INTRODUCTION The following instructions are for replacing the antenna in a DX8. Read them com- pletely before beginning to replace your antenna. Items Needed: • New antenna assembly (SPM6831) • Medium Phillips head screwdriver CAUTION: Never turn the radio on when the antenna is not attached to the module. Powering up the transmitter without the antenna attached can damage the transmitter. STEP 1 With the transmitter power switch in the “Off” position, remove the battery from the battery compartment. STEP 2 Place the radio face down on a cushioned surface to protect it from being damaged. Remove the two back rubber grips. STEP 3 Beginning at a corner, carefully peel the back edge of the 2 side grips away from the radio back. Once you have exposed the case seam line, leave the remaining portion of the side grips on the front case half. STEP 4 Using a Phillips screw driver, remove the 6 screws holding the transmitter case together. All removed screws should be placed in a designated area where they will not be lost and should be placed in a manner that will allow for ordered reinsertion. STEP 5 Carefully remove the back case half and lay it aside. Use care not to pull on the wire harness plugged into the encoder board in the front case half. If desired, you can disconnect the back case wire harness connector from the encoder board in the front case.

up while wiggling slightly. The antenna should disconnect easily. STEP 7 Remove the two screws holding the RF deck in place with a Phillips head screw- driver and then remove the RF deck observing the alignment of the pins so it can be reinserted correctly later. STEP 8 Remove the screw which connects the slotted metal base plate to the antenna mount using a Phillips screwdriver. STEP 9 Slide the slotted antenna base off of the antenna wire. STEP 10 Gently pull the antenna wire tight and parallel to the antenna mount while pulling up on the antenna housing allowing the antenna assembly to slide out of the transmitter. STEP 11 Install the new antenna assembly in the transmitter. Feed the antenna wire through the rectangular slot in the metal base plate. Make sure the key at the base of the antenna mount is in the non-rectangular slot. Use care not to pinch the antenna wire. Fasten it in place using the Phillips screw. STEP 12 Reinsert the RF deck paying attention to the proper pin alignment. Fasten the two screws which secure the RF deck. STEP 13 Grab the antenna wire near the wires’ coaxial connector with one hand. With the other hand, place the coaxial connector over the connection point on the RF board (making sure they are properly aligned) and use your thumb or a flat screwdriver to press the coaxial onto the connection point. (If using a screwdriver be careful not to damage any board components.) If connected properly, the wire should swivel slightly without disconnecting. STEP 14 Confirm the installation was done correctly by checking that all wires, screws and other components are back to their original position with the new antenna installed. Check to ensure no wires are kinked or will be pinched when the transmitter is screwed back together. Reassemble the unit, replace battery and perform a range check. Range check procedures: 1. With the model resting on the ground, system powered and model secured, stand 30 paces (approx. 90 feet) away from the model. 2. Face the model with the transmitter in your normal flying position and place the radio in range test mode as described in the instruction manual. Press and hold the Trainer Button to activate Range Test mode. 3. You should have total control of the model at 30 paces (90 feet). 4. If control issues exist, contact the appropriate Horizon Product Support Department for further assistance. Note: If any time during or after the installation you do not feel confident- about the installation, please send the replacement antenna and transmit- ter to the appropriate Horizon Service Center where this procedure can be performed by an authorized service technician. WARNING: ENSURE FUTURE ANTENNA SAFETY - Do not attempt to use the antenna to bear any weight, pick up the transmitter by the antenna or alter the antenna in any way. If the transmitter antenna or related components become damaged the output strength can be severely impeded which will likely lead to a crash, injury, and property damage.
