Step 1 - Remove the Radome
Follow the steps below to remove the radome.
a. Disconnect power from the TracVision
system and any connected receivers and/or
multiswitch.
b. TracVision M5 – Remove the four Phillips
screws securing the radome. Then carefully
remove the radome and set it aside in a safe
place (see Figure 1).
c. TracVision M7 – Remove the six Phillips
screws securing the radome. Then carefully
remove the radome and set it aside in a safe
place (see Figure 2).
Step 2 - Remove the Main PCB Cover
Follow the instructions below to remove the
main PCB cover. Be sure to remove the cover
carefully to avoid damage to the PCBs or cables.
a. TracVision M5 – Remove the six Phillips
screws securing the main PCB (see Figure 1).
Then remove the cover and set it aside in a
safe place.
b. TracVision M7 – Remove the seven Phillips
screws securing the main PCB (see Figure 2).
Then remove the cover and set it aside in a
safe place.
NOTE: If the TracVision M7 includes an inverter
PCB, do not disconnect any of its cables. Simply
lay the main PCB cover down to allow the
required access.
CAUTION
For your own safety, be sure to disconnect
power from all wired components before
performing this procedure.

Step 3 - Install/Replace the Gyro PCB
Refer to Figure 3 to determine if your TracVision
system includes a gyro PCB. If a gyro PCB is
currently installed, proceed to Option A. If a gyro
PCB is not currently installed, proceed to
Option B.
Option A - Replace an Installed Gyro PCB
Follow the instructions below to replace the gyro
PCB.
a. Place labels on the elevation and azimuth
gyro cables as needed to ensure proper
connection to the new PCB later (see
Figure 3).
b. Using cutting pliers, cut and remove the tie-
wrap securing the jumper cable connector to
the gyro PCB (see Figure 3).
c. Disconnect the jumper cable and gyro cables
from the gyro PCB (see Figure 3).
d. Remove the four Phillips screws securing the
gyro PCB (see Figure 4).
If the gyro connections are reversed, the
TracVision system will not operate properly.

e. Reverse these instructions to install the new
gyro PCB.
NOTE: Be sure to install the jumper cable
supplied in the kit with its ferrite coil installed
(see Figure 5), and secure the jumper cable’s
connector to the gyro PCB, using a supplied tie-
wrap (see Figure 6).

Option B - Install a Gyro PCB
Depending on the serial number, some
TracVision M5/M7 systems require installing a
gyro PCB and modifying connections. The
following instructions apply only to the serial
numbers specified below.
a. Using four supplied Phillips screws, secure
the gyro PCB to the standoffs (Figure 7).
b. Place labels on the elevation and azimuth
gyro cables as needed to ensure proper
connection to the gyro PCB (see Figure 8).

c. Disconnect the gyros from the main PCB.
Then connect them to the gyro PCB
connectors, as shown in Figure 9.
d. Install the ferrite coil onto the supplied
jumper cable, as shown in Figure 10.
e. Connect one end of the supplied jumper cable
to the gyro PCB. Then connect the other end
to the main PCB (see Figure 11).

Step 4 - Reinstall the Main PCB Cover and
Radome
Follow the instructions below to reinstall the
main PCB cover and radome. Be sure to position
the cover carefully to avoid damage to the PCBs
or cables.
a. TracVision M5 – Secure the main PCB cover
using the six Phillips screws you removed in
“Step 2 - Remove the Main PCB Cover” on
page 2 (see Figure 1 on page 2).
b. TracVision M7 – Secure the main PCB cover
using the seven Phillips screws you removed
in “Step 2 - Remove the Main PCB Cover” on
page 2 (see Figure 2 on page 2).
c. Reinstall the radome. Then restore power to
the TracVision system and any connected
receivers and/or multiswitch.
Step 5 - Calibrate the Gyros
Follow the steps below to calibrate the gyros for
use with the new gyro PCB.
a. Follow the instructions in the TracVision
M5/M7 User’s Guide to connect a PC to the
TracVision system.
b. Double-click the KVH Flash Update Wizard
shortcut on your PC’s desktop to start the
Flash Update Wizard.
NOTE: You do not need to flash the antenna; you will
simply type commands in the Flash Update Wizard’s
“TracVision Antenna Comms” window. Be sure to
click the “TracVision Antenna Comms” window to
select it before typing.
c. Type HALT then press Enter.
d. Type DEBUGON then press Enter.
e. Type =CALGYRO then press Enter.
f. Type ZAP then press Enter.
The procedure is complete!
