(+ 350 C  within 5 sec.) 2. Patterning should be followed by our recommended one. 3. Applying excessive excitation force to the crystal unit may cause deterioration damage. 4. Unless adequate negative resistance is allocated in the oscillation circuit, start up time of oscillation may be increased, or no oscillation may occur. How to check the negative resistance. Rf R X’tal Cg Cd Rd (1) Connect the resistance (R) to the circuit in series with the crystal unit. (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 + CI value. (5) Recommended -R -R> CI  (5 ~ 10) 5. The shortest patterning line on board is recommendable. Too long line on board may cause of abnormal oscillation. 6. To avoid mull function, no pattern under or near the crystal is allowed. Solder paste should be more than 150 m thickness. 7. This device must be stored at the normal temperature and humidity conditions before mounting on a board. 8. Too much exciting shock or vibration may cause deterioration on damage. Depending on the condition such as a shock in assembly machinery, the products may be damaged. Please check your condition in advance to maintain shock level to be smallest. 9. Depending on the conditions, ultrasonic cleaning may cause resonant damage of the internal crystal unit. Since we are unable to determine the conditions (type of cleaning unit, power, time, conditions inside the bath, etc.) to be used in your company, we cannot guarantee the safety of this unit when it is cleaned in an ultrasonic cleaner. 10. Ink marking may be damaged by some kind of solvent, please take precautions when choosing solvent by your selves. 11. Please refer to packing specification regarding how to storage the products in the pack. 6 Ver.20210820
