Installation Safeguards
WARNING - DO NOT install the unit where
it would interfere with the proper
operation of automatic collision
protection devices (air bags).
WARNING - DO NOT install the unit where it
would likely cause injury in case of
accident.
A. Select a location for the radio where you can easily see
and reach all controls, including the microphone.
B. Using the radio mounting bracket as a template, mark
the spots with a pencil where the bracket securing screws
will be located.
NOTE - Before drilling holes in the vehicle, verify that
there is nothing that could be damaged or get
in the way by drilling and putting screws in this
location. It is better to use existing passages in
the dashboard, trunk, and floor for the routing
cable, thus avoiding excessive drilling.
After drilling holes for the mounting bracket, attach
bracket to surface using the two large Phillips head screws.
5

C. Install the radio unit to the bracket using the two large
black screw knobs, two spring lock washers, and two large
flat washers.
NOTE - Depending on the location where the radio unit
will be mounted, it may be more convenient to
install the microphone bracket before installing
the radio unit into the radio bracket.
D. Mount the microphone bracket to the most convenient
side of the radio unit, using the two small Phillips head
screws. There are two options for installing the microphone
bracket, allowing the on-hook placement of the micro-
phone from either the top or the front of the bracket.
E. Connect the DC power supply cord to the radio. If
necessary, the power supply cord may be connected
before mounting the radio unit to the radio bracket.
6

F. Push the modular microphone connector into the
microphone jack (located in the front of the radio unit)
until a click is heard.
CAUTION - Some electronic fuel injection, anti-
skid braking systems, cruise controls,
and vehicle alarms may be prone to
interference from radio frequency
energy or may malfunction due to a
lack of protection from RF energy. If
the vehicle contains such equipment,
consult the dealer to get help
determining whether the electronics
equipment in the vehicle will operate
properly when the radio is transmitting.
The radio is not intended for operation in a positive ground
vehicle.
You must purchase an antenna for proper operation of the
radio. Consult your dealer to determine which antennas are
suitable.

SM-2000 Series Operation
Power On- Volume
Rotate the on /off-volume control clockwise to turn the
power on. Adjust to the desired volume level. Turn the
radio off by rotating the volume control counter-clockwise
to detent.
Channel Select
Set the channel selector knob to the desired channel.
Green back-lit numbers indicate the channel selected.
Channel Monitor
NOTE - Federal Communications Commission Rules
and Regulations require that you monitor a
frequency for activity before transmitting.
To monitor the channel for activity before transmitting,
press the monitor button.
NOTE - The TX/RX indicator will glow amber if RF
activity is present. It will glow green if the
10

transmission has a CTCSS or DCS tone that
matches a tone programmed for receiving. If the
LED is not illuminated, a clear channel is present.
If enabled, the channel can be monitored for activity before
transmitting by going off-hook.
Transmit
When the channel is clear, press and hold the P-T-T bar
on the side of the microphone. Hold the microphone 1 or 2
inches from your mouth, and speak clearly and distinctly.
The LED will glow red when transmitting and should be on
continuously while the P-T-T bar is being pressed and the
radio is transmitting.
Receive
When the transmission is complete, release the P-T-T bar
to receive.
NOTE - Pressing the monitor button disables any tone
coded squelch options, if programmed.

Scan Modes
Channel Scan
Channel scan is a programmable feature that allows you to
monitor a number of channels. Your dealer will help you
define a channel scan list to be programmed into a scan
channel location (any channel, 1 - 4). Once that channel
location is selected, scan is initiated.
Normal Scan
Once the scan list is programmed, you can initiate scan.
Simply move the channel selector knob to that position,
and the radio will start to scan. The TX/RX indicator on
the front panel can be programmed to flash green as the
radio is scanning.
If a conversation is detected on any of the channels in
the scan list, the radio will stop on that channel, and
you will be able to hear the conversation. If programmed
for normal scan TX, you will be able to transmit on that
active channel during the programmable scan delay time.
The scan delay time is the amount of time the radio will
stay on that channel once activity has ceased (dealer
programmable, 4 - 7 seconds is typical). The radio will
resume scanning once the scan delay time has expired.
Going off-hook while locked on an active channel will
stop scan and allow for transmission and reception.
The radio will continue to scan when going off-hook and
not locked on an active channel. Scanning will continue
unless the channel selector knob is changed or the P-T-T
bar is pressed. 12

13
Priority Channel Scan
A single channel may be programmed as the priority
channel. The radio will constantly monitor this channel
while scanning and when the radio has stopped on an
active channel. If a call is detected on the priority channel,
the radio will automatically move to and remain on the
priority channel for as long as the priority conversation
takes place. Priority channel activity takes precedence
over all other conversations.
NOTE - Priority channel scan and look-back require that
the radio leave the active channel for a fraction
of a second (at regular intervals) to check the
priority channel for a message. Depending upon
how the radio is programmed (scan speed, etc.),
this may or may not be noticeable as breaks on
the active channel for that same fraction of a
second.
Scan Channel Delete
On occasion you may wish to temporarily delete a channel
from the scan list. To do this, simply press the monitor
button while scanning and stopped on the channel to be
deleted. This will remove that channel from the scan list
until the selector is moved from the scan list channel
position or the radio’s power is reset. When power is
restored or the scan list channel position is again selected,
the original dealer programmed scan list will be activated.

Other Programmable Scan Features
Look-Back
Any channel, when not in the scan mode, can be pro-
grammed to “look-back” at the priority channel. This
feature is ideal for those who do not need scan as defined
above but want to make sure they never miss a call on the
priority channel if another channel has been selected.
Once a look-back channel has been selected, the radio
will periodically scan the priority channel. If activity is
detected on the priority channel, the radio will move to
that channel for as long as it remains active.
CTCSS/DCS Scanning
The SM-2000 can be programmed to scan for tone. This
will help block out unwanted calls.
Normal Scan TX
A transmission is allowed only after a call is received,
depending on the programmed scan delay time. After scan
resumes and a transmission is made, the radio will sound
an alarm (two beeps) and will not allow a transmission.
Priority Scan TX
This allows a transmission after a call is received depend-
ing on programmed scan delay time. The transmission will
be made on the channel that the call was received. After
the radio resumes scanning, if a transmission is made, the
radio will transmit on the programmed priority channel.

Priority Only TX
Your radio will transmit on the priority channel when
scanning and when not stopped on an active channel. It
can also be programmed to always transmit on the priority
channel if scanning or stopped on an active channel.
Receive Only Scan
If a transmission is made at any time, the radio will sound
an alarm (two beeps) and will not allow the transmission.
Only reception is allowed.
Fuse Replacement
For protection from fire hazard, replace fuse only with
same size, type and style: 32 V, 10 amp 3AG fuse.
FCC Licensing
The Federal Communications Commission requires that the
user of this radio be properly licensed under the applicable
Part and / or Parts of the FCC Rules and Regulations.
Consult with your Maxon Dealer or contact the nearest
FCC Field Office for pertinent information related to
obtaining a license.
