Held to face position For held to face position the flat section of a SAM Phantom or a flat phantom is used. The center of the radiating structure is to set on the middle position of the flat phantom. The distance between sample and flat phantom is 2.5 cm, similar to the real using. For the measurement head tissue simulating liquid is used. Belt Clip/Holster Configuration Test configurations for body-worn operated EUTs are carried out while the belt-clip and/or holster is attached to the EUT and placed against a flat phantom in a regular configuration. An EUT with a headset output it tested with a headset connected to the device. Body dielectric parameters are used. There are two categories for acce…
