1.1 Description
The UESCOPE®VL400 video laryngoscope system (the device) is a handheld
medical device that uses video camera to allow the operator to indirectly visu-
alize the glottis and larynx on the monitor. The device is an ideal tool for exam-
ination of the interior of the larynx and for placement of an tracheal tube. It is
also very helpful for teaching and clinical training of tracheal intubation in both
regular and difcult airway.

2 Operating Instructions
2.1 Getting Started
Please note that the devices are supplied non-sterile. Refer to Chapter 3 to clean
the device and accessories before using on patient for the rst time. Dispos-
able laryngoscope blades are supplied sterile and ready for single use only.
Twist-N-Lock™
The device’s Twist-N-Lock™ Connector is designed for quick and easy swapping
of video components such as video blades, video batons, and video stylets. It
helps to secure these components in place and prevent accidental disconnec-
tion during use.
Hold steady the lower portion of the monitor, not the screen itself. Insert the
handle in such a direction that the handle looks like a Letter J with the blade
tip pointing towards left. Turn the handle counter-clockwise to tighten and lock
the connection. Conversely, hold steady the lower portion of the monitor, turn
the handle clockwise to unlock and separate the handle from the monitor.

7
Charge the Battery
The device is powered by an internal rechargeable Lithium-ion battery. It is
highly recommended to fully charge the battery before rst use, using the
provided charger and cable.
During charging, a flashing green power indicator indicates that charging is
in progress, while a steady green power indicator indicates that charging has
completed. It may take up to 3 hours to fully charge the battery when no charge
remains.
During the long-term standby, the battery shall be checked and
recharged if necessary once every 2–3 months.
Load Disposable Blade
Open the peel pouch and slide the disposable blade over the VL400 Video
Baton. The blade is securely loaded when it is rmly latched to the anchor
point with a click sound.
Power Up
Press and briefly hold the power switch for 2–4 seconds to turn on the device.
A bright LED light should appear from the front end of the video component,
where the camera locates. The company logo should appear on the screen for
a few seconds. Then the scene taken by a high denition camera will be shown.
Observe the monitor screen to verify that a clear image is being displayed.
A steady green power indicator means the device is in normal working
state. A red power indicator means the battery is running low and
needs to be recharged immediately.
