Radiomaster Pocket Hall Gimbal Transmitter User Manual

1. Introduction

Thank you for purchasing the Radiomaster POCKET radio system. This advanced and highly versatile transmitter is designed for pilots of all skill levels. To ensure safe and reliable operation, please read this manual thoroughly before use.

The information in this manual is subject to change without prior notice as software and hardware are continuously improved. For the most up-to-date information and radio firmware, please visit the official Radiomaster website.

The POCKET is an open-source, ergonomic radio with powerful multi-protocol capabilities, allowing it to bind with most contemporary protocols. It runs on EdgeTX, an open-source operating system. For more information on EdgeTX, visit www.edgetx.org.

2. Safety Information

WARNING: Radio-controlled models often contain sharp components like propellers rotating at high RPM. Always use common sense and proceed with caution when operating or maintaining your model. Disconnect power and remove propellers (if applicable) during assembly or maintenance.

Never operate the POCKET radio system under the following conditions:

• In severe weather or strong windy conditions, such as rain, hail, snow, storms, or electromagnetic environments.
• In limited visibility.
• In the proximity of other people, property, high-voltage power lines, public roads, vehicles, or animals.
• When feeling unwell, or under the influence of drugs or alcohol.
• If the POCKET radio system/model is damaged or showing signs of interference.
• In areas with high 2.4GHz interference or where 2.4GHz radios are prohibited.
• When the TX/RX battery is low.
• In areas where local regulations prohibit the use of R/C aircraft.

Important Notes:

• Antenna: Install the provided antenna in the top of the radio BEFORE installing batteries and turning on the radio. DO NOT operate the radio without the antenna installed and the internal RF module powered on. Doing so will damage the internal RF module and will not be covered under warranty.
• Firmware: The POCKET is pre-installed with the most stable firmware at the factory. Only attempt to update the firmware if you are confident in the process. Incorrect firmware updates may cause the remote control to become inoperable.

4. Setup

4.1. Antenna Installation

Before installing batteries and powering on the radio, ensure the antenna is securely installed in the designated port at the top of the transmitter. Operating the radio without the antenna or with the internal RF module powered off can cause damage and void the warranty.

4.2. Battery Installation and Charging

The POCKET is powered by two 3.7V 18650 Lithium-Ion cells (not included). It features a built-in USB-C charging port. The charging circuit is designed exclusively for 3.7V Lithium-Ion batteries. The nominal voltage is 3.7V, and the maximum charging voltage is 4.2V.

CAUTION:

• DO NOT charge 3.6V LiFe and 3.6V 18650 Lithium Ion packs with the onboard charger. Using incorrect battery chemistry/polarity can cause permanent damage to the PCB and may lead to fires.
• Regularly check the battery voltage and condition.
• Always charge in a safe area, away from combustible materials, and never unattended.
• If the remote control gets wet or damaged, do not charge it.
• DO NOT charge with reversed polarity.

4.3. Gimbal Adjustments

The POCKET features adjustable gimbals to customize feel and function:

• L-R (Left-Right Gimbal): To switch between Mode 1/Mode 2, turn clockwise (CW) to disable self-centering, and counter-clockwise (CCW) to enable it.
• T (Throttle Tension): Turn CW to increase throttle stick tension, CCW to decrease.
• C (Up/Down Tension): Turn CW to increase vertical stick tension, CCW to decrease.
• D (Left/Right Tension): Turn CW to increase horizontal stick tension, CCW to decrease.

5. Operation

5.1. Model and Protocol Selection

The POCKET comes with either a CC2500 single-chip multi-protocol module or an internal ELRS module, depending on the version purchased.

• Multi-protocol Module (CC2500): To view the latest list of compatible protocols, visit the multi-module website: www.multi-module.org. New protocols may require firmware upgrades.
• ELRS Version: For optimal performance, enable Dynamic Power and use a 500Hz or lower packet rate to extend battery life and minimize heat generation.

To select a protocol:

1. Long press the MDL button to enter the model settings.
2. Navigate to the SETUP page and select MULTI.
3. Choose the desired protocol from the sub-options. The system will automatically activate the corresponding RF module.

The [BND] option is used to initiate the binding process. The [RNG] button can reduce power to 1/30 for testing remote-control distance.

CC2500 Users: Your receiver may require frequency tuning. Refer to www.multi-module.org/using-the-module/frequency-tuning for tuning instructions before flight.

5.2. Binding Instructions

Follow these steps to bind your POCKET transmitter to a receiver:

1. Turn OFF the transmitter.
2. Cycle power to the receiver 3 times. The receiver's LED will flash twice, indicating bind mode.
3. Turn ON the transmitter. Long press the SYS button and choose ExpressLRS LUA under the TOOLS menu.
4. Scroll to [Bind] and press enter.
5. The LED on the receiver should become solid, indicating a successful bind.

6. Maintenance

To ensure the longevity and optimal performance of your Radiomaster POCKET, follow these maintenance guidelines:

• General Care: Keep the transmitter clean and free from dust and debris. Use a soft, dry cloth for cleaning.
