Introduction to this Manual
About this Manual
The purpose of this manual is to help you install and operate the MC3000 Digital Deskset.
It is written for operators and for the technicians who are responsible for installing and
troubleshooting the MC3000 Digital Deskset and related equipment. It provides reference
information for technicians and Motorola field support engineers and technicians.
The MC3000 Digital Deskset (L3223) is operated as an extension of four Motorola radio
system types (connected through the Digital Junction Box): ASTRO, MCS2000, iDEN and
LTR. As such, the digital radio function buttons will emulate the buttons and display of the
radio it is connected to. For detailed instructions on the operation of the radio buttons,
refer to the appropriate radio user documentation.
Note: The deskset default configuration is for an ASTRO digital radio. Refer to Chapter 2
if you connect the deskset to a different digital radio type.
MC3000 Deskset Overview
The MC3000 Digital Deskset is a small-footprint radio dispatch console designed to satisfy
the needs of digital radio users who require multiple dispatch points with enhanced talk /
listen and inter-dispatcher intercom.
The MC3000 is the approximate size and shape of an office telephone set, with a tele-
phone-like handset that includes a PTT switch. The handset microphone and speaker
become active when the handset is lifted from the housing base. The housing includes a
built-in condenser microphone and an internal speaker. The unit housing and handset are
both black in color. An external deskset microphone or footswitch can be connected to the
deskset.
Speaker volume can be adjusted using a knob on the front panel. The minimum level does
not mute speaker. Receive, transmit, and intercom transmit audio levels can be adjusted
using potentiometers inside the deskset housing. The front panel has the following buttons
and LEDs:
• Intercom (green LED)
• Speaker (green LED)
• Takeover (green LED)
• Transmit (red TX LED, yellow Busy LED)
• Keypad (1 -9, A - D in green, A - Z in black, * and #)
• Shift button (

• Menu / Home button
