(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a
breakdown or an accident.
Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclu-
sive-use soldering iron is recommendable.
(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering
capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land
separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when
completion of soldering is confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip
after completion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
CAUTIONS
THERE IS A RISK OF EXPLOSION IF THE BATTERY
IS REPLACED BY AN INCORRECT TYPE.
PROPERLY DISPOSE OF USED BATTERIES ACCORDING
TO THE INSTRUCTIONS.
LEAD-FREE SOLDER
The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.
The alphabet following the LF mark shows the kind of lead-free solder.
CAUTIONS
THERE IS A RISK OF EXPLOSION IF THE BATTERY
IS REPLACED BY AN INCORRECT TYPE.
PROPERLY DISPOSE OF USED BATTERIES ACCORDING
TO THE INSTRUCTIONS.

CHAPTER 1 OUTLINE OF THE PRODUCTS
1. MAIN FEATURE
1- 1. Simultaneous Writing for Up to 4 People
- This monitor lets you capture ideas at the moment of creation. Recognising up to 10 touch points, it allows up to four people to write at the
same time with a finger or touch pen. Each pen boasts a thin 3.5 mm tip that makes it easier to add detailed notes that remain legible
when printed out.
Note: Two touch pens are bundled with the monitor.
1 - 2. Featherlight Touch for Precise and Smooth Operation
- Thanks to the monitor’s precise position detection, only intentional input from fingers and touch pens appears on the display. Employing
Sharp’s original capacitive touch technology—which achieves high sensitivity and precision by reducing the noise level to one-eighth that
of conventional models - the monitor eliminates unwanted noise to deliver a clear onscreen signal.
1 - 3. Frontside Access to USB Port
- For increased convenience when the panel is mounted on a wall, this monitor's features a USB input on the front that connects to the
set-top box on the back of the unit. Now there’s no need to reach around the back of the monitor when you want to connect a peripheral
device.
Note: The set-top box is sold separately.

PN-L803C/80TC3 OUTLINE OF THE PRODUCTS 1 - 2
1 - 4. Frontside Access to USB Port
- Sharp Touch Viewer* is a touch-operated onscreen user interface that lets you easily manipulate different types of files, including
Microsoft® Office applications, videos, and web pages. Being able to simultaneously open and handle a variety of file types allows you to
have more active meetings.
* Check with your local Sharp authorised dealer/representative for details on how to obtain this software.
1 - 5. Multi Board Function (Sharp Pen Software)
- Up to three units can be connected and used to display sequential pages that can be navigated by swiping side to side. With the Multi
Board function*, meeting participants are better able to grasp the overall flow of a presentation.
* Requires a compatible version of Sharp Pen Software. Check with your local Sharp authorised dealer/representative for details. Only
one unit can be operated at a time.
1 – 6. Other Value-Adding Functions
- Multiple displays can be wall mounted together
- Safe design incorporating rounded corners

When mounting the monitor, be sure to use a wall-mount bracket that complies with the VESA-compatible mounting method.
SHARP recommends using M6 screws and tighten the screws.
Note that screw hole depth of the monitor is 3/8 inch (10 mm). Loose mounting may cause the product to fall, resulting in
serious personal injuries as well as damage to the product. The screw and hole should come together with over 5/16 inch
(8 mm) length of thread. Use a bracket which has been approved for UL1678 standard, and which can endure at least 4 times
or more the weight of the monitor.
