 24   Notes for Using the Detector -  Handling           FIGURE 6  DO NOT DROP  Handle the instrument carefully, as it may be damaged if something is hit against it, dropped, or receives a strong jolt. Embedded Mechanical shock sensor specification is 100G. -  Before Exposure If the instrument is used with condensation formed on it, problems may occur in the quality of the instrument. Sudden heating of the room in cold areas will cause condensation to form on the instrument. In this case, wait until condensation disappears before performing exposure.  When an air-conditioner is going to be used, be sure to raise/lower the temperature gradually so that a difference in temperature in the room and in the instrument does not occur, to prevent forming of condensation.  -  During Exposure Do not apply excessive weight to the sensor unit. Otherwise, the sensor may be damaged. The detector and patient must be taken from a fixed state. Otherwise, the performance may be degraded.
