The ATARI 830 Modem is acoustically coupled. Both input and output signals are transformed into tones in the audible range. Consppuently, the modem may respond to extraneous sounds in the environment. The rubber muffs on the modem attenuate environmental sounds, but loud sounds or nearby percussive effect (such as tapping the table) are quite likely to be received and/or transmitted as (false) signals. You should place the modem in a location to minimize unintended effects of this nature.
