INTRODUCTION

The Zetron Model 360 Radio Remote is an attractive and rugged desktop remote designed to operate with Kenwood�s newest series of LTR� radios. Operating in conjunction with its companion radio interface panel, the Model 360 desktop remote brings the power and convenience of the popular Kenwood TK-780/880/980/981 series radio into an office or dispatch center environment. Up to 25 desktop remotes may be paralleled on the same radio to provide access from multiple points within an organization. The Model 360 even doubles as an intercom.

OPERATOR INTERFACE

The Model 360 provides a flexible operator interface that can be utilized in a variety of ways to best suit the requirements of the application. Normally, receive audio is monitored on a built-in speaker. Audio levels may be adjusted with the front-panel volume control. To transmit, the operator presses the transmit button and speaks into the built-in microphone.
Alternatively, the operator can use the telephone handset to minimize the disturbance to others in the room. Lifting the handset mutes the front-panel speaker and disables the built-in mic. For further flexibility, connection points are available on the Model 360 for a variety of external accessories including headsets, desk microphones, footswitches, amplified speakers and logging or instant recall recorders.

SPECIAL FUNCTIONS

Mute � A front-panel mute key silences the remote and disables all receive audio until the mute button is pressed again. A high-visibility LED provides a positive indication of mute status.

Privacy � The �Privacy� Key temporarily locksout parallel remotes from using the radio. When activated, all other users except for supervisory remotes are prevented from monitoring, transmitting, or altering radio settings. This feature supports a high degree of local privacy for sensitive radio communications.

Supervisor � A remote configured for supervisory operation has full transmit, receive, and control access to the radio regardless of the state of another remote�s Privacy Key.

Intercom � A value-added feature of the Model 360 is its ability to double as an intercom, allowing voice communications between all of the desktop remotes. Intercom mode operates as a "party line", and is selected by pressing the "ICOM" key from any position. Activation of the transmit key causes the user's voice to be heard at the other paralleled remotes without keying up the transmitter. Other positions can reply simply by pressing their transmit key. When finished, toggling the ICOM key returns the Model 360 to normal operation. If desired, the intercom function can be globally disabled through programming or individually disabled with a simple hardware modification.

A complete system is comprised of a Kenwood TK-780/880/980/981 radio, a Model 360 radio interface, and one to twenty-five Model 360 desktop remotes. The connections between the remotes and radio interface are made using six-wire cable (three twisted pairs). A 12-foot cable with RJ11 modular connectors is provided with each remote and radio interface. For installations involving greater separations, installer-supplied three-pair twisted cable may be used. An 18� eight conductor cable terminated with appropriate connectors is also provided to connect the radio and radio interface together.
