SYNTAX had heard that 2050 MODEMs stopped at high temperatures, but the manufacturer says this problem no longer exists. Westridge, the maker, points out that the failures at 160 F ambient were above the rated range anyway. Nonetheless, a resistor change raised the temperature at which errors occur 40 F above the rated operating temperature. With this change, you can run at 110 F!
