GVIS 300 Probe and GVIS 400-HDP Probe
1. Adapter Tip Ring – Adapter tips allow the GVIS 300 and
GVIS 400 to access either the bulkhead panel connec-
tor or the actual connector end if access is available. The
GVIS 300 and GVIS 400 are supplied with two adapters,
the SC bulkhead adapter and a 2.5 mm universal adapter
tip to allow inspection of any 2.5 mm ferrule connector
(SC, ST, or FC).
To connect the appropriate adapter tip, place the tip on
the end of the probe, being careful to screw the adapter
to the adapter tip ring completely and finger tight only.
Do not hold or turn the focus ring while attaching the
adapter tip. For bulkhead adapters it is helpful to align
the key of the adapter tip to the center position facing the
user.
2. Focus Ring – Two focus methods are used to adjust the
image while using the GVIS 300 and GVIS 400. The first
technique is used when using any of the universal tips for
direct connector inspection. To focus, insert the connec-
tor into the adapter tip and adjust the image by turning
the focus ring with your thumb.
To focus on the bulkhead connector surface, these probes
use a unique focus system by using specially equipped
adapter tips. These bulkhead tips include keyway devices
to lock the GVIS probe into the bulkhead under inspec-
tion. To focus on the bulkhead, simply insert the bulkhead
adapter tip into the bulkhead and rotate the probe slightly
in either direction for full focus control. The probe may be
held anywhere while rotating, allowing for much easier
focus control.
3. Probe Body – The probe body houses the optical inter-
face, camera system, and lighting system. The probe
body contains no user-serviceable devices inside the
housing. Refer to the maintenance section for proper care
of the optical interface at the tip of the probe.

Display Case – The display case includes the 3.5 inch
LCD display, battery, and control features to display the
required image. No user serviceable components are
found inside.
5. Conn/Probe – This control button is for possible future
functionality only. If the button is inadvertently pushed,
push it again so that the display toggles back to the active
probe display.
6. Probe Input – Insert the probe connector to the connec-
tor port located on the side of the GVIS 300 display case.
Power to the probe is automatic and will remain powered
while connected. To conserve battery use, remove the
probe from the display case during periods of inactivity.
7. Brightness Control – Adjust brightness with the up/down
arrow buttons. (The GVIS 300 has a default position of
two positions below the brightest possible image.) This
brightness control allows the user to discern defects with
greater ease.
8. AC Charger input – If the GVIS 300 display does not
illuminate the screen when powered on, then the battery
must be charged. To charge the battery and simultane-
ously use the GVIS 300, insert the AC charger connector
into the port on the lower left side of the display case.
Total charge time is approximately 3 hours. A green LED
on the charger indicates a fully charged battery. While
charging, this LED remains red.
9. Power On – This green LED indicates that power is avail-
able to the LCD and probe. During low battery conditions
this LED remains in the off position.
10. USB Port – Connect the accessory USB cable to the USB
port on the GVIS 300 monitor and then to a USB port on a
personal computer to view the image in the GVIS soft-
ware. An image can then be viewed and saved within the
GVIS application.
11. Power – Enable power to the GVIS 300 display by press-
ing the power control button. Pressing this button while
the unit is on powers the unit OFF.
