transmitter or the receiver A If the receiver is turned off first all servos except for the throttle will be driven to their preset failsafe positions set during binding At this time the throttle channel doesn t output a pulse position preventing the arming of electronic speed controllers or in the case of an engine powered aircraft the throttle servo remaining in its current position When the transmitter is then turned on the transmitter scans the 2 4GHz band and acquires two open channels Then the re
