3. Setup

3.1 Battery Installation

1. Locate the battery compartment cover on the back of the transmitter (refer to Figure 2.4).
2. Slide or unclip the cover to open the compartment.
3. Insert the required batteries (e.g., AA batteries, typically 4x) according to the polarity indicators (+/-) inside the compartment.
4. Close the battery compartment cover securely.

3.2 Binding the Receiver (if applicable)

If your package includes a receiver or you are using a new receiver, it must be bound to the transmitter before use. Refer to your receiver's specific manual for detailed binding instructions, as procedures can vary. Generally, the process involves putting both the transmitter and receiver into binding mode, often by pressing a bind button on the receiver while powering it on, and then powering on the transmitter.

4. Operating Instructions

4.1 Powering On/Off

• To power on: Press and hold the power button until the power indicator lights up.
• To power off: Press and hold the power button until the power indicator turns off.

4.2 Control Modes (Mode 1 vs. Mode 2)

The HT-8A transmitter is available in different control modes, primarily Mode 1 and Mode 2. The specific unit you have is "Mode2 only TX".

Figure 4.1: The HT-8A transmitter configured for Mode 2, indicating the left-hand stick controls throttle and rudder.

• Mode 2 (Left Hand Throttle):
  • Left Stick: Vertical movement controls Throttle (power), Horizontal movement controls Rudder (yaw).
  • Right Stick: Vertical movement controls Elevator (pitch), Horizontal movement controls Aileron (roll).
• Note: If you have a Mode 1 transmitter, the throttle and elevator controls are typically swapped between the left and right sticks.

4.3 Using Switches and Trims

• Trims: Small buttons or sliders adjacent to the main control sticks. Use these to make fine adjustments to the neutral position of your control surfaces (e.g., to make an aircraft fly straight without constant stick input).
• Switches: The various switches (5-aisle, 6-aisle, 8-aisle, D/R) can be assigned to control different functions on your model, such as landing gear, flaps, flight modes, or dual rates (D/R) which adjust the sensitivity of controls. Refer to your model's manual for specific channel assignments.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the transmitter. Avoid using harsh chemicals or abrasive materials.
• Storage: Store the transmitter in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods to prevent leakage.
• Inspection: Periodically check for any loose connections, damaged wires, or physical damage.
