This section explains all connections needed to make and receive IP line and TEL line calls.
 To connect a Portable Station (PS) or computer to the unit.

1. Connect the unit to the desired IP network and/or telephone line.

• To connect to an IP network, connect a category 5 LAN cable to the LAN port and to a switching hub.
• To connect to a telephone line, connect a telephone cord to the LINE jack and to a modular telephone jack.

2.  Connect the AC adaptor cord of the included AC adaptor to the unit’s DC power supply input.

• To use PoE (Power over Ethernet), connect the LAN cable to a PoE compatible (IEEE802.3af)

switching hub. In this case the included AC adaptor does not need to be connected.

3. Connect the AC cord to the AC adaptor, then connect the AC cord to the power supply.

• Use only the included AC adaptor (PQLV216).
• Pass the AC adaptor cord through the groove on the bottom of the unit.
• This product cannot be used to make or receive telephone calls in the event of a power outage.
• 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.

• This product cannot be used to make or receive telephone calls in the event of a power outage.
• The AC adaptor must remain connected at all times (unless the unit is powered by PoE).
•  It is normal for the adaptor to feel warm during use.
• Ensure that the AC outlet that powers the unit is installed near the unit and is easily accessible.

Test Preparation: Prepare the following equipment which has been through an operation check; Test use AC adaptor, CPM installed
PC, SD card, USB cable, etc. 
[IMPORTANT]

When the housing is opened, be sure to carry out Beamforming Test. Perform MIC calibration in such a place as a quiet meeting
room with no noise interference and place KX-NT700RU on a desk.
