The electronic chart used by the Northstar 8000i is an aid to navigation designed to supplement, not replace, official government charts. Only official government charts supplemented by notices to mariners contain the information required for safe and prudent navigation. Always supplement the electronic information provided by the Northstar 8000i with other plotting sources such as observations, depth soundings, radar and hand compass bearings. Should the information not agree, the discrepancy must be resolved before proceeding any further.
Never operate the 8000i in Simulate Mode while you're underway.
It is the user's responsibility to ensure that Simulate Mode is used only in safe situations such
as when you are moored in a marina.
The accuracy of the sonar depth display can be limited by many factors, including the type of transducer, the location of the transducer, and water conditions. Ensure that the transducer is installed and used correctly.
The radar must be set up before it is used for the first time.
See "Set up the radar before using it" in the Radar Installation manual.
Radar scanners emit electromagnetic energy at a frequency that can be harmful at close
range. Always keep the recommended safe distance from the scanner as follows:
| Vertical beam | Minimum safe distance |
Scanner | angle of scanner | (100 Watts per m² average |
Model | (degrees) | power density) Note 1 |
2 kW | 30 | 1.6 ft (0.5 m) |
|
|
|
4 kW | 25 | 3 ft (0.9 m) |
|
|
|
6 kW | 20 | 3.6 ft (1.1 m) |
|
|
|
10 kW | 20 | 9.5 ft (2.9 m) |
|
|
|
25 kW | 20 | 18 ft (5.5 m) |
|
|
|
Minimum safe distance (10 Watts per m² average power density) Note 2
4.6ft (1.4 m)
9.3ft (2.8 m)
11.5ft (3.5 m)
30 ft (9.0 m)
57 ft (17.4 m)
NOTES: Limits apply to exposure within the vertical beam angle.
Note 1: Peak occupational exposure limit pursuant to IEC 60936 Clause 3.27 and IEC 62252 Clause 4.32
Note 2: General public exposure limit pursuant to IEC 60936 Clause 3.27 and IEC 62252 Clause 4.32
