There are two methods to light up the LED back-light : (Please indicate while ordering.)
(1) Add +4.05V between LED A & K directly. (Default)
(2) Short JP1&JP3 and use current-limit resistor(R9/R10), use the same power (+5V) with the
logic circuit.

13 QUALITY AND RELIABILITY
13.1 TEST CONDITIONS
Tests should be conducted under the following conditions :
Ambient temperature : 25 ± 5°C
Humidity
: 60 ± 25% RH.
13.2 SAMPLING PLAN
Sampling method shall be in accordance with MIL-STD-105E , level II, normal
single sampling plan .
13.3 ACCEPTABLE QUALITY LEVEL
A major defect is defined as one that could cause failure to or materially reduce
the usability of the unit for its intended purpose. A minor defect is one that does not
materially reduce the usability of the unit for its intended purpose or is an infringement from
established standards and has no significant bearing on its effective use or operation.
13.4 APPEARANCE
An appearance test should be conducted by human sight at approximately 30 cm
distance from the LCD module under flourescent light. The inspection area of LCD panel
shall be within the range of following limits.

14 HANDLING PRECAUTIONS
(1) A LCD module is a fragile item and should not be subjected to strong mechanical shocks.
(2) Avoid applying pressure to the module surface. This will distort the glass and cause a
change in color.
(3) Under no circumstances should the position of the bezel tabs or their shape be modified.
(4) Do not modify the display PCB in either shape or positioning of components.
(5) Do not modify or move location of the zebra or heat seal connectors.
(6) The device should only be soldered to during interfacing. Modification to other areas of
the board should not be carried out.
(7) In the event of LCD breakage and resultant leakage of fluid do not inhale, ingest or make
contact with the skin. If contact is made rinse immediately.
(8) When cleaning the module use a soft damp cloth with a mild solvent, such as Isopropyl or
Ethyl alcohol. The use of water, ketone or aromatic is not permitted.
(9) Prior to initial power up input signals should not be applied.
(10) Protect the module against static electricity and observe appropriate anti-static
precautions.
