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 telephone-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 #)

Programing Multiple Digital Desksets for Takeover Privileges
One or more desksets within a group can be configured for the supervisory takeover functionality associated with the Takeover button on the deskset. When the Takeover button
(on a deskset with supervisory takeover priviledges) is pressed once to the ON position,
the Busy LED on all other desksets will begin to blink. Effectively, no other deskset (even
other supervisors) can communicate on the radio channel until the operator initiating the
supervisor takeover, presses the Takeover button to the OFF position.
The desksets requiring supervisory takeover priviledges will require the Takeover button
be programed to the ON (enabled) position. The default position is OFF (disabled).
To enable/disable the Takeover button on a deskset:
You will need to set this in the deskset’s Configuration and Test program. For instructions
on how to access and use the program see “Configurations” on page 2-18. See option 13
‘Enable Takeover’ of Table 2-10, “Parameters and Parameter Values,” on page 2-19 for

Communication Options
Communication Options
Handset Operation
You use the handset to transmit and receive calls in a high noise environment or when
connected to a full duplex trunking radio station. You can transmit and receive at the same
time.
Using the Handset PTT Button
To transmit:
1. Lift the handset (off-hook).
2. Press and hold the PTT press bar in the middle of the handset. The Transmit LED
turns on while the button is pushed.
3. Speak into the mouthpiece.
4. Release the PTT press bar after you finish transmitting. The Transmit LED turns off
when the button is released.
Lifting the handset disables the internal microphone, which is the default audio transmit,
and allows you to transmit high quality audio in a full duplex mode. Always allow a short
delay after pressing the PTT button, and before speaking, to allow time for the radio channel to be established. When connected to a trunking radio station, always wait for the
grant tone before you begin to speak or your voice message may be clipped.
Note: When configuring the deskset, the installation technician has the option of disabling
the handset and/or the internal microphone.
To receive:
1. Lift the handset (off-hook).
2. Listen for receive audio in the handset ear piece.
Lifting the handset also disables the internal speaker, which is the default audio receiver,
and allows you to receive audio privately.
Enabling the Internal Speaker
You enable the internal speaker while the handset is off-hook to allow the receive audio to
be heard publicly while maintaining high quality transmit audio to the caller via the handset
mouthpiece.
Although the internal speaker and microphone are normally turned off (default) when the
handset is off-hook, you can temporarily turn the internal speaker on while the handset is
off-hook.
To turn the internal speaker on with the handset off-hook, press the Speaker button once.
The Speaker LED turns on.
To turn the internal speaker off with the handset off-hook, press the Speaker button again.
The Speaker LED turns off.
Note: Returning the handset to the cradle (on-hook) will turn the Speaker LED off.

Operation
Monitoring the Radio Channel
Monitoring the Radio Channel
You monitor a radio channel to verify that your transmission will not interrupt a radio communication between other radio systems sharing the radio channel. This is an FCC and
Industry Canada regulated radio procedure.
You will automatically hear any conversation initiated by all deskset consoles and radios
on your system without pressing the button corresponding to the Monitor button on the
digital radio. However, you will not hear conversation initiated by other radio systems that
may share the frequency until you press the Monitor button.
Note: Both the FCC and Industry Canada may assign numerous companies to share a frequency. In this case, separate tone codes are assigned to radios belonging to each company to offer a degree of privacy. These tone codes encode your radio transmissions so
that your receivers only hear radios belonging to your company (similar to party-line telephones).
Pressing the Monitor button disables the tone code on your receiver so you may temporarily listen to all conversations from all companies sharing the frequency.
You use the Mode Up and Mode Down buttons (which emulate the digital radio’s Mode/
Channel Selector) to select a radio channel and associated TX/RX frequency/ies you wish
to monitor or on which to transmit or receive. Only one radio channel can be monitored at
a time. This normally applies to conventional radio systems not trunking radio systems.
Optionally, to select a different radio channel:
1. Look at the top left hand corner of the LCD display and press the Mode Up or Mode
Down keys to find the desired Mode/Channel or Talk Group in a preset list based on
the configuration of your system.
To listen to the radio channel activity:
1. Press the digital radio function button that corresponds to the Monitor button of the
radio type the deskset is connected to. The Monitor LED turns on. Any radio communication audio on the channel will be heard on the internal speaker. Alternately, if the
handset is off-hook, you will hear the audio in the handset ear piece.
Release the Monitor button when you have verified that the radio channel is clear.
The Monitor LED turns off.
Dial-Up Connection to the Radio
You use the dial-up function to connect to a digital radio remotely through the telephone
lines. Both the Digital Junction Box the deskset is connected to, and the Digital Junction
Box the radio is connected to, must have a dial-up modem connection.
The dial-up modem requires two phone lines, one for data communication and one for
voice communication (audio). Thus, you must enter two phone numbers to connect the

Initiating or Answering a Radio Channel Transmission
The deskset is always in receive mode unless you press the PTT, Transmit or Intercom
buttons. When the handset is on-hook, the deskset mouthpiece continuously routes all
radio communication and intercom audio to the internal speaker. Alternately, if you lift the
handset (off-hook) the audio is heard via the handset ear piece.
To visually verify that you can initiate or answer a radio channel transmission, look at the
Busy LED. If the Busy LED is on, a parallel deskset is being used and you cannot transmit until the Busy LED is off.
The deskset can be connected to a radio configured for a conventional or trunked radio
system. A conventional system uses discrete frequencies. A trunked system selects a free
radio channel automatically and notifies you with an audible grant tone when a free radio
channel is found.
For a conventional system you use the Mode Up or Mode Down buttons to select a radio
channel and its associated TX/RX frequency/ies that you wish to monitor or on which to
transmit or receive. Only one radio channel can be selected at a time.
Note: The procedure for paging or making a Stat Alert page from a conventional radio
versus a trunked radio differ. Please refer to the specific digital radio’s user documentation for specific instructions.
Note: The procedure for making a telephone call from a conventional radio versus a
trunked radio differ. Please refer to the specific digital radio’s user documentation for
specific instructions.

Always allow a short delay after pressing the Transmit button, and before speaking, to
allow time for the radio channel to be established. For the best transmit audio quality,
maintain a speaking distance of 18 inches from the desk microphone.
Initiating or Answering an Intercom Transmission
You use the intercom to communicate between desksets without transmitting over the
radio channel/s.
To visually verify that you can initiate an intercom transmission, look at the Busy LED. If
the Busy LED is on, a parallel deskset is being used and you cannot transmit until the
Busy LED is off.
To transmit:
1. Press and hold the Intercom button. The Transmit LED turns on while the button is

receive audio from the internal speaker. The Transmit LED turns off when the button
is released.
To respond to an intercom call:
Press and hold the Intercom button only and speak into the internal microphone. If you
use the PTT press bar or the Transmit button, your response will be heard on the radio
channel as well as the intercom. You can only hear the receive audio if the Intercom button has been released.
