Failure to observe the following rules regarding location and use will result in poor performance of your MDW telephone.

•Position the carrier(s) in a central location, relative to the handset(s) usage area, leaving at least 6 feet (1.8 m) between the carrier(s) and the communications system switch/control unit or other wired phones. If your switch/control unit is located in a remote location, you may have to run a telephone line cord from your switch/control unit to the centrally positioned radio module or carrier(s). The line cord maximum length is 1,000 feet (305 m) of 26-gauge cable.

•The carrier(s) should be placed high on the wall for optimum voice quality and range. Allow 6–12 inches (15.2–30.5 cm) of space between the top of the antenna on the radio modules and the ceiling.

•The carrier(s) should never be installed above a drop, suspended ceiling.

•The carrier(s) should not be within 3 feet (.9 m) of any large metal object, and should not have metal objects in the line of sight to the operating area of the handset.

•The carrier(s) should not be within 6 feet (1.8 m) of equipment with microprocessors such as answering machines, personal computers, and fax machines; control units, communications system switches, or other phones (especially speakerphones); competing radio devices such as wireless bar- code scanners; electromagnetic equipment such as electric motors; or electrical main power feeds, junction boxes, circuit-breaker panels, fuse boxes, or 220-volt power lines.

•The carrier(s) should not share the same power line as equipment with microprocessors such as answering machines, personal computers, and fax machines; or electromagnetic equipment such as electric motors.

•If your communications system uses an uninterruptible power supply, such as a backup generator, you may want to connect the radio module or carrier(s) to that power supply.
