Vertically polarized position 3 4 First see if the Transmitter signal can be decoded by the Locator If the signal is strong enough the unit will start to beep once approximately every half second Each beep corresponds to one transmission of the Transmitter Some transmissions may be missed due to the movement of the Transmitter or other objects in the path between the Transmitter and Locator zes Locator User Manual 3 5 If the Transmitter cannot be located immediately try another 360 sweep with the antenna held such that the elements are horizontally positioned see figure 3 Horizontal polarization position NOTE the front of the antenna is at the end which has the shortest of the 4 elements the antenna cable runs off the back end of the antenna 3 6 If still unable to detect the desired Transmitter plug in the headphones and listen for the distinctive thumping sound of a Transmitter To distinguish this sound from other possible noises a Transmitter produces a regular heartbeat type of sound about every half second The volume control can be found on the headphone cable The antenna can be held by the handle or at the back end of the boom best performance will be achieved by holding the antenna as far from your body as possible 3 7 When close to the facility the majority of the sounds may come from inside the building from other patients so try to move away from the building somewhat until only the wandering patient s T
