Safety Information

Radio-controlled models commonly contain sharp components like propellers, rotating at high RPM; when operating or maintaining the model, always use common sense and proceed with caution. Always disconnect power to the model AND remove propellers (if applicable) during the assembly or maintenance process.

Never operate the POCKET radio system in 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

POCKET is pre-installed with the most stable firmware at the factory at time of release. Please only attempt to update the firmware if you are confident in the process. Incorrect firmware updates may cause the remote control to become inoperable.

Batteries & Charging

POCKET is powered by (2x) 3.7V 18650 Lithium Ion cells and is charged using the built-in USB-C port. The charging circuitry is designed for charging (2x) 3.7V Lithium Ion batteries only. The nominal voltage is 3.7V and the maximum charging voltage is 4.2V.

DO NOT charge 3.6V LiFe and 3.6V 18650 Lithium Ion packs with the onboard charger. Charging or using the wrong battery chemistry/polarity may cause permanent damage to the PCB and in certain situations cause fires.

Please check the voltage and condition of the battery regularly and never charge unattended. Always charge in a safe area away from combustible materials. Refrain from charging if the remote control gets wet or damaged in any way. DO NOT charge with the polarity reversed.

RadioMaster does not assume any responsibility for any adverse consequences caused by the use or misuse of this product.

Setup Process: Long press the MDL button to enter model settings. Select MULTI in the SETUP page and choose the desired protocol in the sub-options. The system will automatically activate the corresponding RF module.

Bind [BND]: Used to start the binding process.

Range [RNG]: Reduces power to 1/30 for remote-control distance testing.

Attention: CC2500 users may need frequency tuning. Refer to: www.multi-module.org/using-the-module/frequency-tuning

ELRS Version

POCKET ELRS units have an internal ELRS module. For optimal performance, enable Dynamic Power and use a 500Hz or lower packet rate to extend battery life and minimize heat generation.

Bind Instructions (ELRS Version)

Follow these steps to bind your ELRS receiver:

1. Turn OFF the transmitter.
2. Cycle power to the receiver 3 times; the receiver LED will flash twice, indicating bind mode.
3. Turn ON the transmitter, long press the SYS button, navigate to TOOLS, select ExpressLRS LUA, scroll to [Bind], and press Enter.
4. The receiver LED should now be solid, indicating a successful bind.
