900 MHz intercom Frequency?

[marksroberson]

I have a Radio Shack 43-124 900Mhz intercom system and was wondering if anyone knew the specific frequency of these intercoms, the FCC ID is AAO430124 if that helps, its probably in the ISM bands

This is where I looked it up.
OET -- FCC ID Search

According to the test results from the FCC Type Certification it shows:
910MHz
911MHz
912MHz
913MHz
