AntennaInstallation
Attach the antenna by turning clockwise into the antenna
receptacle on top of the radio.
Installing and Removing the Battery Pack
Hold the radio face down in your hand. To attach the battery
pack, pick up the pack by the sides and hold it so that the four
charging contacts are facing upward, positioned toward the
bottom. Visually locate the "up" arrows embossed inside the
radio, then place the pack onto the radio, positioning the top
of the pack to slightly cover the arrows. Using your fingertips,
ensure the pack is flush with the radio sides. The channels in
the pack will align with guides on the radio.
Slide the battery pack upward slowly. A click will verify that
the battery pack is securely positioned.
Remove the battery pack by holding the radio face down
in your hand. Slide and hold the battery latch (at the base of
radio) then gently apply pressure to move the battery pack
slightly downward. The pack will release from the radio's
guide rails. Lift the battery pack straight up and away from
the radio.
Attaching and Removing the Belt Clip
The belt clip attaches to the radio's battery pack. To attach
the belt clip, hold the clip and slide it into the recessed area
at the top of the pack. A click will verify the clip is securely
positioned. To remove the clip, press and hold the release
tab toward the clip while gently pulling the belt clip assembly
off the radio.

Battery Charging and Care
To ensure maximum performance from your radio, the battery
pack must be fully charged before initial use. For continued
performance, periodically discharge the battery completely
and then fully recharge the pack. Proper care and charging
will extend life of your battery pack.
Maxon offers two chargers for use with the SP-150 radio. Each
model is sold separately and is available through your original
purchasing Dealer.
The QPA-1135 Pedestal Charger provides a slow overnight
charge of 12-16 hours. The charger has a single well which
charges a radio with battery attached.
The QPA-1130 Desktop Charger provides quick charging in
1.5 hours and normal "slow" charging. The charger has two
wells, one accommodates a radio with battery attached; the
other is for a battery removed from the radio.
Refer to the instructions accompanying each of these Maxon
chargers for more information.
Accessory Connector
Your SP-150 radio has an accessory port located on the side
of the unit. If you do not plan to use accessories when you
initially purchase the radio, keep the protective cover plate
installed to keep dust/debris from entering the radio.

SP-150Operation
Your Maxon SP-150 can be programmed to operate in
both Trunked and Conventional modes. Each System can
be individually programmed to operate in either Trunked
or Conventional Systems. There are only a few differences
in their operation and these are detailed as follows:
Channel Monitoring
While on a Trunked System, channel monitoring is performed
automatically by the radio transceiver. In accordance with
the FCC Rules, while operating on a Conventional System,
the channel must be monitored prior to transmitting. In both
Trunked and Conventional Systems, operation may vary from
System to System. Your Maxon Dealer will be able to assist
with particular operational parameters and procedures for the
various Systems and functions.
System "Handshaking"
In a Trunked System, when the P-T-T is pressed, the red TX
indicator flashes momentarily to allow the transceiver and
System to connect properly. When the red TX indicator glows
steady, voice transmission may begin. If your Maxon Dealer
has enabled the "Clear-to-Talk" tone option, the radio will
emit a short tone signaling voice transmission may occur. In
Conventional Systems, there is no System "handshaking" and
voice transmission may start immediately upon pressing the
P-T-T.
Busy System Queuing (Dealer Programmable Option)
If enabled by your Dealer, busy System queuing will monitor
the System for activity. Once the System becomes available,
the System will automatically be accessed and held for a
period of time (determined by your Dealer), allowing you to
transmit on the System. A tone will sound and a flashing
7

yellow TX/Call LED will indicate when queuing has begun.
The tone will sound again and the LED will flash red when the
System has been acquired.
Talk-Around (Dealer Programmable Option)
Talk-around mode, if enabled by your Dealer, allows you to
bypass the System and talk from radio to radio. This is useful
when your radios are out of range of any System. Talk-around
can be enabled by pressing one of the two option buttons*
located on the side of the unit. An audible alert will sound
(if enabled) when key is pressed, indicating the radio is active
for talk-around mode.
* The option button designated to enable talk-around is
determined by your Dealer.
Transpond Mode (Dealer Programmable Option)
If transpond has been enabled by your Dealer, your radio will
automatically send (transpond) an acknowledgment to the
System indicating that your radio has received a transmission.
Power On - Volume - Power Off
Turn the radio on by rotating the off/on - volume control
clockwise. You will hear a click and (if enabled via Dealer
programming) the radio's self-test alert tones. Increase the
radio volume by continuing the clockwise rotation. To turn
the radio off, rotate the control counter-clockwise to detent.
Transmitting on a Trunked System
1) Turn the radio on and adjust the volume to desired level.
2) Select the desired System and/or Group using the
System/Group/Channel selector knob, located on top
of the unit.
3) Press and hold the P-T-T button on the side of the radio.
(If a "Busy", "Intercept" or "Ringback" tone is heard, refer
to
"Status Indicators and Audible Alert Tones"
section for
more information). 8

9
4) Listen for the "Clear-to-Talk" tone (or wait for the TX
indicator to glow steady) and begin talking. Hold the radio
1 to 2 inches from your mouth, speak clearly and distinctly
into the microphone area of the front grill.
5) Release the P-T-T button as soon as the message is com-
plete. The P-T-T button must be pressed continuously while
speaking.
Receiving on a Trunked System
1) Confirm that the radio is on and receiving power. Select the
desired System and Group.
2) When a message is received, the TX/Call indicator will glow
green.
3) Respond to a message by pressing the P-T-T button on the
side of the radio. Press the P-T-T continuously while talking
and release to listen.
Conventional Mode Operation
Your Maxon SP-150 may be programmed to operate in
Conventional modes. Conventional mode may or may
not require a Conventional repeater System. Radio to radio
communications can also be accomplished in Conventional
operation. How the Conventional mode is programmed is
determined by your Dealer.
Transmitting on a Conventional System
1) Turn the radio on and adjust the volume to desired level.
2) Select the desired channel using the System / Group /
Channel selector knob, located on top of the unit.
3) In a Conventional System it is necessary to monitor the
channel for activity before a transmission. Monitor by
pressing one of the two option buttons** located on the
side of the unit or by observing the TX / Call indicator for
a solid yellow or green color. If solid yellow or green is
observed, you must wait for the indication to leave before

a transmission can be made. ** The option button desig-
nated to enable monitor is determined by your Dealer.
4) Press and hold the P-T-T button on the side of the radio.
Hold the radio 1 to 2 inches from your mouth, speak clearly
and distinctly into the microphone area of the front grill.
5) Release the P-T-T button as soon as the message is complete.
The P-T-T button must be pressed continuously while
speaking.
Receiving on a Conventional System
1) Confirm that the radio is on and receiving power. Select the
desired channel.
2) When a message is received, the TX / Call indicator will glow
solid yellow or green (depending if CTCSS or DCS tone has
been programmed).
3) Respond to a message by pressing the P-T-T button on the
side of the radio. Press the P-T-T continuously while talking
and release to listen. If scanning modes are enabled, be sure
to respond before scanning resumes. If you do not, another
call may be received and the selected channel may have to
be changed. Scanning is indicated by flashing green TX /
Call indicator. Refer to
"Scan Modes"
section for more
information.
OptionButtons
Your SP-150 has two programmable option buttons located
on the side of the unit. These buttons can be programmed
by your Dealer to enable a number of features, including:
•Monitor: (Conventional Systems) When programmed,
pressing and holding the appropriate option button will
open the squelch of the radio, defeating the CTCSS/DCS
tone squelch and allowing you to listen for channel activity.
•Nuisance Delete: This function will allow you to temporarily
10

11
delete anunwanted channel from the scan list. Nuisance delete
can be activated only when receiving the unwanted channel.
The feature can be programmed alone on a single option
button or combined with the monitor function. Turning the
unit off and on will return the unit to the original scan list.
•Talk-around: When programmed, pressing the appropriate
option button once will activate talk-around mode. Pressing
the option button again, or rotating the channel selection knob
will disable talk-around function.
•Scan: When programmed, pressing the appropriate option
button will enable the radio's programmed scan function.
•Edit Group Scan List: When programmed, allows editing
of channels you wish to scan.
Status Indicators and Audible Alert Tones
Your SP-150 has a sophisticated microprocessor control
which provides a series of audible alert tones. Upon initial
power up, a single tone indicates that the self-test of the
microprocessor functions have been completed satisfactorily.
A series of tones may sound with any of these conditions:
•Busy System Queuing, indicates your radio has been placed
in the queuing mode and is attempting to access the System
•Low battery condition •Selecting a Channel with no
programmed frequency
(The following are all initially programmed into the radio
by your Dealer) •Attempt to transmit on a System/Channel
that is already in use when busy channel lockout has been
programmed •Call Received •Clear-to-Talk/Transmit
indicates you may begin speaking •Transmit not available
indicates you are denied transmission on that System /
Channel •Time-Out-Timer indicates you have exceeded
the maximum transmission time

To enable System Scan, press the appropriate option button
on the side of the radio. During System Scan the radio will
scan all Systems in the scan list programmed by your Dealer.
To enable Conventional Group Scan, press the appropri-
ate option button on the side of the radio. Conventional
Group Scan performs in the same manner as LTR®Manual
Group Scan with the exception that ID codes are not
required. Only those Groups enabled in the Group scan
list will be scanned.
Editing Group Scan List
As a user, you can edit your pre-programmed Group scan list
by adding or deleting Groups from the Group Scan List for a
given System. To activate scan list editing, press the appropri-
ate option button on the side of the radio. (Note: In order to
edit the Group scan list, the remaining option button must
be programmed to activate scan mode.) Upon entering the
edit scan list function, the LED located on top of the unit will

flash green four times and a beep will be heard with each LED
flash. To exit the edit scan list function, press the appropriate
option button again. The LED will flash red four times and a
beep will be heard with each LED flash.
Adding to Scan List
Once the option button has been enabled for scan list
editing, rotate the selector knob to the desired System
Group to be edited. To add this Group to the scan list,
press the option button programmed for scan. When a
Group is added, the LED will flash green two times and
a beep will sound with each flash.
Deleting from Scan List
Once the option button has been enabled for scan list
editing, rotate the selector knob to the desired System
Group to be edited. To delete this Group from the scan
list, press the option button programmed for scan. When
deleted, the LED will flash red two times and a beep will
sound with each flash.
Note: Priority and Priority Look Back Groups cannot be edited
from the scan list.
Priority Look Back
If Dealer-programmed, your SP-150 will "look back" to the
programmed priority channel if the selector knob is positioned
on a System / Channel other than the programmed priority
channel.
Conventional Scanning
Your SP-150 can be programmed for one of six different scan
types, as determined by your Dealer. To enable scan, press the
appropriate option button on the side of the radio. Only those
channel Groups pre-programmed by your Dealer will be in the
scan list. 14

Talk Back Scan
RX: The radio only receives calls from its selected channel
and channels in the selected channel scan list.
TX: The radio will transmit on the selected channel if a call
is not received. If a scanned call is received, the radio will
transmit on that scanned channel until scanning resumes.
RX Only/TX Disable
RX: The radio will only receive calls on the selected
channel and channels in the selected channel scan list.
TX: No transmissions are allowed. If transmission is
attempted, an alert will sound.
Priority TX Scan
RX: The radio will receive calls from its selected channel
and channels in the selected channels scan list.
TX: All transmissions will be made on the programmed
priority channel, no matter where the selector knob is
positioned. Transmissions can also be made only on
those scanned calls which have been received before
scanning resumes.
Priority Only TX
RX: The radio will receive calls from its selected channel
and channels in the selected channel scan list.
TX: All transmissions will be made on the programmed
priority channel, no matter where the selector knob isposi-
tioned. No transmissions will be allowed on scanned calls.
Priority Look Back Scan
RX: The radio will receive calls on its selected and priority
channel. While the radio is receiving a call on its selected
