Disturbances of the Operating Voltage
The range of the operating voltage in which the modem functions safely is from 16.6 up to 26.4V
DC. If the operating voltage falls below the limit, a RESET is released in the modem that is
maintained until the operating voltage is restored. This ensures that malfunctions due to too low
operating voltages are excluded. In this case and if the operating voltage breaks down entirely
the modem hangs up. Data transmission has to be repeated after returning to the operating
state.
