2. Key Features

• Advanced Anti-Interference: Utilizes DSSS and FHSS communication technology with a 7dBi high-gain antenna for stable signal transmission and a control range of up to 2.5 miles (4 km) in open air.
• Real-time Telemetry: Monitors aircraft voltage on the AT10II screen when combined with the PRM-01 module (included). With the PRM-03 module (sold separately) and compatible flight controllers (Crossflight, APM, Pixhawk, Mini Pix), it provides telemetry data such as battery voltage, speed, altitude, RSSI, and distance.
• Comprehensive Functionality: Features 20mW power, 12 channels, battery voltage telemetry, RSSI telemetry, dual/triple rates, throttle lock, failsafe configuration, End Point Adjustment (EPA), customizable switches, and channel mix control.
• Wide Receiver Compatibility: Compatible with Radiolink R12DS, R12DSM, R9DS, R6DS, and R6DSM receivers.
• Model Memory: Stores up to 15 models, allowing quick switching between helicopter, quadcopter, fixed-wing, glider, car, BoxBot, and boat configurations.
• User-Friendly Interface: Supports both basic and advanced menus for diverse user needs, with an intuitive and easy-to-navigate user interface. No complex radio configuration is required for binding.
• Safety Alerts: Includes RSSI indicator alerts, low voltage alarms, and failsafe protection. Audible and visual (DD alarm words on the 3.5" LCD) reminders are provided for critical conditions.
• Customizable Controls: Equipped with 3 VR switches, 3 three-way switches, 4 two-way switches, and 1 trainer reset switch. All 12 channels can be assigned to any switch.

4.2. Channel Configuration for Receivers

When using different receivers (e.g., 10-channel vs. 12-channel), it is crucial to adjust the transmitter's channel setting to match the receiver. Failure to do so may result in unstable servo operation or loss of control.

This video illustrates the process of changing the channel selection on the AT9S Pro transmitter to ensure proper functionality with both 10-channel and 12-channel receivers.

5. Operating Instructions

5.1. Throttle Configuration

The AT10II supports changing the throttle stick from left to right, or setting it to dual-stick back to center. This allows users to configure the transmitter according to their preferred mode (Mode 1 or Mode 2).
