FCC Licensing Information
RITRON SPX Series professional two-way radios operate on radio frequencies that are regulated by the
Federal Communications Commission (FCC). In order to transmit on these frequencies, you are
required to have a license issued by the FCC. Application is made on FCC Forms 600 and 159.
Question regarding FCC license; contact the FCC at:
1-888-CALL-FCC
1-888-225-5322
Or: http://www.fcc.gov
Changes or modifications not expressly approved by Ritron, Inc. may void the user’s authority granted by
the FCC to operate this radio and should not be made. To comply with FCC requirements, transmitter
adjustments should be made only by or under the supervision of a person certified as technically qualified
to perform transmitter maintenance and repairs in the private land mobile and fixed services as certified
by an organization representative of the user of those services. Replacement of any transmitter
component (crystal, semiconductor, etc.) not authorized by the FCC equipment authorization for this radio

prohibited.
Safety and General Information
RF Operational Characteristics
Your radio contains a transmitter and a receiver. When it is ON, it receives and transmits radio
frequency (RF) energy. The SPX-200 VHF radios operate in the frequency range of 136-174 MHz, the
SPX-400 UHF radios operate in the frequency range of 400-470 MHz. When you communicate with the
SPX-200, the output power level is 1-5 watts, and with the SPX-400, the output power level is 1-4 watts
EXPOSURE TO RADIO FREQUENCY ENERGY
The SPX Series handheld radios generate RF electromagnetic energy during transmit mode. The
transmit mode is active when the PTT switch is depressed. This radio is designed for, and classified as,
“Occupational Use Only”, meaning that it must be used only during the course of employment by
individuals who are aware of the hazards and the ways to minimize such hazards. This series of radios
is NOT intended for use by the “General Population” in an uncontrolled environment.
When used as directed, this series of radios is designed to comply with the FCC’s RF exposure limits for
“Occupational Use Only”. In addition, they are designed to comply with the following Standards and
Guidelines:
• FCC OET Bulletin 65, Edition 97-01, Supplement C, Evaluating Compliance with FCC
Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
• American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels with
Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
• American National Standards Institute (C95.3-1992), IEEE Recommended Practice for the
Measurement of Potentially Hazardous Electromagnetic Fields-RF and Microwave.
To ensure that exposure to RF electromagnetic energy is within the FCC allowable limits for occupational
use, always adhere to the following guidelines:
• Use only the antenna(s) available from RITRON for these models. DO NOT attempt to
substitute any other antenna. DO NOT operate the radio without an antenna.
• Keep talk times as short and infrequent as possible. DO NOT depress the PTT button when not
actually wishing to transmit. These radios are equipped with an internal timer to limit
continuous transmit times. DO NOT exceed a 50% transmit duty cycle.
• When transmitting, hold the radio in front of the mouth at a distance of at least 4 inches. DO
NOT hold the radio in such a manner that the antenna is next to, or touching, exposed parts of
the body, especially the face or eyes while transmitting.
• In belt mounted applications, when transmitting, remove the radio from the belt and hold away
from the body at least 4 inches.

• When using external headset accessories, hold the unit away from the body at least 4 inches
while transmitting.
• DO NOT allow children to operate the radio.
Label (on the radio)
This radio complies with the FCC RF exposure
limits for Occupational Use Only.
Antenna Care
Use only the supplied or an approved replacement antenna. Unauthorized antennas, modifications,
or attachments could damage the radio and may violate FCC regulations.
Do not hold the antenna when the radio is “IN USE.” Holding the antenna affects the effective range.
Two-way Radio Operation
When using your radio as a traditional two-way radio, hold the radio in a vertical position with the
microphone two to three inches (5.0 to 7.5 cm.) away from the lips.
Approved Accessories
The following accessories can be used with the SPX Series portable.
1. RSM-3X Speaker/Microphone
2. AFS-150 Low Profile VHF antenna (SPX-200)
3. AFS-450 Low Profile UHF antenna (SPX-400)
Medical Devices
Pacemakers
The Advanced Medical Technology Association recommends that a minimum separation of 6 inches (15
centimeters) be maintained between a handheld wireless radio and a pacemaker. These
recommendations are consistent with the independent research by, and recommendations of the U.S.
Food and Drug Administration.
Persons with pacemakers should:
• ALWAYS keep the radio more than six inches (15 centimeters) from their pacemaker when the radio is
turned ON.
•DO not carry the radio in the breast pocket.
• Use the ear opposite the pacemaker to minimize the potential for interference.
• Turn the radio OFF immediately if you have any reason to suspect that interference is taking place.
Hearing Aids
Some wireless radios may interfere with some hearing aids. In the event of such interference, you may
want to consult your hearing aid manufacturer to discuss alternatives.
Other Medical Devices
If you use any other personal medical device, consult the manufacturer of your device to determine if it is
adequately shielded from RF energy. Your physician may be able to assist you in obtaining this
information.
Safety and General Use While Driving
Check the laws and regulations on the use of radios in the area where you drive.
Always obey them. When using your radio while driving, please:
• Give full attention to the driving on the road.
• Use hands-free operation
• Pull off the road and park before making or answering a call if driving.

Operational Warnings
For Vehicles with an Air Bag
Do not place a portable radio in the area over an air bag or in the air bag deployment area. Air bags
inflate with great force. If a portable radio is placed in the air bag deployment area and the air bag inflates,
the radio may be propelled with great force and cause serious injury to occupants of the vehicle.
Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive atmosphere, unless it is a radio
type especially qualified for use in such areas as “Intrinsically Safe.”
Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive atmosphere
can cause an explosion or fire resulting in bodily injury or even death.
Note: The areas with potentially explosive atmospheres referred to above include fueling areas such as
below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains
chemicals or particles, such as grain, dust or metal powders, and any other area where you would
normally be advised to turn off your vehicle engine. Areas with potentially explosive atmospheres are
often but not always posted.
Save these Instructions
1. Do not expose the charger to rain or snow.
2. Do not operate the charger if it has received a sharp blow, or has been dropped or damaged in any
way.
3. Do not disassemble the charger if it has received a sharp blow, or has been dropped or damaged in
any way.

PC Programmer
The following is a list of features that are PC programmable.
1. VOX
Internal Voice Operated Transmit allows you to operate in hands-free mode without pressing PTT.
When the VOX feature is enabled, the VOX ICON appears on LCD with “VOX LEVEL XX”. The
sensitivity level can be selected between 1(very sensitive) and 15 (less sensitive).
2. DTMF ANI
Once one of the “Hoy Keys” is selected for ANI operation, pressing that button will automatically
cause the radio to transmit the programmed ANI sequence up to XX characters.
3. 5-Tone ANI
Once one of the “Hoy Keys” is selected for 5-Tone ANI operation, pressing that button will
automatically cause the radio to transmit the programmed 5-Tone ANI sequence.
4. Scanning
Scan allows you to monitor other channels. When the radio detects activity, it stops scanning and
locks in on the active Channel. This allows you to talk and listen to the person transmitting without
changing channels.
Once one of the “Hoy Keys” is selected for SCAN operation, pressing that button will automatically
cause the radio to scan all channels programmed for scan.
Priority scan channel
One channel can be selected as a priority channel. When scanning or receiving, if there is
activity on the priority channel, the radio will automatically go to the priority channel until the
activity is finished.
5. TX power (1W or 4W/5W) per channel
TX output power can be to Low 1W or High 4W(UHF) or 5W(VHF). You can select low to extend
battery life or high to extend communication range.
6. Busy channel lockout
BCLO prevents users from transmitting if any activity is detected on the channel. If selected “BC” will
appear on the LCD.
7. Power Saving Control
If after a predetermined time the transceiver has not entered either transmit or receive mode, it will

automatically go into power save mode. This feature will further increase your duty cycle.
OFF: Power Saver is disabled
PSC-NORM: Normal mode
PSC-ENH: Enhance mode
8. Talk around
Once one of the “Hoy Keys” is selected for Talk-Around operation, pressing that button will
automatically cause the radio to transmit on the transmit frequency of the repeater system you are
using. A ”T” will appear on the LCD.
9. Squelch Level
You can program which levels you wish to set appropriate squelch level.
LEVEL 00: Loose, LEVEL 8: Standard, LEVEL 15: Tight
10. Large Font Display
Font size for the LCD can programmed or either “Small” or “Large”.
11. Select RX/TX Tone
QC, DQC, or NONE sub-audible sub-tones may be programmed for each channel.

2. Low Battery Warning & Display
When the available capacity falls below 10%, the Battery ICON will flash with a warning sound. At
this time it is recommended that you either change or re-charge the battery pack as early as
possible. (Battery ICON indicates battery capacity)
3. Time–Out Timer (TOT)
This feature limits the amount of time you can continuously transmit on a channel. The time range
is programmable from 0~250 seconds. There will be a short pre–alert warning tone 4 seconds
prior to the end of the transmission, the transmission is then terminated and there will be a
constant alert tone until you release the PTT Button.
