Table 4-1 on page 4-5 summarizes FN key functions and REC LED
statuses. See “FN Key Mode parameter” on page 2-23 for information
on setting FN key modes.
• Pressing the FN key for less than one second switches the
receiver between different information modes (normal and
extended information), or between static and dynamic postprocessing modes, depending on the receiver's configuration.
During the first second of pressing the FN key, the REC LED is
orange.
• Pressing and holding the FN key for more than one and less than
five seconds will start/stop data recording.
During data recording the REC LED is green.
If the REC LED is red, the receiver has run out of memory, has a
hardware problem, or contains an improper OAF (see “Option
Authorization File (OAF)” on page 1-16 for more information on
OAFs).
• The REC LED blinks green each time data is written to the
internal receiver’s memory.
You set the data recording time interval using PC-CDU. See
“Recording Interval parameter” on page 2-20 for information on
setting this function.
P/N 7010-0713

Information Modes
The receiver has two information modes: Normal and Extended
Information Mode (EIM).
Normal
In normal mode, the STAT LED indicates the number of tracked
satellites and the position’s computation status.
Extended Information Mode (EIM)
Extended Information Mode (EIM) is used for receiver testing
purposes. In this mode, the receiver continues to work as usual, but
the STAT LED indicates “extended” information using a delimiter.
The Delimiter is a distinguishable double-blink that shows the overall
status of tests performed in EIM. The LED color for delimiter is
calculated from the colors of other LED blinks, and will be one of the
following colors when the tests complete:
• Orange – at least one blink is orange.
• Red – no orange blink and at least one red blink.
• Green – all other cases.
The delimiter double-blink is followed by six LED blinks
corresponding to six receiver tests, where each blink indicates the
following information:
Blink 1. Sufficient data for position computation.
Blink 2. GPS S/N ratios are good (Table 4-2 on page 4-10).
Blink 3. GLONASS S/N ratios are good (Table 4-2 on page 4-
10).
Blink 4. Oscillator’s frequency offset is less than three ppm.
Blink 5. Oscillator's Allan Variance is better than 2.7e-10.
Blink 6. Continuous tracking time is more than 15 minutes.

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 FN key on the MINTER.
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 mode, press the FN key.
Downloading Files to a
Computer
When your survey finishes, you can download survey files to a
computer for storage, post-processing, or backup. Also, the receiver
memory holds a finite amount of files and information, so
downloading the files prevents files from being lost.
You should download files as soon as possible after collecting data at
the jobsite. PC-CDU provides a File Manager to download files to
your computer and delete files from the receiver.
1. Connect your receiver and computer. See “Connecting the
Receiver and a Computer” on page 2-10 for this procedure.

HiPer XT Operator’s Manual
Managing Receiver Memory
Managing Receiver Memory
When using the receiver in static or dynamic applications, you may
need to know the amount of memory the receiver’s log file occupies.
The specific memory size depends on the type of data being recorded.
Use the formulas below to compute the approximate size of the
receiver’s log files. These equations are based on the default set of
messages.
• SS – the estimated size of one epoch of raw data in the receiver’s
log file (expressed in bytes).
• N – the number of observed satellites per epoch.
When recording only L1 data:
SS = 183 + 22*N
When recording L1 and L2 data:
SS = 230 + 44*N
Clearing the NVRAM
The receiver’s Non-Volatile Random Access Memory (NVRAM)
holds data required for satellite tracking, such as ephemeris 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 in your receiver can be interpreted as a “soft boot” in your
computer.
After clearing the NVRAM, your receiver will require some time to
collect new ephemerides and almanacs (around 15 minutes).
Clearing the NVRAM of your receiver will not delete any files
already recorded in your HiPer XT’s memory. However, it will reset
your receiver to factory default values.
P/N 7010-0713
4-17
Operation
In addition, the NVRAM keeps information about the receiver file
system. Note that after clearing the NVRAM, the receiver's STAT
LED will flash orange for a few seconds indicating that the receiver is
scanning and checking the file system.
Using MINTER to Clear NVRAM
1. Press the power key to turn off the receiver.
2. Press and hold the FN key.
3. Press and hold the power key for about one second. Release the
power key while continuing to hold the FN key.
4. Wait until the STAT and REC LEDs are green
5. Wait until the STAT and REC LEDs blink orange.
6. Release the FN key while the STAT and REC LEDs blink orange.
Using PC-CDU to Clear NVRAM
1. Connect your receiver and computer. See “Connecting the
Receiver and a Computer” on page 2-10 for this procedure.
2. Click Too ls Clear NVRAM (Figure 4-11). The REC LED
flashes green and red; the STAT LED flashes red.
