STEP 6
Remove the screw which connects the slotted metal base plate to the antenna
mount using a Phillips screwdriver.
STEP 7
Slide the slotted antenna base off of the antenna wire.
STEP 8
Slide the antenna assembly out of the top of the transmitter.
STEP 9
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 10
Grasp the antenna wire near the wires’ coaxial connector and align it over
the connector on the RF board. Using your other hand or a screwdriver, press
the antenna’s coaxial connector onto the RF board’s connector. (If using a
screwdriver be careful not to damage any board components.) If connected
properly, the wire should swivel slightly without disconnecting.
STEP 11
Reconnect the wires from the case back to the proper connector on the encoder
board in the front case. 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,
reinstall the batteries and battery door 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 check mode as described in the instruction manual.
3. You should have total control of the model while in the range check mode.
4. If control issues exist, contact the appropriate Horizon Product Support of-
fice 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 transmitter 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.
