2.  RADAR, CHART RADAR OPERATION

The watch alert provides a flashing visual alert at regular in-
tervals to remind you to monitor the radar picture for safety or 
other purposes.

To enable the watch alert, open the [8 INITIAL SETTING] 
menu followed by the [4 ALERT] menu. Select [1 WATCH 
ALERT] and set desired watch interval. The [Watch] box ap-
pears at the bottom-left position. (The watch interval can also 
be selected from the [Watch] box when the watch alert fea-
ture is active. Right-click the time indication in the [Watch] box to show a drop-down 
list of watch intervals. Select a watch interval from the list.)

The timer counts down from the interval set and when the time interval elapses;

• the buzzer sounds
•  the visual alert 500 “Watch Alert” flashes in yellow in the [Alert] box
•  the watch alert timer freezes at "0:00." 
Stop the flashing visual alert with the ALARM ACK key on the Control Unit or click the 
[Alert] box. If the alert is not acknowledged within one minute, the alert category 
changes to “warning” (the Alert 500 flashes in red in the [Alert] box and the buzzer 
sounds). 

After the alert is acknowledged the count-down sequence is repeated.

Note: The countdown can be restarted, before the count reaches 0:00, by clicking the 
countdown indication in the watch box.
