• Never install the radio module or carrier(s) above a drop, suspended ceiling.
• Do not locate the radio module or carrier(s) within 3 feet (0.9 m) of any large
metal object, and be sure no metal objects are in the line of sight to the operating
area of the handset.
• Do not locate the radio module or carrier(s) 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.
• Be sure the radio module or carrier(s) does 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.
Additional Rules for
Installing a Single
Radio Module Only
• Installing a single radio module on a shelf or desk is not recommended, because it
greatly reduces the range and quality of the transmission.
• Install a single radio module within 3 feet (0.9 m) of either side of, and within 6 to
8 feet (1.8 to 2.4 m) above, a properly grounded, 3-prong electrical outlet that is
not controlled by an on/off switch.
• You can install a single radio module in a remote location using a telephone line
cord to connect the radio module to the communications system switch/control
unit. IROBs must be used for out-of-building installations.
!
CAUTION:
A radio module cannot be installed outdoors.
