Using the Matrix KP-NUM Keypad

There are several “advanced” functions that are associated with the KP-NUM keypad (FIG. 56). These
functions use the “0 through 9” plus the “Star” or “Dot” and “Enter” buttons.
This numeric keypad allows for the use or programming of presets as well as Direct Numeric Access for
AM/FM stations, Multi Disc Changers, or other source components that have a numeric keypad on the
original remote control.

Direct Access Control

The user can enter commands via the numeric keypad to directly select favorite discs, tracks, stations and
channels. This provides an easy way in which to select material directly from the source component that
you know (such as the station ID or the disc/track number).

Direct Numeric Access - On Board AM/FM Tuner

Using the Numeric keypad, enter the station identification and press ENTER (FIG. 57).
Strings of 3 to 4 numbers are recognized.
If an * (asterisk) or • (dot) is part of the command string, then an FM station is assumed,
otherwise an AM station is assumed.
1. First enter the station (include the dot where applicable).
2. Press ENTER to execute the command.
