    However, some types of blemishes can get worse over time and interfere with the usabil- ity of the device. If you believe a blemish is a cause for rejection, warranty or repair please ATN or point of purchase for warranty/ repair procedures.
  • Page 40 A bright spot is a small, non-uniform, bright area that may flicker or appear constant (Figure 3-3). Not all bright spots make the ATN PS-40 rejectable. Cup your hand over the lenses to block out all light. If the bright spot re- mains, return the ATN PS-40.
  • Page 41 C. Black Spots These are cosmetic blemishes in the image intensifiers or dirt or debris between the lenses. Black spots are acceptable as long as they do not interfere with viewing the image. No action is re- quired if this condition is present unless the spots interfere with the usability of the device.
