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.
