Communications
This section explains general troubleshooting procedures for the 400 series of Information Codes. These errors are primarily
caused by poor telephone line quality (loss, noise, echo, etc.). This unit is furnished with Service Mode 1 to assist in troubleshooting
line quality problems.
It is suggested that both the transmitting unit and receiving unit be adjusted. This section gives relevant parameters in Service
Mode 1 for the transmitting and receiving sides. If no improvement is realized after the parameters are adjusted, it is recommended
that the parameters be returned to the default settings.
