IMPORTANT NOTE AND PRECAUTIONS
Important
Read and save this Operating Manual carefully before attempting to operate the HF/VHF PT-8000A transceiver. This
manual contains important safety and operating instructions for the transceiver.
Precautions
WARNING HIGH VOLTAGE !
Never touch an antenna or internal antenna connector during transmission. This may result in an electrical
shock or burn of your skin by high-frequency.
WARNING !
Never apply AC to the DC socket on the transceiver rear panel. This will ruin the transceiver and may cause
fire.
CAUTION !
Never allow any object touch any internal parts or connectors on the rear panel of the transceiver. This
could cause electrical shock and severe injury.
PROTECT the transceiver from precipitation like rain or any liquid. Do not operate the transceiver in
excessively dusty or very humid environment.
PROTECT the transceiver from operation by any unauthorized person notably children.
AVOID placing and using the transceiver in areas with temperatures below -15°C or above +50°C. If
the environment temperature drops so low that the dew point is undercut, avoid operating before the
devices are dried completely.
AVOID placing the transceiver and the power supply against a wall. This may inhibit proper air circulation
and could cause overheat. Do not cover any air inlets and outlets at top, bottom and rear panel of the
devices.
USE CARE when connecting the transceiver to a linear amplifier. Keep in mind the performance limits or operating
ranges of electrical connectors and interfaces. Set the PT-8000A RF-output level to less than the linear amplifier’s
maximum input level to prevent amplifier damage.
USE CARE when not operating the transceiver with Hilberling T9 microphone. Others may have different pin
assignments and connecting to the transceiver may cause damage to the transceiver and the microphone.

3 INTRODUCTORY NOTES
3.1 Scope of Delivery
Examine your PT-8000A for signs of damage during shipping. Should any damage be apparent please take
appropriate measures (contacting your carrier). We recommend to retain all packing material – it might be used for
shipment of the radio.
Listed below are the hardware and all accessories delivered with your PT-8000A. Make sure you have received and
unpacked everything:
3.2 About this Manual
The PT-8000A represents primarily state of the art analog RF-design. However digital signal processing and
microprocessor controlled circuits add to this transceiver in a synergistic way. Hence, features and functions can be
easily improved and/or tailored to customer needs through updating the Hilberling GmbH firmware using the USB
interface (please have a look at Appendix A2).

In this manual the following signs and symbols are used:
The STOP sign indicates a warning that must be obeyed for safety reasons.
This sign indicates an important explanation or a specific advice which should be obeyed.
An additional information or explanation is indicated this way.
3.3 Notes on Placing
When selecting the place for operating the PT-8000A bear in mind the general limitation concerning
environmental conditions as outlined in the specifications and the cautions at the very beginning of
this manual (P. ii).
Always handle the PT-8000A with care – consider the weight of more than 50 lbs, please!
Please make sure proper air circulation. Do not cover any air inlets and outlets at top, bottom and
rear panel of the devices.
Choose the place of installation so that all connectors of the PT-8000A are reachable any time.
Select a power outlet that is capable to handle the power requirements. Connect your PT-8000A to
a proper ground system – which is important for optimum operation of any HF transceiver –
especially when operating high power by using an external amplifier. In the past, a ground
connection to a copper water pipe was often used for this purpose. Recent revisions to the National
Electric Code has made this practice a code violation. Bear in mind that modern supply water
installations utilize plastic pipe – which do not function grounding purposes. Never use a gas or
electric pipe since the connection could cause an explosion or electric shock. A good grounding
system not only prevents electrical shock but also helps to ensure trouble free operation and will
diminish television and broadcast interference (TVI/BCI).
For your convenience you might raise the front of PT-8000A and HN-8000 by unfolding and locking tilt bails
mounted at the front equipment feet into front position as shown on Fig. 1 (see next page).
PT-8000A Operating Manual v2.01.10 3
Fig. 1
If a large resistance will complicate the unfolding, please spread the bail easy for hurdle the locking
nib to avoid damage of the equipment foot.
3.4 Antenna Considerations / Antenna Tuner
Standing wave ratio (SWR) may increase significantly
when using an antenna outside of the specific
frequency range for which it is tuned. The final power
amplifier will operate at peak performance only when
its load is resistive – i.e. the SWR is close to 1.0.
Therefore the PT-8000A is equipped with an
automatic antenna tuner (ATU) which does not
actually tune the antenna. The ATU instead matches
the feed line to the final amplifiers so they always
“see” a SWR close to 1.0. The ATU has its limits –
tuning mismatches with SWR greater than 2.0 become
difficult and will exceed the capabilities of the ATU.
Using a tuned or resonant antenna with 50 Ohm
impedance at the feed point for the specific
frequencies is highly recommended. The purpose of
the ATU is to ensure that a resonant antenna can be
used at the limits of the band selected with optimum
performance of both PT-8000A and antenna system.
Never try to hook up a symmetrical open feeder line
(balanced, twin-lead, ladder line etc.) directly to the
PT-8000A. Instead use 50 ohm coaxial feeders only.
The connectors supplied on the PT-8000A are all Type
N.
With the ATU it is acceptable to use a broadband
antenna system like a log periodic or T2FD system
which trade wide bandwidth for an SWR ranging as
high as 2.0.

5 POWER SUPPLY HN-8000
5.1 General Description
Each PT-8000A is equipped with its power supply HN-8000, which delivers 13.8 V DC @ 8 A internal / 5 A external
and additional 50 V DC @ 14 A max., i.e. the overall performance is about 900 W.
Operating voltages from the mains can be in the range of 90 VAC to 260 VAC without any degradation in output
power. Only the efficiency will vary slightly. It complies with special regulations in some countries regarding power
factor compensation (PFC). The HN-8000 provides triple HF shielding and feedthrough filters.
In addition the HN-8000 provides an auxiliary output 13.8 VDC @ 5 A at the back panel, e.g. to deliver further
shack equipment.

7.1 Introduction
Prior to any operation of the PT-8000A read this Operation Manual carefully notably
before activating the transmitter.
The PT-8000A will be delivered with following presettings:
The preselectors of both RX are calibrated and all data are stored in RX-CPU
memory, which is buffered through a NiCd battery.
The transmitter is unlocked according to the band plans of that IARU region
(see Page 28) the PT-8000A is delivered.
The IARU region can be changed by software update.
Prior applying main power to the power supply HN-8000 please verify the following
points (7.2).

8.6 Pushbuttons with LED Status Display
To inform about the status of several main functions of the PT8000A – in addition to display information – some pushbuttons
are equipped with LED, respectively the status of fundamental
operating conditions are indicated by LED.
Status displays as follows:

8.7 LED Status Display
The three main modes of PT-8000A (MAIN-RX / SUB-RX / TX) are displayed with
colored LED.
The PT-8000A incorporates a transmitter and two independent receivers (MAIN RX
and SUB-RX). Both receivers are permanently operating. Even if a receiver is in the
background i.e. not fully accessible through all main controls the receiver is operating
with its last settings when it has been the active one.
One transmitter and two receivers are operated in three main modes:
MAIN-RX is active and SUB is working in the background
(green MAIN-RX LED glows)
SUB-RX is active and MAIN is working in the background
(yellow SUB-RX LED glows)
TX is operating (red TX-LED glows)
Note: The MAIN RX VFOs will always determine the transmit (TX) frequencies and
other operating parameters.
Exception Split-Mode: In this case the selected (displayed) SUB-RX-VFO determines the
transmit frequency (see Page 42).
The red LED EXT REF will be on when an external 10 MHz signal is representing the
frequency reference.
The internal 10 MHz system clock no longer takes effect.

9 MAIN- AND SUB-RX OPERATIONS
The PT-8000A incorporates a transmitter and two independent receivers (MAIN-RX
and SUB-RX). Both receivers are permanently operating. Even if a receiver is in the
background i.e. not fully accessible through all main controls the receiver is operating
with its last settings when it has been the active one.
Using MAIN- and SUB-RX allows duplex operation mode.
Each of the two RX provides again two VFO: VFO A and VFO B. The active VFO is
called selected VFO, the other is called VFO in standby (s. P. 40).
Two controls are doubled, hence for these functions MAIN-/SUB-RX are always
accessible regardless of their status active or stand-by:
1. The selected VFO of the active RX (usually MAIN-RX) is always accessible through
MAIN tuning knob. The selected VFO of the RX working in the background (usually
SUB RX) is always accessible through SUB VFO knob.
2. The volume of MAIN- and SUB-RX is permanently adjustable through the
respective controls MAIN and SUB.
Both knobs have a push function:
Pushing MAIN will turn off PT-8000A speaker, pushing SUB will turn off HN8000 speaker. (see also Page 54).
The push button MAIN/SUB (located in the cluster MODE) toggles between the two RX
changing their status active or background.
After power on the PT-8000A the MAIN-RX is the active one (corresponding SUB-RX is
working in the background).
LED MAIN-RX and LED SUB-RX indicate which RX is the active one and so which is
accessible through all knobs and buttons on the front panel.
In the upper left corner the display shows the label of the active one (MAIN or
SUB).
Frequency, mode, filter bandwidths and S-meters are displayed for MAIN and
SUB respectively (see Figure 24).
Activation of noise reduction (NR), noise blanker (NB), DSP Filter, DSP-Notch, IF-
Notch, preamplifier, preselector and the squelch marker are displayed exclusively
for the active RX.
operating in the
PT-8000A Operating Manual v2.01.10 21
Example
When toggling between MAIN- and SUB-RX the actual settings of the controls used at
last are not transferred to the new active RX – instead the former settings of this RX are
the actual one – until they are overwritten by the respective control.
The squelch threshold set to the RX working in the background will stay the actual one
when this RX becomes the active – until one touches the squelch control to set the
threshold to a new setting.
The large S-meter is always allocated to the active RX. The smaller S-meter is
indicating the field strength of the RX working in the background.
Transmitting (TX) is only possible when MAIN-RX is the active one and SUB-RX is
working in the background.
When transmitting the SUB-RX may be used to monitor own RF-signal. Receiving with
SUB-RX on a separate antenna is limited however: Excessive field strength may trip the
protection circuits. Receiving at frequencies adjacent to the transmitting frequency may
be limited even by the superior dynamic characteristics of the PT-8000A receivers which are of course finite.

10.3 DATA Transmission (Digital Operation Modes)
The function DATA enables to send out signals which modulate the transmitter by
using following inputs:
0 dBm AUDIO IN (microphone socket MIC-PTT pin 4, see Page 7 Tab. 6)
AUDIO DATA IN (J20 AUDIO IN/OUT pin 2, see Page 6 Tab. 4)
This is basically possible with all modes – where appropriate. Thus why it is called
„operation sub mode“
When pushing DATA button located in the cluster MODE:
DATA-LED will stay off.
DATA menu will be called up.
In case this softkey is activated the signal at the 0dBm input (MIC-PTT Pin 4)
will be transmitted when PTT is switched; the softkey will be displayed
inverse; DATA-LED will turn on.
In case this softkey is activated the signal at the AUDIO DATA IN input (J20
Pin 2+3/10) will be transmitted when PTT is switched; the softkey will be
displayed inverse as shown here; DATA-LED will turn on.
RTTY operation; the filter will be shifted according to the frequency offset of
modulation tones (2125 Hz / 2295 Hz); the softkey will be displayed inverse; the
display will show RTTY (to the left of frequency).
This softkey toggles the source of audio signals at AUDIO DATA OUT output (J20 Pin
11+3/10) between MAIN-RX and SUB-RX (display accordingly OUT MAIN or
OUT SUB).
In case this softkey is activated the signal at the AUDIO DATA IN input (J20 Pin
2+3/10) will be transmitted when PTT is switched by an external software command
(USB interface); the softkey will be displayed inverse.
TX 0dBm, TX DATA and DATA Mike are only working alternatively.
DATA mode may be selected in all operating modes.
Only when DATA mode is selected a PTT signal can be fed through USB interface
(handshake signal).
In case the DATA softkey menu is displayed pushing DATA will terminate the currently
active DATA mode (TX 0dBm,TX DATA or DATA Mike).
If the menu is not displayed pushing DATA will call it up and only a second push will
terminate the currently active DATA mode:
DATA-LED will turn off.

11 SELECTING FREQUENCIES
To select or change a frequency there are the following options:
Select with band buttons (see below).
Numerical input (see Page 32).
Recall from a memory channel (see Page 34).
11.1 Select with BAND Buttons
Pushing a band pushbutton selects one of two stored frequencies
within the desired band (see Table 13 and 14 / Page 28).
The MF and each HF amateur radio band (excl. 60 m) is allocated to
a pushbutton in the cluster BAND.
The VHF amateur radio bands and the RX-only range above 110 MHz
are accessible by button 0 VHF in the cluster MODE and additional
select in the VHF softkey menu.
Each band button stores two frequencies exclusively for this band. Pressing the button
again will toggle between the last two frequencies used within this band.
The last used frequency within a band is stored automatically, so the stored frequency
will change continuously when tuning within the band with VFO knob or STEP-VFO
knob.
In case the BAND limits are exceeded through tuning the last valid frequency that has
been stored will remain. Press button again for return the PT-8000A to the last used
frequency.
The two stored frequencies of a band are correlated to each VFO. Selecting the
alternate VFO will give access to another two frequencies in that band (which were
used with this VFO). Of course this is applicable for both MAIN- and SUB-RX.
Mode, filter adjustments (width/shift), antenna and tuning increments (STEP VFO) are
stored along with the respective frequency.
A numerical input of a frequency (see Page 32) within the selected band will overwrite
one of the two stored frequencies (the last frequency used).
11.1.1 HF Amateur Radio Bands
Pressing e.g. button 14 5 (located in the cluster BAND) selects the last used
frequency within the 20 m band of the selected VFO.
The VFO menu (see Page 41) will be displayed.
Pressing again will toggle between the last two frequencies used within this band.
Two more frequencies are allocated to the „stand-by“-VFO.

The following MF/HF amateur radio bands – slightly modified depending on IARU
region the TRX will operate – are defined in the PT-8000A software as TX bands. They
are directly selectable with band pushbuttons (except 60 m):
11.1.2 VHF Amateur Radio Bands
Pushing button 0 VHF located in the cluster MODE will call up the VHF menu (see
Page 29) and will recall the last used frequency on the last used VHF band (50 MHz,
70 MHz, 144 MHz or 110 MHz, the corresponding softkey will be displayed inverse).
Pushing the button of the current band (the softkey is shown inverse) switches to the
second frequency stored in this band.
The following VHF amateur radio bands are defined as TX bands in the PT-8000A and
selectable via button 0 VHF and the respectively assigned softkey (plus one additional
RX-only range):
If a transverter has been used the last time while VHF operation pushing button 0 VHF
will activate the transverter again, the corresponding frequency will be shown on the
display and the softkey Trans will be displayed inverse.

If one of the softkeys (144/50/28) is pushed and held, the transverter operation
frequency band is displayed instead of the standby VFO frequency, see Figure 35.
Using control STEP-VFO / MEM/CH
gives access to all transverter
operation frequency bands as listed
below (Table 15).
When releasing the transverter softkey
the new frequency band is transferred
and will be stored.
The following 13 transverter operation frequency bands are available:
When the PT-8000A operates in transverter mode the transmitter output is directed to
the TX-ext. connector on the rear panel (see Page 5 / Table 3 / socket J14).
A transverter for one of the bands shown in Table 15 must be selected so that it can
operate properly with drive power 10 m, 6 m or 2 m.
Maximum power level at J14 is +20 dBm.
Hooking up multiple transverters requires external distribution of TX signals from TX-ext.

11.2 Numerical Frequency Input ENTER
Pushing button ENTER located in the cluster MODE will call up the ENTER menu and
will activate the numerical frequency input:
The frequency display will show blanks for all digits. A cursor indicates („_“) which
digit can be edited.
The number of blanks/digits are shown depends on the resolution selected by using the
Softkeys STEP , STEP or STEP VFO (s. P. 41). E.g. the resolution is 1 kHz the
frequency will be displayed as follows:
Pushing the respective numbers from 1.8 1 to 28 9 allocated to the BAND
buttons (located in the cluster BAND) and 0 VHF (located in the cluster MODE)
will insert the digits from left to right.
Pushing button ENTER (cluster MODE or softkey) again will complete the input;
the RX transfers the frequency; the VFO menu will be displayed:
Numerical input will be aborted;
the last used frequency will be displayed instead;
the last used softkey menu will be called up.
The cursor will jump to the next left position; the last digit input will be deleted; a
leading empty digit will reappear.
Frequency input will be completed;
the RX transfers the frequency (function is the same as key ENTER in the cluster MODE
does);the VFO softkey menu will be displayed.

Because the numerical input always starts with the 100 MHz digit possibly the 0 VHF
button first must be pushed. So this digit disappears and the Cursor jumps one digit to
the right to the 10 MHz digit. These can be deleted as well by pushing 0 VHF button
again, the cursor jumps to the 1 MHz digit, etc.
It is not necessary to key all digits (e.g. “0”). Pushing ENTER after the last digit will set
all lower digits to zero. After a valid numerical input is acknowledged the frequency will
be displayed and the respective RX will operate on that frequency.
In case the least significant digit is typed in the numerical input is terminated and the
frequency is transferred to the respective VFO (Pushing ENTER is not required). The RX
operates with the new frequency.
In case the input is not acknowledged through ENTER or completely input or not
aborted through ESC, after a period of 10 seconds without any activity the numerical
input will be terminated and the last frequency used will be selected again. The last
used softkey menu will be called up.
If the entered frequency is outside of RX frequency ranges of the PT-8000A the VFO
will jump to the upper border of the next lower RX frequency range. If input frequency is
< 9 kHz it will jump to 9 kHz.
In case the input frequency is a valid BAND frequency one of the two stored
frequencies of this BAND will be overwritten by the numerical input.
In transverter operation two additional digits will be displayed for 1 and 10 gigahertz
range:
In this case the 1 Hz digit is not available for numerical input.

11.4 VFO Main Tuning Knob (active RX) and SUB VFO Tuning Knob (RX in the Background)
Primary means of tuning the active RX (MAIN- or SUB-RX) is the Main Tuning Knob
VFO. With a full rotation it generates 512 steps, so that depending on the chosen
tuning increments 512 Hz, 5.12 kHz, 51.2 kHz or 512 kHz can be run through.
The Tuning Knob SUB VFO generates 256 steps with a full rotation, so that depending
on the chosen tuning increments 256 Hz, 2.56 kHz, 25.6 kHz or 256 kHz can be run
through.
General frequency coverage of both RX is 9 kHz to 30 MHz, 50 to 54 MHz, 69.9 MHz
to 70.7 MHz and 110 MHz to 148 MHz. Due to the frequency scheme of the PT8000A the ranges between them are blanked out.
Transmit operation is only possible on the allocated amateur radio bands of that IARU
region in which one the TRX will operate after delivery (see Page 28 / Table 13 and
14).
In case the transmit boundaries are to be modified (commercial application; signal
generator operation; new amateur radio frequencies) please contact Hilberling GmbH
for further information about a software update.
The tuning increments of the VFO are adjustable through STEP selection, which is
allocated to the softkey menu VFO.
If the VFO menu is not displayed, push button VFO A/B (see Page 40).
Softkey STEP (towards fine tuning) decreases the tuning increments by power of 10.
Additional digits appear at the VFO frequency readout.
Softkey STEP (towards coarse tuning) increases the tuning increments by power of
10. Lesser digits appear at the VFO frequency readout.
Selectable increments are 1 Hz / 10 Hz / 100 Hz / 1 kHz.
Digits below the selected tuning width are set to 0 and will be displayed in dark grey.
PT-8000A Operating Manual v2.01.10 39
Fig. 48
Fig. 47
Each mode has been allocated a default tuning increment setting:
FM: 100 Hz
SSB / CW / AM: 10 Hz
Changing the operating mode will reset the current setting to default values.
11.5 STEP-VFO Control
Operation with knob STEP-VFO allows VFO tuning with further increments.
The STEP-VFO Control is placed in the cluster MODE. The control enables tuning in
10 kHz, 100 kHz and 1 MHz increments.
Pushing the knob activates the STEP-VFO function:
A cursor appears at the 100 kHz digit of the frequency display:
Turning the knob will now tune the VFO by 100 kHz steps.
Pushing the knob a second time will move the cursor to the 10 kHz digit. Turning
the knob will result in tuning the VFO by 10 kHz steps.
Pushing the knob a third time will move the cursor to the 1 MHz digit – hence
tuning can now be established by 1 MHz steps.
Pushing the knob again will result in a movement of the cursor again to the 100
kHz digit, then 1 kHz, 1 MHz, and so on.
Neither pushing the knob nor turning the control for more than 3 seconds will
terminate the STEP-VFO function. If re-activated by pushing the knob the cursor will
appear at the last used position.
When power up the PT-8000A and STEP-VFO will be activated the cursor will initially
occur at the 100 kHz position.

11.6 VFO Management
Both receivers (MAIN- and SUB-RX) have its own two VFOs – VFO A and
VFO B. Switching between VFO A and VFO B is established through VFO
A/B pushbutton. The button is located in the cluster VFO.
In addition to frequencies the VFOs store filter bandwidth and
operation mode.
When pushing button VFO A/B:
In case the VFO softkey menu is already displayed the active RX will change its
VFO (A⇨B or B⇨A).
If a different softkey menu is displayed the first push will call up the VFO menu.
The second push will alter the VFO A and VFO B.
Both frequencies displayed for the active RX will alter its
position. The white display always shows the selected VFO. The
VFO can be identified through the red nominators A
respectively B.
The smaller green display always shows the alternate VFO that
is in standby mode.
Only the SUB-RXs selected VFO frequency is displayed without its identifier A or B.

11.7 SPLIT Operation
VFO SPLIT operation in the PT-8000A is realized by using the MAIN and the SUB-RX.
The selected VFO from MAIN-RX determines the RX frequency; the selected VFO from
SUB-RX determines the TX frequency.
To enable VFO SPLIT operation, MAIN-RX must be the active RX and SUB-RX operates
in the background.
The PT-8000A stays in the current operation mode of MAIN-RX when transmitting,
even though there is selected a different mode in SUB-RX. Only the frequency of SUBRX will be used.
Procedure:
Tune with the active VFO from MAIN-RX to the desired receive frequency.
Tune with the active VFO from SUB-RX to the desired transmit frequency.
When pushing softkey SPLIT (VFO menu):
When pushing PTT, the desired frequency from SUB-RX will be used for transmit
instead of the receive frequency of MAIN-RX.
To the left of the Display, below operation mode indicator, SPLIT will be displayed
The softkey will be displayed inverse
Pushing SPLIT again will terminate VFO SPLIT operation.

12 FILTER BANDWIDTH AND SHIFT FUNCTION FILTER WIDTH / SHIFT
Filtering in the PT-8000A is obtained in the 1st IF @ 40.7 MHz with a 6-pol. Filter and
in the 2nd IF (IF-2) @ 10.7 MHz with an "IM3 Protector" said prefilter with bandwidth
0.5 kHz, 3 kHz and 15 kHz.
Prefilters are selected automatically depending on operation mode (default filter;
manual filter selection see Pages 59 to 62)
After passing through the 16-pol. quartz filter ladder the channel selection can be
further enhanced by Digital Signal Processing (DSP) working in the audio range.
The DSP performs the following tasks:
Interpolation between analogue filter bandwidths @ 10.7 MHz.
Slope increase of the filter flanks @ 10.7 MHz and elimination of effects of group
delays by the filters.
Shift the placement of the filters (SHIFT function respective band-pass tuning).
Activating DSP filtering is accomplished by the pushbutton FILTER located in the cluster
DSP (Bandwidth and Shift/Pitch see Page 46 – 12.2).
In case the FILTER LED is off (shown in pic 58) only the analogue (Xtal-) filters are
active. The selected bandwidth is displayed and graphically expressed (see Page 46 /
12.1).
When pushing FILTER:
The DSP will be activated.
FILTER-LED will be on.
The display will indicate “DSP” operation.
WIDTH and SHIFT control located in the cluster MODE is used to adjust the filter
bandwidth and to shift the passband across the spectrum.
Pushing the knob will toggle between WIDTH and SHIFT function, turning will select the
current value.
For specific feature in CW mode see Page 23.
Depending on operation MODE there are analogue filters available which are
interpolated in bandwidth by the DSP (see Page 46).

width (see chapter A1.6.6); below, the areas are arranged for the panorama display
of MAIN-RX/TX (II) and SUB-RX (III).
A vertical red line in the middle of both display areas depicts the center frequency of
the panorama display and therefore it represents the current frequency of the PT8000A. Right of center line is shown the frequency range above the PT-8000A
frequency, left of it appropriate the frequency range below.
A1.6.2 Automarker and Marker
The Automarker (light blue circular ring) indicates the strongest signal within the
current panorama width, for each MAIN- and SUB-RX.
The strength of this signal and the frequency shifting against center frequency are
displayed in the upper left corner of the relative display area using a light blue font
(Fig. A1- 4b).
Automarker is activated each time the program was started and can be de-activated
by clicking Automarker (Fig. A1- 4c).
The Marker (light green circular ring) can be used for indication of strength and
frequency of any desired signal in the panorama.

Do the same with the new PT-8000A firmware. If you get it on CD-ROM it is located
in the directory
D:\Firmware\
If the firmware exists as a compressed archive file (ZIP file) it must be unpacked before
further use.
A2.5 Install Update Program on PC
To start the installation double-click the file
setup_PT8000_Update.exe.
On CD-ROM it can be found in the directory \Software\.
If the file was first copied to the Windows desktop or to another directory on the hard
disk, e. g. to C:\Downloads\, double-click it there.
The update program will be installed by default into the standard directory
depending on current Windows version.
A program linkage (PT8000_Update) will be added by default to the Windows
start menu folder Start Programs PT8000_Update.
Optional a program linkage can be created on the Windows desktop.
A2.6 Connect PT-8000A to PC by USB Data Cable
To update the software (see the following chapter A2.7) connect the PC (any USB
connector; Type A) and the PT-8000A (connector J22, Type B, see Operating Manual
Page 5) using the included USB data cable.

A2.7 Start and set up the Update Program
The update program will be started from the Windows Start menu:
Start Programs PT8000 Update Start PT8000 Update
First the program checks whether the PC's internal serial port COM 1 is available and
not already in use elsewhere.
If COM 1 is available the update program will be connected automatically and a
message box will be displayed (Fig. A2- 2).
Click OK to close the message box; the program's main window will be opened
( continue with chapter A2.7.2 Select Firmware).
If COM1 is currently not available on the PC because another application already
has access to it, an appropriate error message will be displayed (Fig. A2- 3).
Now it is necessary to set the COM port manually (see the following chapter
A2.7.1).
A2.7.1 Manual COM Port Setting
After clicking OK in the error message box (Fig. A2- 3), the Set COM port
window (Fig. A2- 4) will be opened to select a different COM port (in the
background the main program window already will be displayed).
It is advisable now to proceed in ascending order, i.e. next, select COM
port 2 by clicking COM 2.
If there appears a message box similar to Fig. A2- 2, then COM Port 2 is
connected. Click OK to close both this box and the Set COM port window
( continue with chapter A2.7.2 Select Firmware).
However, if there appears a message box similar to Fig. A2- 3 (error
message), then next, select COM port 3, etc.
If no unconnected COM port can be found, close the Set COM port
window (Fig. A2- 4) by clicking Close.
The program's main window will open (Fig. A2- 7). The large button in the
middle of the main window labeled NO COM PORT (Fig. A2- 5) indicates the
missing link.
In this case stop the update program (click Exit) and all other applications
running on the PC.
Then restart the update program and try again as described above to get a COM port
connection.

A2.7.2 Select Firmware
If COM port 1
(or another port) is
available, the program's
main window will open
with a corresponding
entry in the large
middle button. (If a
different COM port is to
be used, click the
button).
The entry No file in the field Update File indicates that no operation program has been
selected yet:
Use the Browse button to navigate to the directory where you have stored the new
operation program(s) (firmware) received from Hilberling GmbH, e.g. C:\Downloads\.
