appears, the line is in use.
■ ON appears when the handset is on.
■ RANGE flashes to indicate that you are out of range and appears steadily
when you have lost communication.
■ P is

Out-of-Range Indication
While the set is still active, it gives an audible indication (double beep) and visual
indication (the RANGE icon appears on the LCD display) when the handset is
getting out of range.
Distance and Installation Limitations (for the
Charging Base)
The MDC 9000 uses radio transmissions to communicate. The range depends on
your particular operating environment, and the range can be improved by placing

on a wall.
Before you install the phone, note the following considerations:
■ Mount the base near the center of the area in which the handset will be
used, but at least 20 feet away from the phone system switch.
■ Install the base within 6 feet of 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 base for the cordless phone to
that power supply.
■ The base should not share the same power line or be within 6 feet of
equipment with microprocessors such as answering machines, personal
computers, and fax machines, 900 MHz wireless LANS and other
