Re: Niles ZR-4630 Feature Update
In response to requests from Niles dealers, the ZR-4630 MultiZone Receiver (FG00813)
has been equipped with several new features. The updated features are:
1. An improved AM/FM Tuner provides superior performance.
2. A 75-ohm coaxial antenna connector replaces the spring-loaded 300-ohm dipole
FM antenna terminals.
3. Gold-plated 5-Way binding posts replace the No-Strip type speaker wire
connectors.

4. A new zone linking feature allows multiple zones to be controlled by a single Ci
Keypad or TS-1 Touch Screen. Activating this feature is simple:
a. Press and hold the program button until PGM MODE is displayed in the
tuner window.
b. Press the AM/FM button six times until ZL appears in the tuner window. You
may now create a group of zones that will respond to a single keypad by
pressing the tuner preset buttons that correspond to the zones you wish to
link. For example, pressing tuner preset buttons 4, 5, and 6, will link zones
four, five, and six. Only one group may be created per system.
5. The ZR-4630 Paging feature has been improved. A page will now broadcast
through any zone that is turned ON, even if the paging Dip Switch is set to the
disabled position.
The first version of the ZR-4630 MultiZone Receiver equipped with the updated features
will be designated Version 2.06 and will begin shipping in November of 2005.
