Adjustable bed control box replacement: what to verify
Knowing which handset belongs to a control box is useful, but it does not prove that another control box can replace it.
Source-linked records · reviewed dataset 1.0.0 · September 2026
Identify the component before reading its label
Keep the control-box label separate from the power supply and base-frame labels. Copy the complete model, suffix, and any documented PCBA or program field. Follow the bed manufacturer’s access instructions; do not open electrical enclosures to use this Finder.
Know what a system-pair result means
MC120NM has a documented RF399B remote pair. That is a box-to-handset relationship, not an MC120NM replacement box. The same distinction applies to the qualified Kaidi sample configurations below.
Ask for the original-to-replacement evidence
For a box substitution, the source must identify your original box and the proposed replacement, with applicable conditions. The current dataset has no approved conversion-kit bill of materials. A kit title or matching connector shape is insufficient.
Keep programs attached to their own components
In one Kaidi sample, the box program is 1760 and the handset program is 1761. These are distinct fields, not interchangeable settings. Missing configuration information keeps the result Unknown.
What we verified
Source-specific evidence
Read each row from original to target. A base application or box-to-remote pair is not a remote-to-remote replacement. Known constraints remain part of the decision.
Documented relationships; direction and exact scope matter
The manufacturer sample specification explicitly pairs these PCBA/program configurations. Confirm all identifiers; a generic family match does not satisfy this documented system scope.
Keeson RF399B manual explicitly names matching model MC120NM. This is a documented system pair, not substitution for another box or firmware. Feature preservation on other systems is unknown.
The sample specification distinguishes PCBA KD3143 and program 1760. Do not infer matching firmware from the housing or family name.

RF399B manufacturer manual names matching control model MC120NM and receiver FCC ID 2AK23MC120NM. This is not a family-wide MC120 compatibility assertion.
