• Delimiter - an easily distinguishable double-blink that shows the overall status of
tests performed in EIM. The STAT LED color for delimiter is calculated from the
colors of other STAT LED blinks.
–Orange: at least one blink is orange.
–Red: no orange blink and at least one red blink.
–Green: all other cases.
• Sufficient data for position computation.
• GPS S/N ratios are good (Table 4-2).
• GLONASS S/N ratios are good (Table 4-2).
• Oscillator's frequency offset is less than three ppm.
• Oscillator's Allan Variance is better than 2.7e-10.
• Continuous tracking time is more than 15 minutes.
In EIM, the STAT LED blinks seven times per cycle. Each blink could be orange, red,
or green.
• Orange – information for test unavailable.
• Green – receiver passed the test.
• Red – receiver failed the test.
1. To switch to EIM, press and quickly release (within one second) the FN key on the
MinPad.
2. Watch for the delimiter double-blink. With good receiver, antenna, and observation
conditions, all blinks should be green within 15 minutes of powering on.
• Green - ok
• Orange - wait
• Red - some tests failed
3. To switch back to normal, press the FN key.
