AT&T System 85 manual Out-of-Range Indication, Display Information

MDC 9000 Cordless Telephone

Display Information

The telephone display provides visual call and telephone status information through the following set of icons:

or or shows the status of the adjacent button. If the triangle and rectangle both appear, you are using that line; if only the rectangle 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 not used with DEFINITY or System 75 or System 85.

STAT appears when the status mode is active, refreshing the icons and indicating that you should move closer to the base.

MSG appears when there is a message waiting for you.

BATT appears when the battery is low.

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 the base in an optimum loca- tion. The base can be placed on a desk or mounted 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.
