2.7.1 FUNCTIONS menu description
RCV NOTIFY: The raw NAVTEX signal can be monitored through the monitor speaker by turning
RCV NOTIFY on. The default setting is OFF.
RCV ALARM: The audible alarm may be generated when message type A, B, D or L is received.
The default setting is ON.
KEY BEEP: The equipment can emit a beep tone when a control is operated. The default setting
is ON.
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%.
