3) Turn the Transceiver ON while holding
down the USER2 button. Wait for display to
indicate "Flash Update Mode"
4) Start the Update program
5) Select the COM port to which the
Transceiver is attached.
6) Choose UPDATE under the PROCESS
menu.
7) Select the RUF file under the Process
Menu.
8) The program will update the radio and
report any errors encountered. During the
update process the Orion screen will
indicate the current line being processed.

TROUBLESHOOTING

While we cannot cover every possible
problem, here are some hints for dealing
with some potential difficulties.
Check the obvious. Is your dc power source
okay? Check power supply, cable and
connector(s). Is the 25 ampere fuse loose or
missing? Antenna problems? Try a dummy
load. Is a proper antenna connected?
Is any external antenna switch connected
and properly set? Have you checked
ORION II's control settings? Have you
double-checked ORION II's many control
settings, including those on all MENUS
screens, for your intended mode of
operation?
Problem: No audio from receiver
If you are using the SUB Rx, does it have a
VFO and an ANT assigned?
If frequency controls act normally --
Which receiver are you controlling at the
moment?
What routing is set in the AUDIO menu?
If S-meter seems to be reacting to signals --
Is receiver squelched? Check squelch
threshold in the RX menu. Check setting of
RF gain controls for main or sub receivers.

Try a set of headphones in case the speaker
has failed.
Is either receiver muted from pushing the
SUB AF or MAIN AF encoders? Is the
volume on either turned all the way off?
Check inside the cabinet for cable
connectors that may have loosened in
shipment or rough handling.
Problem: Distorted SSB transmit
Be certain the mic gain is set properly. The
ALC LED should flash on voice peaks, but
not remain continuously lit.
Check the setting of the speech processor.
An excessively high setting can reduce
audio quality.
A frequent cause of a distorted SSB signal is
inadequate RF grounding resulting in RF
feedback. Common RF grounding problems
are no ground connection, or too long a lead
to a good ground. Many problems relate to
the lack of an RF station ground, as
contrasted with a safety ground connection.
We recommend bonding all equipment
chassis together with short heavy metal
braid or strap. Make these connections from
chassis ground lug to chassis ground lug
and connect the last piece in the chain
feeding the antenna to a good earth ground.
This lead needs to be as short as possible.
Lengths near ¼ wavelength on any band
used can be particularly troublesome when
the far end is connected to earth.
Another potential cause of distorted SSB
arises when the station is in the near field of
the antenna. This is a problem many
apartment dwellers face.
Distorted SSB transmit can result from
chassis ground and signal ground from the
microphone being tied together to a
common connection. This is a common
problem with third-party microphones.
Assure the chassis ground and signal
ground from the microphone are separated.
Problem: No transmit, but receiver(s) OK
Is one of the TX LED's on the buttons to the
far left of the transceiver lit? See the
discussion of buttons 8 and 9 as described
in Chapter 2. If neither of these two buttons
is lit, the radio will not transmit.
