New observations and theoretical models for the continuous UV-to-radio spectrum of the ultraluminous protogalaxy candidate IRAS F10214 + 4724 are presented. The radio spectrum at 1.49-8.44 GHz and the resolved nature of the radio source are compatible with a synchrotron origin of the radio radiation associated with a luminous starburst. The submillimeter and FIR spectrum is modeled in terms of emission from both spherically symmetric dust clouds and an axially symmetric flared disk. The observed optical to near-IR continuum derived from WHT-FOS spectroscopy and from UKIRT observations is interpreted in terms of reddened QSO and starburst models. The continuum is broadly consistent with emission from a QSO reddened by 1.5 mag of dust. The radio, submillimeter, FIR, and CO observations of IRAS F10214 + 4724 are consistent with a powerful starburst early in the life of a massive galaxy.
