At least 6 feet (2 m) is required between the radio module or carrier(s) and the communi-
cations system switch/control unit.
The radio module or carrier(s) should be placed high on the wall for optimum voice
quality and range. Allow at least 6 inches (15.2 cm) of space between the top of the
antenna on the radio modules and the ceiling.
The radio module or carrier(s) should never be installed above a drop, suspended
level ceiling.
The radio module or carrier(s) should not be within 6 feet (2 m) of equipment with
microprocessors such as answering machines, personal computers, and fax
machines; electromagnetic equipment such as electric motors; or electrical main
power feeds, junction boxes, circuit-breaker panels, fuse boxes, or 220-volt
power lines.
The radio module or 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 uninterruptable power supply, such as a backup
generator, be sure to connect the radio module or carrier(s) to that power supply.
Additional rules for 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 (1 m) of either side of, and within 6 to 8 feet
(2 to 2.6 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.
Additional rules for installing one or more carriers:
■
Install carrier(s) within 15 feet (5 m) of either side of, and within 6 to 8 feet (2 to 2.6 m)
above, a properly grounded 3-prong electrical outlet that is not controlled by an on/off
switch.
■
Choose a location where handset users will not approach the carrier(s) within a radius
of 6 feet (1.8 m) for 1 or 2 carriers or 10 feet (3.1 m) for 3 carriers.
■
Carrier(s) cannot be exposed outdoors to the elements.
■
When installing multiple carriers:
– Install multiple carriers 1 foot (0.3 m) optimally to 4 feet (1.2 m) apart.
– Install multiple carriers on the same horizontal axis (do not install one carrier
higher or lower than another).
– Install the control carrier as the leftmost carrier, using only the expansion cables
provided.
– There must always be a radio module in slot 6 of the control carrier.
