The color of the blink indicates that information for test is unavailable
(orange), the receiver passed the test (green), or the receiver failed the
test (red).
1. To switch to EIM, press and quickly release (within one second)
the

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.

Clearing the MC-2.5 Receiver Box NVRAM
The receiver’s Non-
Volatile Random Access Memory (NVRAM) holds data required for
satellite tracking, such as ephemeris
1
data and receiver position. The
NVRAM also keeps the current receiver’s settings, such as active
antenna input, elevation masks and recording interval, and
information about the receiver’s internal file system.
Even though clearing the NVRAM is not a common (nor normally a
recommended) operation, there are times when clearing the NVRAM
can eliminate communication or tracking problems. Clearing the
NVRAM can be interpreted as a “soft boot” of your computer.
After clearing the NVRAM, your MC-2.5 Receiver Box requires
some time to collect new ephemerides and almanacs (around 15
minutes). Clearing the NVRAM of the MC-2.5 Receiver Box resets
the box to factory default values.
In addition, the NVRAM is used to keep information about the
receiver file system. Note that after clearing the NVRAM, the
receiver's LED(s) flashes orange for a few seconds indicating that the
receiver is scanning and checking the file system.
1. Ephemeris (ephemerides): Data giving the coordinates of a celestial
body at specific times during a given period.
