OPERATING, MAINTENANCE &
TROUBLESHOOTING TIPS
• Never remove the SD card while taking a picture or recording a video. Doing so may
damage the card and erase or corrupt the photo or video.
• If the LCD remains or goes dark, make sure that the console and probe batteries are
adequately charged, and that both components are operating on the same channel.
• If live video begins to look spotty, streaky or intermittent, the likely reason is an under-
charged battery. Plug in the AC adapter/battery charger immediately.
• Avoid using corrosive liquids such as alcohol to clean either the LCD or the camera
head. To clean the camera lens and LEDs, use a cotton swab and a few drops of
water. To clean the LCD, use a soft cloth, cotton swabs and water. To clean the plastic
housings of the console and probe controller, use a soft, dry cloth.
• The probe is flexible to make it easy for you to inspect hard-to-reach areas. Never
insert or bend it by force, and never over-bend any part of the probe. Specifically:
• Do not bend the last 1 to 2 inches
of the probe by more than 110°
• Do not bend the probe at any other point
by more than 90°
• To avoid permanently damaging the
delicate wires and fiber optic cables inside
the probe, never curl it into a circle with a
diameter of less than 6 in.
• The camera head, LEDs and thread protector
ring are waterproof, but not acid-proof or fire-proof. Do not touch acidic, corrosive or
hot materials (see table below) or they will ruin the head.
• Unless you wish to install the 110° mirrored viewing tip, do not remove the thread
protector ring (Fig. 2, Callout 4). Never use the probe without attaching either an
accessory or the thread protector ring to it.
• When inspecting a vehicle, shut off the engine. Metal and liquid under the hood may
be hot. Do not get oil or gas on the camera head.
• If condensation forms inside the camera lens, let it evaporate before using the probe.
