Before using the product under any conditions other than those specified therein, please consult with us to verify and confirm that the performance of the product will not be negatively affected by use under such conditions. In addition to the foregoing precautions, in order to avoid the deteriorating performance of the product, we strongly recommend that you DO NOT use the product under ANY of the following conditions: 1. Max three (3) times re-flow is allowed. Its recommended to manually solder when not enough/no solder detected. (Using soldering iron at +350 C Max within 5 seconds) 2. Patterning on a board should follow our company recommended pattern. 3. Too much exciting shock or vibration may cause deterioration on damage. The product may damage depends on the condition such as a shock in assembly machinery. Please check your process condition in advance to minimize and maintain the shock level. 4. It is recommended to do patterning to the oscillator as short as possible. Abnormal oscillation may happened if the line is too long. 5. Condensation may occur when products are used/stored under remarkable temperature change. 6. This product may be affected to ultrasonic cleaning. It is depends on the cleaning conditions (Cleaning machine type/power/time/content/position etc.). The warranty will not cover any damage due to this type of usage. Check conditions prior to use. 7. When the substrate of oscillation become dewy, the crystal frequency is changed or stopped. Please use under without the dewfall. 8. Applying excessive excitation Drive Level to the crystal Unit may cause deterioration damage. 9. Few data or readings taken at user side may be different from our company's data. Confirmation of the different value is necessary before application. 10. To avoid malfunction, no pattern across or near the crystal is allowed. 11. Start up time of oscillation may be increased or no oscillation may occur unless adequate negative resistance is allocated in the oscillation circuit In order to avoid this, please provide enough negative resistance to the circuit design. How to check the negative resistance. Rf Rd X'tal Cg R Cd (1) Connect the resistance (R) to the circuit in series with the crystal resonator. (2) Adjust (R) so that oscillation can start (or stop). (3) Measure (R) when oscillation just start (or stop) in above (2). (4) Get the negative resistance -R = R + R1 alue. (5) Recommended -R -R > R1 x 5 12. Please refer to packing specification for the storage method and packing standard.
