This document describes the RF502A remote control for an adjustable bed, specifically the MC120NM model. The remote is manufactured by Keeson Technology Corporation Limited.
Function Description
The RF502A remote control provides comprehensive control over various bed adjustments and features. Its primary function is to allow users to manipulate the bed's position, activate massage functions, and control under-bed lighting.
Bed Positioning:
- ZG Button (11): This button controls the "Zero Gravity" position. A single click moves the bed actuators to the pre-programmed ZG position. The movement stops if any other button is clicked during the process. To set a new ZG position, the user must press and hold the ZG button for 5 seconds. The timer LED on the remote will flash, indicating that the control box has recorded the current bed position as the new ZG position. When moving to memory positions, the head and foot actuators move first, followed by the tilt and lumbar actuators.
- AntiSnore Button (8): Similar to the ZG button, a single click of the AntiSnore button moves the actuators to the AntiSnore position. Movement can be interrupted by clicking any other button. To set a new AntiSnore position, the user presses and holds the AntiSnore button for 5 seconds, causing the timer LED to flash and the control box to record the current position. As with ZG, head and foot actuators move first, then tilt and lumbar actuators, when moving to memory positions.
- Head Up (4): Pressing and holding this button extends the head actuator, raising the head section of the bed. The movement stops when the button is released.
- Head Down (7): Pressing and holding this button retracts the head actuator, lowering the head section of the bed. The movement stops when the button is released.
- Foot Up (6): Pressing and holding this button extends the foot actuator, raising the foot section of the bed. The movement stops when the button is released.
- Foot Down (9): Pressing and holding this button retracts the foot actuator, lowering the foot section of the bed. The movement stops when the button is released. When moving to a flat position, the lumbar actuator and tilt actuator move first, and after 500ms, the head and foot actuators begin moving.
- Flat (13): Clicking this button initiates a sequence that returns the bed to a flat position. The movement can be stopped by clicking any other button during the process.
- Memory Position (10, 12): These buttons allow the user to move the actuators to pre-set memory positions. The specific functionality for setting these memory positions is not detailed but is implied to be similar to ZG and AntiSnore.
Massage Functions:
- Massage Head (1): Clicking this button cycles through the head massage motor's intensity levels (0-1-2-3).
- Massage Foot (3): Clicking this button cycles through the foot massage motor's intensity levels (0-1-2-3).
- Massage Mode (2): Clicking this button switches between different massage modes.
Lighting:
- Under Bed Light (5): Clicking this button toggles the under-bed light on or off. If the light is turned on manually and not turned off, it will automatically switch off after 5 minutes.

Usage Features
The RF502A remote is designed for intuitive and convenient control of an adjustable bed. Key usage features include:
- One-Touch Positioning: Dedicated buttons for "Zero Gravity" and "AntiSnore" positions allow for quick adjustments to preferred comfort settings.
- Customizable Memory Positions: The ability to set and recall custom ZG and AntiSnore positions (by pressing and holding the respective buttons for 5 seconds) provides personalized comfort. The remote's timer LED flashes to confirm the recording of new positions.
- Independent Actuator Control: Separate "Head Up/Down" and "Foot Up/Down" buttons enable independent adjustment of the head and foot sections of the bed, offering granular control over sleeping or lounging positions.
- Massage Intensity and Mode Selection: Users can easily cycle through different massage intensities (0-1-2-3) for both head and foot sections, as well as switch between various massage modes, enhancing relaxation.
- Under-Bed Lighting Control: An integrated under-bed light feature provides ambient lighting, which can be convenient for navigating in the dark. The automatic shut-off after 5 minutes helps conserve energy.
- Flat Position Reset: A dedicated "Flat" button allows for a quick return to a completely flat bed position.
- Interruption Capability: Most bed movements can be stopped at any point by clicking another button, providing immediate control and preventing unintended full-cycle movements.
- Sequential Actuator Movement: When moving to memory or flat positions, the actuators follow a specific sequence (e.g., lumbar and tilt first, then head and foot for flat position), which may contribute to smoother transitions or structural integrity.
Maintenance Features
The document does not explicitly detail maintenance features for the remote control itself, such as battery replacement instructions or cleaning guidelines. However, it provides important regulatory compliance information that implicitly relates to the device's operational integrity and user safety.
Regulatory Compliance:
- FCC Statement: The device complies with Part 15 of the FCC Rules, meaning it operates under specific conditions:
- It may not cause harmful interference.
- It must accept any interference received, including interference that may cause undesired operation.
- Any changes or modifications not expressly approved by the responsible party could void the user's authority to operate the equipment.
- FCC Radiation Exposure Statement: The device has been evaluated and meets general RF exposure requirements, allowing it to be used in portable exposure conditions without restriction.
- FCC Class B Digital Device Note: The equipment has been tested and found to comply with Class B digital device limits, designed to provide reasonable protection against harmful interference in a residential installation. If interference occurs (e.g., with radio or television reception), users are advised to try corrective measures such as reorienting the receiving antenna, increasing separation between equipment and receiver, connecting to a different circuit outlet, or consulting a dealer/technician.
- ISED RSS Warning/ISED RF Exposure Statement: The device complies with Innovation, Science and Economic Development Canada licence-exempt RSS standard(s). Similar to FCC, it must not cause interference and must accept interference, including undesired operation. The device is also evaluated to meet general RF exposure requirements for an uncontrolled environment. The French translation of the ISED statement is also provided, ensuring compliance for French-speaking regions.
These compliance statements ensure that the device is designed and manufactured to operate safely and reliably within specified electromagnetic environments, minimizing the need for user intervention related to interference or exposure issues. The lack of explicit maintenance instructions for the remote suggests it is likely a sealed unit with minimal user-serviceable parts beyond potential battery replacement (though not specified).
