Kenwood TM-451A - Manual (Page 119)

Packet
This transceiver is equipped with a connector on the
Rear Panel designed specifically for Packet operation.
Packet is a data communications mode used to
exchange digital information that is typically created
using a personal computer. In other words, Packet
provides a method to link computers together via radio.
Page
A function that allows one station to signal another by
sending a transmission encoded with a Page code that
only opens the squelch of a receiver with the same code
selected. The calling station’s code appears on the
target station's display after a successful Page.
Page code memory
A memory channel dedicated to storing only Page codes.
See "Page".
Page Transmit Delay
The delay intentionally introduced at the transmitter to
delay transmission of Page codes after [PTT] is pressed.
The delay can improve the reliability of Page when
communicating with a receiver with slow response time.
Programmable Band Scan
A function that monitors sequentially all frequencies
within the programmable limits set by the user in a single
band. See "Scan".
PTT (Push-to-talk)
Refers to the non-latching switch on the microphone that
changes the transceiver from Receive to Transmit mode.
QSO
Refers to a contact between two Amateur stations.
Repeater
A station, usually installed in a central location at a high
elevation, designed to receive and re-transmit signals.
The purpose of a repeater is to increase the receive and
transmit range of stations able to access the repeater.
Reset (initialization)
The act of restarting the transceiver microcomputer.
Depending on the type of reset done, some or all
memory may be erased and set to default values. A
reset can be done as a last resort when the transceiver
appears to be malfunctioning.
