DO NOT CONNECT POWER UNTIL SYSTEM IS FULLY CONNECTED                                                                                                                             

1)  A cell signal is REQUIRED at the location of the window antenna. Check cell signal by looking at the bars on your cell phone and by making and completing a call. You must be able to make and complete a call near the location of the window antenna. The window antenna (426-PW) should be placed at the location where the cell signal is the strongest.

The window antenna should be placed on a clear section of glass and not behind metal or metal strips.
 If the window has tinting and the tinting may be removed in front of the window antenna.

2)  After the location of the window antenna is selected, slide the window antenna into the window mount (DM426).  Clean the window with window cleaner or an alcohol swab and secure the window mount with suction cups to the window.

In homes with small children, suction cups should be removed and double sided adhesive tape should be used to permanently secure window mount.

3)   Find a location for the DA4000PR repeater unit that faces into the room to cover the desired enhanced area.  The DA4000PR unit must be located 8' away from the window antenna and facing into the room with the backside facing the window antenna.

The DA4000PR unit must be located at least 8' diagonally from the window antenna
The DA4000PR unit and window antenna CAN NOT be located above and below each other. 

4)  Open the 15' coaxial cable (240-15NM) and carefully uncoil to prevent kinds or twists.  Securely attach the N type male connector to the N type female connector on the bottom of the window antenna.  Attach the mini-UHF female connector to the DA4000PR repeater unit.  Make sure connectors are lined up and securely hand tightened.

Do not sharply bend or deform cable.  Bends must have a radius great than 1 inch.
Only use Digital Antenna 50 ohm coaxial cables.
Extension cables and longer length cables available here at AccessoryGeeks.Com.

5) Only attach the electrical plug when the cable is connected to both the DA4000PR unit and the window antenna. Plug the DP255 AC adapter into the back of the DA4000PR unit and into a standard household 110 VAC electrical outlet. Only use the provided DP255 power supply.
