2.7.2 Procedure OverviewWhen connecting the wireless system, use extreme care in conducting the site survey. Site surveys can beconducted using the KX-TCA255/KX-TCA256/KX-TCA355/KX-TD7590 PS. An incorrectly performed sitesurvey can result in poor service area, frequent noise, and disconnection of calls.1. Investigate the installation siteRefer to "2.7.3 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 for site surveyRefer to "2.7.4 Before Site Survey".a. Check and assign the CS ID number to the PS.b. Assign a channel number to each CS by setting the DIP switches on the back of the CS.c. Supply electricity to each CS using an AC adaptor/battery box or by connecting them to a Super HybridPort or a DLC card.d. Install each CS temporarily as planned.Note• Install at least 2 m above the floor.• Keep the antennas in the upright position.3. Conduct the site surveyRefer to "2.7.5 Site Survey Using the KX-TCA255/KX-TCA256/KX-TCA355/KX-TD7590".a. Test the radio signal strength using the PS.Confirm that the radio signal strength level is "12" near the CS.Using the KX-TCA255/KX-TCA256/KX-TCA355Display example:RADIO STRENGTH<<< MEASURING >>> RADIO STRENGTHCH0 SLOT:06 SYNCL:12 0000/0100CS-ID:9005301234Press 1, 9, and POWERfor more than 2 seconds.1 99 00 to 9Channel No.To surveyspecific channelUsing the KX-TD7590Display example:RADIO STRENGTH<<< MEASURING >>> CH0 SLOT:06 SYNCL:12 0000/0100CS-ID:9005301234Press 1, 9, and POWERfor more than 5 seconds.1 99 00 to 9Channel No.To surveyspecific channelb. 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".124 Installation Manual2.7.2 Procedure Overview
