Taking into account a range of parameters determined from the evolutionarymodels and available observational data, the detailed non-LTE spectra for theprimary star and the irradiated donor star in the only known eclipsing AM CVnsystem to date SDSS J0926+3624 are constructed based on the TLUSTY stellaratmosphere code. The combined spectrum of the primary and the donor stars alongwith a multi-color blackbody spectrum of the accretion disk that reproduces adetailed numerical model is compared to the SDSS optical spectrum of thesystem. The photometric flux of the primary star inferred from eclipseobservations is compared with the synthetic spectrum. The model fit of the twoindependent observations provides an upper limit on the distance of the systemfor different effective temperatures of the primary. In addition, an upperlimit on the combined flux of the disk and the donor in the infrared regionwherein the contribution of the primary is negligible is also determined. It isshown that the spectrum of a sufficiently cool donor can exhibit emission linesdue to irradiation from a hot primary and the emission features should bedetectable in the infrared even though the contribution of the flux from thedisk dominates. Thus, it is pointed out that infrared observations of thesystem would provide important information on the thermal state of the donor aswell as useful insight on the thermal properties of the primary star and theaccretion disk.
