3.9.5 Site Survey Using the KX-TCA255/KX-TCA256/KX-TCA355/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 strength ofthe other slots can be measured when the PS is monitoring the CS. After installing the CSs temporarily asplanned during site planning, set the PS to Radio Signal Test mode and locate each CS to measure its coveragearea. 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 entering RadioSignal Test mode, the PS scans channel 0 for a CS that it can connect to. The channel to be scanned can bechanged by pressing the appropriate keys 0 through 9.1. Enter Radio Signal Test mode.Using the KX-TCA255/KX-TCA256/KX-TCA3550 to 9Log No.To store the scan dataPress 1, 9, and POWERfor more than 2 seconds.1 99Previous or Next 0 to 9Channel No.To survey other slots To survey specific channel/RADIO STRENGTH<<< MEASURING >>> RADIO STRENGTHCH0* 1 SLOT:06* 2 SYNC* 3L:12* 4 0000/0100* 5CS-ID:90053012340Display example:Using the KX-TD7590Display example:RADIO STRENGTH<<< MEASURING >>> CH0* 1 SLOT:06* 2 SYNC* 3L:12* 4 0000/0100* 5CS-ID:9005301234 0 to 9Log No.To store the scan dataPress 1, 9, and POWERfor more than 5 seconds.1 99 0Previous or Next 0 to 9Channel No.To survey other slots To survey specific channel/*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".Installation Manual 1733.9.5 Site Survey Using the KX-TCA255/KX-TCA256/KX-TCA355/KX-TD7590
