How to Set Up RAIM

RAIM (Receiver Autonomous Integrity Monitoring) is a diagnostic feature which tests
the integrity (accuracy) of the position fixing signal.
The receiver estimates position confidence using range value and detected satellite
error, and displays (provided the RAIM function is active) the results as one of three
levels of position confidence in the text data box of the GPS display mode only. The
three levels are as follows:
• [SAFE]: GPS signal is normal. The positioning accuracy satisfies the setting value.
• [CAUTION]: RAIM accuracy cannot be calculated. (Signals from five or more GPS
satellites are necessary for calculation.) The positioning accuracy does not satisfy
the setting value.
• [UNSAFE]: GPS signal is abnormal, therefore the positioning accuracy is not reli-
able.
To use the RAIM feature, do the following:
1. Open the [GNSS] menu.
2. Select [RAIM], then press the ENT key.
3. Select [RAIM FOR GPS], then press the ENT key.
4. Select [SETTING], then press the ENT key. An options pop up window appears.
5. Select [ON] to enable the RAIM feature, select [OFF] to disable the RAIM feature.
6. Select [ACCURACY LEVEL], then press the ENT key. A numerical input pop up
window appears.
7. Set the compensation for RAIM accuracy.
8. Select [ENTER], then press the ENT key to apply the RAIM settings, or select
[CANCEL] then press the ENT key ignore the settings changes.
9. Close the [MENU].

How to set the rollover timing

The SC-70/SC-130 uses the positioning system to calculated date and time. Date and
time data sent via satellite signal is reset once every few years, which can cause prob-
lems in date/time display. The rollover is used to prevent this from occurring. By set-
ting the correct year on your SC-70/SC-130, the satellites and your system become
synchronized.
1. Open the [GNSS] menu.
2. Select [RAIM], then press the ENT key.
3. Select [ROLL OVER], then press the ENT key. The [INPUT ROLL OVER] window
appears.
4. Enter the current year.
Press
the input cursor.
5. Select [ENTER] to apply the new setting, select [CANCEL] to keep the current set-
ting.
If you select [ENTER], a confirmation window appears. Select [YES] to confirm
and restart the system with the new setting.
