MDW 9000 Wireless Telephone
Distance and Installation Limitations
The MDW 9000 uses radio transmissions to communicate. The range depends on your particular
operating environment. For indoor use, intervening walls will reduce the phone’s range. Try to
stay away from concentrations of structural metal, such as steel and aluminum, or reinforced
concrete.
At least 6 feet is required between the radio module/radio base station and the phone system
switch.
Before you install the radio module or radio base station, note the following considerations:
When positioning the radio module or radio base station, try to place the unit in a central
location, relative to the handset usage area. If your switch is located in a distant area,
you may have to run line cord from your phone system to the centrally positioned radio
module(s). The maximum distance is 1000 feet of 26 gauge cable.
The radio module or radio base station should not share the same power line or be within
6 feet of equipment with microprocessors such as answering machines, personal com-
puters, and fax machines, or electromagnetic equipment such as electric motors.
For remote locations, an individual radio module can be installed in that area and
attached via line cord to the phone system. IROBS should be used in outdoor area.
The radio module or radio base station should be placed high on the wall for optimum
voice quality and range. Allow at least 1 foot of space between the top of the antenna on
the radio module(s) and the ceiling.
Install the single radio module within 3 feet of either side of, and within 6-8 feet above, a
properly grounded 3-prong electrical outlet that is not controlled by an on/off switch.
Install the radio base stations within 15 feet of either side of, and within 6-8 feet above, a
properly grounded 3-prong electrical outlet that is not controlled by an on/off switch.
If your phone system uses an uninterruptible power supply, such as a backup generator,
be sure to connect the radio or radio base station to that power supply.
