2.7 Connection of DECT Portable StationsInstallation Manual 872.7.2 Procedure OverviewWhen connecting the wireless system, use extreme care to conduct a site survey. Site surveycan be conducted using the KX-TD7590 PS. Inadvertent site survey can result in narrowservice area, frequent noise, and disconnection of calls.1. Investigate the installation siteRefer to "2.7.3 Site Planning".a. Obtain the map of the CS installation site.b. Consider the service area demanded by the user on the map.c. Plan the locations of each CS, taking account of distance, building materials and 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 theCS.c. Supply electricity to each CS using an AC adaptor or a battery box.d. Install each CS temporarily as planned.Notes• Install at least 2 m above the floor.• Keep the antennas in the upright positions.3. Conduct the site surveyRefer to "2.7.5 Site Survey Using the KX-TD7590".a. Test the radio signal strength using the PS.Confirm that the radio signal strength level is "12" near the CS.b. By walking away from the CS with the PS, check the radio signal strength. The radiosignal strength weakens 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 strengthlevel is "8" by at least 5 m.e. Make sure that the radio signal strength level is greater than "3" at any location withinthe service area demanded by the user.4. Finish the site surveyRefer to "2.7.6 After Site Survey".a. Return all DIP switches of each CS to the OFF position, and stop supplying electricity.b. Turn off the PS.Display 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 channel
