| UNIT 6: MULTI-CELL WIRELESS - LESSON 2: SITE SURVEY Site Survey (continued...) If a second Portable Station is being used to monitor Cell Station 2, follow the same procedures used earlier. The Portable Station must be turned off to start. While the Portable Station is off, press and hold down the digits 1 and 9, then press and hold down the Power button for approximately 5 seconds. The Portable Station will then turn on in the Site Survey mode. To exit the Site Survey mode, turn the Portable Station off by holding down the Power button for 5 seconds once again. The display will show the following: To enter the Site Survey mode, press the digit 0. The display will show the following: To test the signal strength of Cell Station number 2, press the digit 2. When the Portable Station has established communications with the Cell Station, the display will show the following: Note: It is possible to use several Cell Stations and Portable Stations at the same time during the Site Survey. As you can see there are several ways of conducting a Site Survey and the installer’s preference and the availability of equipment will vary from site to site. Now you are ready to continue with the Site Survey. With the Portable Station at the 16 to 33 foot mark within the first Cell Stations boundary and reading a signal strength of 12, have your partner begin to move toward the area within the building that requires coverage. When the signal strength reads 7, have your partner move back toward the Cell Station until the signal strength just reaches a steady reading of 8. Now using the Portable Station define the signal strength 8 and 3 boundaries and mark the spots on the floor plan and at the physical locations. Again, repeat the procedure of adjusting the position of Cell Station and establishing the signal strength 8 and 3 boundaries until the maximum coverage is attained. Now you have established the location of the second Cell Station. This process of establishing the best possible location for the Cell Stations should be repeated until the entire location has a signal strength of overlapping areas of 8 for up to 4 Cell Stations. That completes the Site Survey process. Now it is time to install the KX-TAW848 and Cell Stations. Note: Remember to set all DIP switches back to the OFF position prior to installing the Cell Station at a customer’s location. The Cell Station will not function under normal Multi-Cell conditions if the Cell Station is in the Site Survey mode.
