2.7 Connection of DECT Portable StationsInstallation Manual 1292.7.5 Site Survey Using the KX-TCA255/KX-TD7590The PS has a Radio Signal Test mode that monitors the state of the radio link to the CS for site survey. InRadio Signal Test mode, the frame loss and signal strength of a synchronous slot, and the signal strengthof the other slots can be measured when the PS is monitoring the CS. After installing the CSs temporarilyas planned during site planning, set the PS to Radio Signal Test mode and locate each CS to measure itscoverage area. Then, record the results on the map of the installation site.Testing the Radio Signal StrengthAfter locating the CS(s) temporarily, execute the Radio Signal Test using the PS. Directly after enteringRadio Signal Test mode, the PS scans channel 0 for a CS that it can connect to. The channel to be scannedcan be changed by pressing the appropriate keys 0 through 9.1. Enter Radio Signal Test mode.Using the KX-TCA255Using the KX-TD7590Notes*1: Channel number*2: Slot number*3: When a slot is synchronised, "SYNC" is displayed.*4: Radio signal strength level*5: Frame error (0000 to 9999)/Frame counter (0000 to 9999). Frame error indicates the number oferrors out of 10 000 radio signal receptions. An increased number of frame errors indicates greaterradio signal interference and more frequent noise during conversation. The ideal number of frameerrors is "0000".CAUTIONStoring the scan data will clear all directory data.2.
