Introduction
This Manual covers the Odyssey 2000 800MHz Mobile Radio for Digital
Channel/Multicarrier Architecture, DCMA, with Trunking. The unit is a compact two-
way radio transceiver featuring digital technology developed by ComSpace
Corporation, that greatly increases the traffic carrying capabilities of the radio network
while at the same time improving the quality of communications. The principle features
are:
1) Digital Modulation with DCMAtechnology.
2) Digital Trunking (Direct Frequency Assignment) compatible with E.F. Johnson LTR
network protocols.
3) Enhanced voice quality via AMBE+vocoder.
THANK YOU!
We believe that this “Technology development for the wireless future” will be an easy-to-
use transceiver that will provide dependable communications to allow peak operating
efficiency. We are grateful you chose ComSpace Corporation for your professional
mobile radio applications and believe that you will be pleased with the quality and
features of our products.

ONE OR MORE OF THE FOLLOWING STATEMENTS MAY BE APPLICABLE:
FCC WARNING
This equipment generates or uses radio frequency energy. Changes or modifications to
this equipment may cause harmful interference unless the modifications are expressly
approved in the Operator’s Manual. The user could lose the authority to operate this
equipment if an unauthorized change or modification is made.
INFORMATION TO DIGITAL DEVICE USER REQUIRED BY THE FCC
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can generate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that the interference will not
occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the
following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment to an outlet on a circuit breaker different from that to which
the receiver is connected.
•Consult the dealer for technical assistance.
NOTICES TO THE USER
•GOVERNMENT LAW PROHIBITS THE OPERATION OF UNLICENSED
RADIO TRANSMITTERS WITHIN THE TERRITORIES UNDER
GOVERNMENT CONTROL.
•ILLEGAL OPERATION IS PUNISHABLE BY FINE OR IMPRISONMENT
OR BOTH.
•REFER SERVICE TO QUALIFIED TECHNICIANS ONLY.

Instruction Manual Page 6of 25
SAFETY:
It is important that the operator is aware of, and understands, hazards common to the
operation of any transceiver.
WARNINGS (INJURY FROM RADIO FREQUENCY TRANSMISSIONS):
•DO NOT OPERATE the mobile radio when someone outside the vehicle is within
15 inches (39 cms) of the antenna. For example, DO NOT OPERATE the mobile
transceiver when someone is either touching the antenna or in proximity as specified
above to avoid the possibility of radio frequency burns or related physical injury.
•This radio is NOT approved for use by the general population in an uncontrolled
environment. This radio is restricted to occupational use, work related operations
only where the radio operator must have the knowledge to control the exposure
conditions of passengers and bystanders by maintaining the minimum separation
distance of 15 inches (39 cms).
•The mobile must be used in vehicle-mount configurations with a maximum operating
duty cycle not exceeding 50%.
•Failure to observe the above warnings will result in exceeding the FCC RF exposure
limits.
•EXPLOSIVE ATMOSPHERES (GASES, DUST, FUMES, etc.): Turn OFF your
transceiver while taking on fuel or while parked in gasoline service stations. Do not
carry spare fuel containers in the trunk or your vehicle if your transceiver is mounted
in the trunk area.
•DYNAMITE BLASTING CAPS: Operating the transceiver within 500 feet of
dynamite blasting caps may cause them to explode. Turn OFF your transceiver when
in an area where blasting is in progress, or where “TURN OFF TWO-WAY RADIO”
signs have been posted. If you are transporting blasting caps in your vehicle, make
sure they are carried in a closed metal box with a padded interior. Do not transmit
while the caps are being placed into or removed from the container.
ANTENNA AND INSTALLATION CONSIDERATIONS:
•All equipment must be properly installed in accordance with ComSpace installation
instructions.
•To assure compliance with United Stated FCC regulations on RF exposure, the user
of the equipment must position the antenna in such a way to maintain a separation of
at least 15 inches (39 cms) between the antenna and the body of any user or nearby
person. For example, for rear deck trunk and window installations, the antenna must
be located at least 15 inches (39 cms) away from passengers and any bystanders.
•Ensure that the antenna is properly installed external to the vehicle and in accordance
with the requirements of the antenna manufacturer/supplier.
•Use only the supplied or an approved antenna. Unauthorized antennas, modifications,
or attachments could impair call quality, damage the equipment, or result in violation
of the ICNRP or the FCC.

PRECAUTIONS
CAUTION:
Please observe the following precautions to prevent personal injury, fire, and
transceiver damage.
•DO NOT transmit for more than 50% of total radio use time (50% duty cycle).
Transmitting more than 50% of the time can cause FCC RF exposure compliance
requirements to be exceeded. The radio is transmitting when the front panel of the
radio displays the word “TRANSMIT”. The radio is placed in transmit mode by
pressing the Push-to-Talk (PTT) button on the radio’s microphone and receiving a
grant to transmit from the repeater.
•DO NOT attempt to configure the transceiver while driving; it is dangerous.
•DO NOT modify the transceiver for any reason.
•DO NOT expose the transceiver to long periods of direct sunlight, nor place it near
heating appliances.
•DO NOT place the transceiver in excessively dusty, humid or wet areas, or on
unstable surfaces.
•If an abnormal odor or smoke is detected coming from the transceiver, turn OFF the
power immediately. If the unit does not turn OFF, remove the power source. Contact
your ComSpace dealer.
