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.
Sources included · Dataset 1.0.0 reviewed September 2026
Make sure you’re reading the control-box 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.
A remote match isn’t a replacement box
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 evidence that names both boxes
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.
Detailed relationship records and source claims
What the sources confirm
Source-specific evidence
Read each match in the direction shown and check its conditions. A listed base or control-box match tells you which remote it uses; it doesn’t name a replacement for another remote.
Documented matches: check the direction and conditions
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.
Evidence dates describe the reviewed records. They are not a promise of continuous monitoring. Read the verification method.

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.
