Raymarine H6 - Owner’s Manual
In Auto mode, the radar tunes itself automatically on all range scales. If you
decide to use manual fine-tuning, adjust it about 10 minutes after you have
turned the radar on to allow the magnetron to warm up. The optimum setting
varies slightly for different display ranges, depending on the pulse width used.
Note:
It is recommended that you leave the tune function in AUTO mode, to ensure that
the radar receiver is always tuned to receive the maximum signal.
Making a target clearer
You can improve a target’s visibility using the Target function controls.
To use the target controls:
1. Click on the softkey for the required function.
2. Click on the softkey for control options.
3. Adjust the settings as necessary.
4. When you have finished, click the
BACK button.
Interference rejection
The interference rejection (Int rej) function reduces the interference caused by
radar equipped boats operating within range of each other.
Expansion
The target expansion function makes targets easier to see by expanding them.
The radar scanner type determines the range at which target expansion is
available. Target expansion overrides the normal pulse length, thereby increasing
the size of the target seen on the screen; however, this is at the expense of range
resolution.
Wakes
The wakes function enables you to see the direction and speed with which targets
are moving relative to your boat.
With wakes switched on, a target is displayed at the brightest level, while its
previous positions are retained at successively fainter levels on the screen. You
can select long, medium or short wakes, all of which retain information from
previous scans at a reduced video level.
