The KX-FHD351 also features a powerful digital duplex speakerphone, giving you the convenience of
fielding your phone calls hands free. It's designed to provide crisp, natural sound without dropouts or clipping.
It's especially useful for group or business situations, such as conference calls, when others in the room can eas-
ily join the conversation.
The machine can be programmed to send a message to your pager when you receive a voice message. In
addition, caller ID data can be sent to your pager. If you answer an incoming fax call on a phone that operates
on the same line as your fax unit, Extension Line Transfer lets you simply press *9 to take the call from your
fax unit.
A feature called Quick Scan whisks your fax documents into memory, then sends them from memory to the
recipient. This saves time otherwise spent waiting for pages to go through individually. Broadcasting stores
documents in memory and faxes them in succession to multiple locations, avoiding the need for repeating the
task manually.
Caller-ID Compatibility with two-line LCD lets you see the name and number of all of your incoming callers
(of up to 16-characters) on the LCD readout. You can even print the list for your records. It's a great time-saving
feature for both business and personal use (this feature requires a subscription to a fee-based phone-company ser-
vice).
Distinctive ring detection gives you up to three telephone numbers on a single line, each with a different
ring pattern. This way you can tell who the call is for, simply by the sound of the ring. If you subscribe to a Dis-
tinctive Ring service, you can assign phone numbers for personal use, business use, fax use, and so on. (This
feature can only be used if you subscribe to a Distinctive Ring service from your telephone company.)
The telephone directory navigator makes searching through your phone directory easier than ever before.
Just use the navigator key to look through your directory list, and when the name you want appears, lift the
handset, and the number will dial automatically.
The unit's enhanced copier functions include: multiple copies (up to 50), enlarge (150 or 200 percent), re-
duce (to 92, 86, or 72 percent), and collate.

WORK, POWER AND ENERGY
Work. To lift a weight from the ground requires the expenditure of energy. In lifting the weight we have to
do work against the force of gravity. The amount of work done depends on the weight lifted and the height
through which it is raised, and so the unit by which work is measured is defined as the amount of work done
when a weight of
1 pound is lifted a vertical height of 1 foot. This unit is called the foot-pound and is written ft-lb. In the metric
system the unit of work may be chosen as the gram-centimeter or the kilogram-meter.
When a force acts to assist the motion of a body the force is said to do work on the body. When a force op-
poses the motion of a body the phrase “work is done against the force” is used.
We denote work by W. Since it is the product of two scalar quantities, work is a scalar quantity.
Power. The time rate at which work is done is called power. Power, like work is a scalar quantity. It can be
expressed in any units of work and time, as foot-pound per minute, ergs per second, etc. The units commonly
used in engineering, however, equal to 550 foot-founds per second; the continental horsepower, equal to 75
kilogram-meters per second; the kilowatt, equal to 10 ergs per second. The symbol for power is P. From these
