• wood vs. metal construction
• metal vs. wood studs in wall construction
• thickness of concrete floors and walls (and type of covering, e.g. Metallic wall paper)
• number of floors and walls
• open office (cubicles) vs. closed office (floor to ceiling)
• steel partitions, elevator shafts, electric utility rooms
• RF LANs (Radio Frequency Local Area Networks), extensive machinery, computer
equipment, and other cordless phones or wireless devices
• Placement of the antenna is crucial for enhancing the performance of the T7406. Pick a central
location and mount the antenna with the following guidelines:
• Attach the base station at least eight feet from the floor.
• Minimize the number of walls between the base station and handsets.
• Centralize the location of the base station to make the number of interfering walls equal in all
directions.
• Do not mount the base station on an outside wall.
• Do not mount or place the base station outdoors.
• Adjust the antenna for optimal transmission by moving it through 90-degree angle planes (i.e.
perpendicular to the wall, parallel to the wall, perpendicular to the floor, parallel to the floor)
RF LANs (Radio Frequency Local Area Networks)
RF LANs are primarily installed in large chain businesses such as retail and grocery where the RF
LAN is used for inventory equipment.
With the correct selection of the T7406 operating band, the RF LAN operating at 900 MHz does
not pose an operating issue for T7406 nor does the T7406 pose issues for the RF LAN with respect
to data transmission capabilities. However, there may be instances where the T7406 user may hear
an occasional slight audio click when operating in a RF LAN environment. This should not inhibit
the user's ability to hold a normal two-way conversation using the T7406.
Telephone-to-Base Range
The T7406 cordless telephone utilizes an extremely efficient radio design to deliver the maximum
possible range while complying with the governing rules of the Federal Communications
Commission (FCC) and Industry Canada. The effective operating range within a site will largely
depend on the environmental characteristics mentioned previously, such as building construction
and internal layout of the site. Typically, the T7406 will provide an effective operating range of 95
meters (300 feet).
If the T7406 is not meeting this operating range, the following are some steps that can be taken to
assist with the troubleshooting:
• Check surroundings for any other product that my be causing interference.
• Check environment for obstructions that may be limiting the range.
• Change the orientation of the base station antenna.
