The Steris Amsco 3080 RL/SP and 3085 SP hand control (P/N BF336) is a lightweight, fluid‑tight remote console that drives table articulation via pushbuttons and an integrated return‑to‑level function. Common failure points for this class of surgical table controls include worn button contacts, degraded seal integrity leading to moisture ingress, and loss of communication with the table’s internal controller due to faulty wiring or connector corrosion. First‑check diagnostics: verify 12 V DC power at the control housing, inspect all pushbutton terminals for continuity and mechanical wear, and review any diagnostic LEDs or error codes displayed on the unit; if none are present, perform a visual inspection of the cable harness for fraying or broken insulation before proceeding to internal component testing.[oss-gpt-20b]
