RSSI is determined so that the correct badge is given credit for the Proximity Event 3 A badge that starts in Zone 1 or Zone 2 and then moves into Zone 3 or Zone 4 can still communicate with the A760 and therefore still receive credit for the Proximity Event even if it is in Zone 3 or 4 at the time when the winner is decided and communicated to the system 4 Because the immediate compete and ignore thresholds as well as the polling cycle requirements are user adjustable the A760 can be adapted to monitor a variety of different Proximity Events depending on the range and dwell time requirements of each situation PN01908 REVOO 7 R Figure 2 A760 Antenna Pattern A760 Zone 1 Immediate Notes for A760 Proximity Locator and Tag Deployment L If there is IR interference in a deployment area the tag s RF signal will not be affected but the IR location code will Note not be received by the tag To avoid any IR interference refer to the following notes e IR enabled active tags are NOT designed to work outdoors In direct sunlight the IR tags will not detect the A750 transmissions e Do not cover the IR sensor by wearing the badge under a jacket or in a pocket This will affect the ability of the tag to read A750 signals e A Room Locator s transmissions can interfere with other Room Locators operating within the same location The A750 Room Locators have a team operating mode to allow multiple room locato
