Refer to "3.9.8 Wall Mounting".

a. If there are no problems in testing, mount the CS on the wall.

Understanding Radio Waves

Characteristics of Radio Waves

The transmission of radio waves and the CS coverage area depend on the structure and materials of the building.

Office equipment, such as computers and fax machines, can interfere with radio waves. Such equipment may create noise or interfere with the performance of the PS.

The illustration below shows the special transmitting patterns of radio waves.

1.	Radio waves are reflected by objects made of materials such as metal.
2.	Radio waves are diffracted by objects such as metallic columns.
3.	Radio waves penetrate objects made of materials such as glass.

Relationships Between Radio Waves and Building Structure and Materials

•	The CS coverage area is affected more by the building materials and their thickness than the number of obstacles.
•	Radio waves tend to be reflected or diffracted by conductive objects and rarely penetrate them.
•	Radio waves tend to penetrate insulated objects and are rarely reflected by them.
•	Radio waves penetrate thin objects more than thick objects.
•	The table below shows the transmission tendency of radio waves when they reach objects made from various materials.

Object	Material	Transmission Tendency
Wall	Concrete	The thicker they are, the less radio waves penetrate them.
	Ferroconcrete	Radio waves can penetrate them, but the more iron there is, the more radio waves are reflected.
Window	Glass	Radio waves usually penetrate them.
	Glass with wire net	Radio waves can penetrate them, but tend to be reflected.
	Glass covered with heat-resistant film	Radio waves are weakened considerably when they penetrate windows.
Floor	Ferroconcrete	Radio waves can penetrate them, but the more iron there is, the more radio waves are reflected.
Partition	Steel	Radio waves are reflected and rarely penetrate them.
	Plywood, Glass	Radio waves usually penetrate them.
Column	Ferroconcrete	Radio waves can penetrate them, but the more iron there is, the more radio waves tend to be reflected or diffracted.
	Metal	Radio waves tend to be reflected or diffracted.
Cabinet	Steel	Radio waves are usually reflected or diffracted, and rarely penetrate them.
	Wood	Radio waves can penetrate them, but they are weakened.

CS Coverage Area

The example below shows the size of the coverage area of 1 CS if it is installed in an area with no obstacles.

Note Radio signal strength levels are measured during the site survey (refer to "3.9.5 Site Survey").

Site Survey Preparation

1.	Obtain a map and investigate the installation site.
	a. Check the obstacles (e.g., shelves, columns, and partitions). b. Check the materials of the structures (e.g., metal, concrete, and plywood). c. Check the layout and dimensions of the room, corridor, etc. d. Write down the above information on the map.
2.	Examine the service area required by the user on the map, referring to the following example.
	a. Draw the coverage area around a CS. Extend the coverage area 30 to 60 meters (98 to 197 feet) in each direction, depending on the materials of the building structures and obstacles in the installation site. Note that a CS cannot be installed outside a building. b. If one CS cannot cover the entire service area, install additional CSs as required. Overlap the coverage areas of adjacent CSs. Where CS coverage areas overlap, the PS will start call handover to the next CS if the signal from one CS becomes weak. However, if a PS moves away from a CS and there are no CSs available for handover, the PS may go out of range and the call could be lost. If the signal from the CS fades, due to the structure of the building, there may be some handover delay. The user will hear a range warning before handover in this case. This also applies in the case of interference from 2.4 GHz apparatus.

Example: Installing in a Room Separated by Interior Walls

Things to take note of:

• The room is separated by interior walls. • The room is surrounded by concrete walls.

CS installation plan:

• The coverage area of each CS will not extend as far as when there are no obstacles, because the radio signals will be weakened by separating walls. Therefore, you will need 5 CSs to cover the entire room.

Setting and Installing the CS Temporarily for Site Survey

1.	Switch the Radio Signal Test switch from OFF to ON.
2.	Set the CS number switches as desired.
3.	Set the Power Supply Select switch as desired (KX-T0151/KX-TDA0152 only).
	KX-T0151/KX-TDA0152
	KX-T0141/KX-TDA0142
	Note If more than 1 CS is in Radio Signal Test mode, each CS must have a unique CS number.
4.	After setting the DIP switches, connect the CS to an AC adaptor/battery box using a power supply adaptor.
	Notes • The AC adaptor should be connected to a vertically oriented or floor-mounted AC outlet. Do not connect the AC adaptor to a ceiling-mounted AC outlet, as the weight of the adaptor may cause it to become disconnected. • If the Power Supply Select switch is set to ON in step 3, connect the CS to an AC adaptor/battery box. If it is set to OFF, connect the CS to a CSIF/DLC/DHLC card (KX-T0151/KX-TDA0152 only).
	KX-T0151/KX-TDA0152 KX-T0141/KX-TDA0142
5.	Install the CS temporarily for the site survey. Install the CS at least 2 m (6 ft 7 in) above the floor, keeping the antennas in the upright position.

Registering the PS

The PS must be registered to the PBX before it can be used. Programming of both the PS and PBX is required. A PT with multiline display (e.g., KX-T7636 6-line display) is required to perform the PBX system programming.

Note For details about system programming using a PT, refer to "1.13.30 PT Programming" in the Feature Manual, and "2.1 PT Programming" in the PT Programming Manual.

Setting the Personal Identification Number (PIN) for PS Registration

To prevent registering the PS to a wrong PBX, a PIN for PS registration can be set to the PBX. Before registering the PS to the PBX, enter the PIN set to the PBX into the PS. By doing so, the PS will only be registered to the PBX with the matching PIN.

Notes • By default, the PIN for PS registration is "1234" for both the PBX and PS. Therefore, the PS can be registered to the PBX without setting the PIN. • The PIN for PS registration will only be used when registering the PS to the PBX. Therefore, during normal operation after registration, even if there is more than 1 PBX with the same PIN near the PS, the PS will not be inadvertently linked to a different PBX.
