2.3. Maintenance
This product is a precision RF Shielding Enclosure manufactured to be sturdy and robust. In order to ensure the optimal
performance of the product, periodic inspection is required according to the number of uses and period of use.
2.3.1 Recommended Routine Maintenance and Method
* Check to ensure that the Module, Hinge, and Latch screws are not loose and tighten if necessary.
* Check to ensure that the torque of the hinge mounted on the door has not weakened. The hinge has passed the
30,000 open-close private cycle test, but the torque may weaken as the number of openings and closings increases.
However, weakening of hinge torque does not affect the shielding effectiveness.
If the torque is weak, the lid could shut abruptly at a certain point, so please be careful as it may be hazardous. If
necessary, please contact customer support or an agent for replacement. It can be replaced by the customer, but
special attention and consultation are required as it may affect the shielding effectiveness.
* Check for damaged cable harnesses and replace them if necessary.
* Shielding performance may be greatly reduced if metal corrosion or oxidation progresses on the surface that the
gasket touches on the door or on the gasket frame. Clean thoroughly with alcohol and a soft cloth. It must be kept
clean at all times.
* Typically, the shielding effectiveness performance of new products has passed
10,000
open-closed private cycle
tests. However, it is recommended to replace the gasket if the shielding performance does not improve even after
regular maintenance has been performed.
* To maintain the shielding effect, refer to the performance test on page 7
. It is recommended
to perform a test approximately every 5,000 times or at intervals of 6 months.
2.3.2 Recommended EMI Gasket replacement Period
* Generally, after opening and closing the door about 30,000 times, the gasket's contact surface may be damaged. In
this case, perform routine maintenance first, and if it does not improve, replace the gasket.
* Generally, long-term storage of the product with the door closed may affect the elasticity of the foam gasket to
decrease even if it is used less than the recommended number of lid openings and closings.
In this case, perform routine maintenance first and keep the door open for more than one day, and then perform
the performance test. If there is no improvement, replace the gasket.
