2.8 Connection of DECT Portable Stations
Installation Manual 147
2.8.2 Procedure Overview
When connecting the wireless system, use extreme care to conduct a site survey. Site surveys can be
conducted using the KX-TCA255 or KX-TD7590 PS. Inadvertent site survey can result in poor service area,
frequent noise, and disconnection of calls.
1. Investigate the installation site
Refer to "2.8.3 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 survey
Refer to "2.8.4 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 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 position.
3. Conduct the site survey
Refer to "2.8.5 Site Survey Using the KX-TCA255/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
Using the KX-TD7590
b. By walking away from the CS with the PS, check the radio signal strength. The radio signal 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 strength level is "8" by
at least 5 m.
