2.7 Connection of DECT Portable Stations
2.7.2Procedure Overview
When connecting the wireless system, use extreme care to conduct a site survey. Site survey can be conducted using the
1. Investigate the installation site
Refer 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 survey
Refer 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 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 positions.
3.Conduct the site survey
Refer to "2.7.5 Site Survey Using the
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 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.
e.Make sure that the radio signal strength level is greater than "3" at any location within the service area demanded by the user.
4. Finish the site survey
Refer 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.
