2.8 Connection of DECT Portable Stations
Installation Manual 157
2.8.5 Site Survey Using the KX-TCA255/KX-TD7590
The PS has a Radio Signal Test mode that monitors the state of the radio link to the CS for site survey. In
the Radio Signal Test mode, the frame loss and signal strength of a synchronous slot, and the signal
strength of the other slots can be measured when the PS is monitoring the CS. After installing the CSs
temporarily as planned during site planning, set the PS to the Radio Signal Test mode and locate each CS
to measure its coverage area. Then, record the results on the map of the installation site.
Testing the Radio Signal Strength
After locating the CS(s) temporarily, execute the Radio Signal Test using the PS. The PS scans whether
there is a CS that can link with on channel 0 right after entering the Radio Signal Test mode. The channel
to be scanned can be changed by pressing the appropriate keys 0 through 9.
1. Enter the Radio Signal Test mode.

Notes
*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 of
errors out of 10 000 radio signal receptions. An increased number of frame errors indicates greater
radio signal interference and more frequent noise during conversation. The ideal number of frame error
is "0000".
CAUTION
Storing the scan data will clear all directory data.
2. Measure the radio signal strength by moving to and away from the CS.
