(Important) About the Waterproof/Dustproof and Anti-shock Performance of this unit [HM-TA20] Waterproof/Dustproof Performance This unit's waterproof/dustproof rating complies with the "IP58" rating. Provided the care and maintenance guidelines described in this document are strictly followed, this unit can operate underwater, to a depth not exceeding 3 m (10 feet) for a time not exceeding 60 minutes. (*1) Anti-shock Performance This unit also complies with "MIL-STD 810F Method 516.5Shock". This unit has cleared a drop test from a height of 1.5 m (5.0 feet) onto 3 cm (0.10 feet) thick plywood. In most cases this unit should not sustain any damage if dropped from a height not exceeding 1.5 m (5.0 feet). (*2) This does not guarantee no destruction, no malfunction, or waterproofing in all conditions. *1 This means that this unit can be used underwater for specified time in specified pressure in accordance with the handling method established by Panasonic. *2 "MIL-STD 810F Method 516.5-Shock" is the test method standard of the U.S. Defense Department, which specifies performing drop tests from a height of 122 cm (4.0 feet), at 26 orientations (8 corners, 12 ridges, 6 faces) using 5 sets of devices, and passing the 26 orientation drops within 5 devices. (If failure occurs during the test, a new set is used to pass the drop orientation test within a total of 5 devices.) Panasonic's test method is based on the above "MIL-STD 810F Method 516.5-Shock". However, the drop height was changed from 122 cm (4.0 feet) to 150 cm (5.0 feet) dropping onto 3 cm (0.10 feet) thick plyboard. This drop test was passed. (Disregarding appearance change such as loss of paint or distortion of the part where drop impact is applied.) 10 VQT3N87
