Care and Maintenance
This precision optical device includes components that
should be treated with care when handling. Although Greenlee
Communications has designed this product with field rugged-
ness in mind, the user must take certain precautions when
handling this device. Keep all protective dust caps in place
when tool is not in use.
Probe Optical Lens Care and Cleaning
The optical lens assembly is located on the tip of the probe.
To access the external surface of the lens assembly, remove
the adapter tip. To remove the adapter, hold the adapter in one
hand and gently rotate the adapter tip ring in a counterclock-
wise position with the other hand. Do not turn the focus ring
to attempt to remove the adapter tips. Once the adapter tip is
removed, the external lens assembly may be inspected and/
or cleaned. To clean this surface, gently wipe off debris with
appropriate lens cleaning solutions.
Display Maintenance
The GVIS 300 display case comes housed in a padded protec-
tive nylon case. Although this case provides field abuse pro-
tection, the GVIS 300 display must be protected from direct
impact. Should the display need surface cleaning, optical
grade cleaning solutions and tissues may be used.
GVIS 300 Battery Maintenance
The GVIS 300 includes a rechargeable lithium-ion battery
capable of powering the unit for more than 8 hours of continu-
ous use. The GVIS 300 includes a "smart charging adapter"
that charges the GVIS 300 and shuts down the charging when
fully charged. Approximately 3 hours is necessary for a full
charge. If the display does not power on when the power
switch is pressed, insert the AC charger into the lower right
side charge port. Power to the display will be restored once
the charger is connected.
