2.8 Connection of 2.4 GHz Portable Stations144 Installation Manual2.8.2 Procedure OverviewWhen connecting the wireless system, use extreme care in conducting the site survey. An incorrectlyperformed site survey can result in poor service area, frequent noise, and disconnection of calls.1. Investigate the installation siteRefer to "2.8.3 Site Planning".a. Obtain a map of the CS installation site.b. Identify the service area required by the user on the map.c. Plan the location of each CS, taking account of distance, building materials, etc.2. Prepare the CS for site surveyRefer to "2.8.4 Before Site Survey".a. Assign a CS number to each CS by setting the DIP switches on the back of the CS.b. Supply electricity to each CS using an AC adaptor or a battery box.c. Install each CS temporarily as planned.Notes• Install at least 2 m above the floor.• Keep the antennas in the upright position.3. Conduct the site surveyRefer to "2.8.5 Site Survey".a. Test the radio signal strength using the PS.Confirm that the radio signal strength level is "12" near the CS.Using the KX-TD7680Using the KX-TD7690b. By walking away from the CS with the PS, check the radio signal strength. The radio signal strengthweakens as you walk away from the CS.c. Map the CS coverage area at radio signal strength levels "3" and "8".d. Make sure that adjacent CS coverage areas overlap where the radio signal strength level is "8" byat least 5 m.e. Make sure that the radio signal strength level is greater than "3" at any location within the servicearea required by the user.Display example:Press 1, 9, and POWERfor more than 2 seconds.<< SEARCHING >> CS NO.1 LEVEL:12SAVE:01234567891 to 9CS No.1 9 0Display example:Press 1, 9, and POWERfor more than 2 seconds.<< SEARCHING >> CS NO.1 LEVEL:12SAVE:01234567891 to 9CS No.1 99 0
