ERROR RATE: When character error occurs due to noise interference during signal propagation,
erroneous character is displayed as “∗”.
Error Rate means character error rate and is calculated as followed:
Error Rate = number of erroneous characters ÷ total number of characters received × 100 (%)
(Total number of characters includes space, line feed, carriage returns, etc.)
When the character error rate is within the percentage you set (0-39%), the NX-300 displays the
message and stores it. When it exceeds the percentage you set, the NX-300 neither displays nor
stores the message. You may set the threshold level of character error rate as desired and the
default setting is 33%.
