HoTT system gives user real-time information on various useful data such as user model‟s RPM, voltage, temperature, user programmable warning, 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 SJ INCORPORATED. For up-to-date product literature, visit http://www.openhobby.com and click on the support tab for this product WARNING: 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. FLYING SAFETY • Do not fly your model near spectators, parking areas or any other area that could result in injury to people or damage of property. • Ensure that all channels are working in the proper manner. • Perform a ground range check prior to the initial flight of the day • Do not fly during adverse weather conditions. Poor visibility can cause disorientation and loss of control of your aircraft. Strong winds can cause similar problems • We strongly recommend to set the Failsafe function and also recommend that the preset Failsafe would be idle position • You need to set the function of the transmitter after removing a power battery from a model or stopping a engine of a model. • Ensure that all your batteries have been properly charged prior to flight. GENERAL INFORMATION 1. Products • GR-12L : Normal Rx 6ch 2. Features • The use of up to 75 channels ensures extreme operating reliability and immunity to external interference. • High bright LED allows to check the operating status • The optimized sizes and weights • Receiver input sensitivity and thus the range have been increased further. • Servo connections in the front panel. • Failsafe, Hold, OFF, and standard (channel 1 failsafe; all others hold) programmable. 3. The Specification When turning on or adjusting the radio control system it is essential to keep transmitter antenna at least 30 cm away from receiver antenna all the time. If transmitter antenna is too close to receiver antenna, receiver will be overloaded and the red status LED on receiver blinks red. 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 transmitter is ceased and the red status LED on the receiver turns off 4. LED indicator You may check the signal reception according to status LED • LED off : Very good reception • LED blinking : Poor reception • LED on : No signal reception OPERATION 1. Binding • GR-12L Turn on receiver‟s power and press Bind button on receiver for 3 seconds, the red status LED turns off. Follow the procedures of your specific transmitter to bind, the system will connect within a few seconds. NOTICE: Once transmitter and receiver are connected, the red status LED on the receiver is off, 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 receiver must be bound to the transmitter individually according to the procedure already described. The last bound receiver is the master receiver when the system is in use. Every telemetry sensors installed in the model must be connected to the master receiver, since the only master receiver transmits the sensor data through the downlink channel. The second and all further receivers are operated as the slave mode which are connected in parallel to the master …
