How to set the safe values for Easy Routing
Follow the procedure below to set the safe values to use in Easy Routing.
1. Open the [PLOTTER] menu and select [EASY ROUTING].
2. [SAFE DEPTH] is the minimum safe depth, namely, your vessel's draft. The set-
ting range is 3.3 to 65.6 (ft).
3. [SAFE HEIGHT] is the minimum safe height, namely, the height of your vessel.
The setting range is 6.6 to 164.1 (ft).
4. [SAFE CORRIDOR] is the minimum width of the path. The setting range is 0.0011
to 0.0099 (NM).
5. [TIMEOUT] is the amount of time to wait before exiting the Easy Routing function,
when it cannot create a route. The setting range is 1 to 20 (min.).
6. [SAFE MARGIN] is the minimum distance (300 m) between a dangerous/not nav-
igable area and the vessel. This area could be land or a body of water. Turn it on
to honor this distance.
7. Turn on [RESPECT DRAUGHT] if you want to disregard the depths that are shal-
lower than the [SAFE DEPTH] setting.
