Narrative:
While approaching the terminal area we wondered why we hadn't been descended to lower altitude. We tried to call ATC but there was no response, so we called local approach frequency. Controller said that they had been looking for us on the frequency. Our radios feature a system whereby one pilot may bring the frequencys from the cross side radio up on their radio tuning CRT (called the rmu -- radio management unit). The captain, while calling company with in range call had used the cross side switching or at least thought he had. He actually tuned company on radio #1, while thinking he was tuning them on #2. Thus we were tuned to company on both radios and ATC was not up at all. This system is provided as a method to prevent pilots from hitting thrust levers while tuning cross side radios. However, attention must be paid while using the feature.

Title: FLC OF AN EMBRAER EM145 (E145), FAILED TO MAINTAIN 2-WAY RADIO COM WITH ATC DURING TERMINAL ARR RESULTING IN MISSED CALLS FROM ATC.
Narrative: WHILE APCHING THE TERMINAL AREA WE WONDERED WHY WE HADN'T BEEN DSNDED TO LOWER ALT. WE TRIED TO CALL ATC BUT THERE WAS NO RESPONSE, SO WE CALLED LCL APCH FREQ. CTLR SAID THAT THEY HAD BEEN LOOKING FOR US ON THE FREQ. OUR RADIOS FEATURE A SYS WHEREBY ONE PLT MAY BRING THE FREQS FROM THE CROSS SIDE RADIO UP ON THEIR RADIO TUNING CRT (CALLED THE RMU -- RADIO MGMNT UNIT). THE CAPT, WHILE CALLING COMPANY WITH IN RANGE CALL HAD USED THE CROSS SIDE SWITCHING OR AT LEAST THOUGHT HE HAD. HE ACTUALLY TUNED COMPANY ON RADIO #1, WHILE THINKING HE WAS TUNING THEM ON #2. THUS WE WERE TUNED TO COMPANY ON BOTH RADIOS AND ATC WAS NOT UP AT ALL. THIS SYS IS PROVIDED AS A METHOD TO PREVENT PLTS FROM HITTING THRUST LEVERS WHILE TUNING CROSS SIDE RADIOS. HOWEVER, ATTN MUST BE PAID WHILE USING THE FEATURE.
