Unpacking
When ready for installation, carefully unpack your G3 kit (p/n 023 6000-101) shipping carton and identify each item as listed below:
• One G3
• Installation mounting bracket
• Power cable – 22 feet (6.7 meters)
• Small parts kit
If damage has occurred to the equipment during shipment, file a claim with the carrier immediately.
2. Installation
2.1
Planning the Installation
2.1.1 Overview
To ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimum
position for G3 and its antennas as well as the routing of all associated cabling and wiring.
2.1.2 Location
Often, installations in cars are done in the trunk, underneath the back window ledge or on the trunk floor.
In vans and small trucks, it is usually done in the back of the vehicle. In large vehicles, it is often done in
the front cabin.
Be sure to place the G3 unit in such a way that:
• The LEDs can be seen (as an aid in troubleshooting)
• Access to the antenna connectors is possible without removing the unit
• Sufficient air may flow around the unit to provide adequate cooling
G3 is not fully waterproof, therefore it should be mounted sufficiently away from an opened trunk lid or
opened tailgate, windows or doors to avoid exposure to rain and/or snow. It also minimizes the chance
that material can be accidentally thrown on the unit or of someone bumping against it.
2.1.3 Cable Path
Try to route the cables away from locations where they would be exposed to heat (exhaust pipes, mufflers, tailpipes, etc.), battery acid, sharp edges, mechanical damage or where they would be a nuisance to
automobile mechanics, the driver or the passengers.
Keep wiring away from automotive computer modules, other electronic modules and ignition circuits to
help prevent interference between these components and radio equipment.
Try using existing holes in firewall and trunk wall and the channels above and below or beneath the
doors, channels through doors and window columns that are convenient to run cables and wires.
Whenever possible, install conduit in which to run the cables.

2.2
Warnings
Before starting installation, review all of the following warnings.
2.2.1 RF Radiation warning
Recommended safety guidelines for the human exposure to radio frequency electromagnetic energy are
contained in the Canadian Safety Code 6 and the Federal Communications Commission (FCC) Bulletin
65. Proper installation of the transceiver antenna of G3 as summarized in section 2.5 will result in user
exposure substantially below the recommended limits for the general public.
Qualified personnel must do all antenna installations. See paragraph 2.5.2 for recommended antenna
positioning.
Transmissions when persons or animals outside the vehicle are within two feet of the antenna may result
in radio energy radiation burns or related injuries.
2.2.2 Interference with vehicular electronics
Certain vehicle electronic devices may be prone to malfunction due to lack of protection from radio frequency energy present when transmitting.
It includes, and is not limited to:
• Electronic fuel injection systems
• Electronic anti-skid braking systems
• Electronic cruise control systems
If the installation vehicle contains such equipment, consult the dealer for the make of vehicle and enlist
his aid in determining if such electronic circuits will perform normally when the radio is transmitting.
2.2.3 Secure mounting
For vehicle occupant(s) safety, mount G3 securely so that the unit will not break loose in case of an accident or violent maneuvers.
2.2.4 Explosive environments
Operation of vehicular radio transmitters in explosive environments may be hazardous and conventional
safety precautions must prevail. These include and are not limited to:
• Transmitting while fuelling the vehicle. Do not carry fuel containers in the same compartment as
G3.
• Dynamite blasting caps may explode when transmitting radio operation takes place within 500
feet. Always obey the “Turn Off Two-Way Radios” signs posted at sites where dynamite is
being used.
If transporting blasting caps:
a) Carry the blasting caps in an appropriate metal container having a soft cushioning lining.
b) Suppress transmissions whenever the blasting caps container is being loaded or unloaded into or
from the vehicle.
Check applicable local bylaws.
2.2.5 Installation in vehicles powered by liquefied gas.
G3 installations in vehicles powered by liquefied petroleum gas with the LP-gas container in the trunk or
other sealed-off space within the interior of the vehicle must conform to the National Fire Protection Association Standard NFPA 58 which requires:
• Space containing radio equipment shall be isolated by a seal from the space containing the LPgas container and its fittings.
122 20130-005
10
G3 Installation Guide
•
Outside filling connections shall be used for the LP-gas container.
The LP-gas container space shall be vented to the outside of the vehicle.
2.3
Physical Unit
2.3.1 Recommended tools and supplies
•
•
•
•
•
Electric drill for mounting holes
Hammer and center punch
Tie-wraps
Drills and circle cutters as needed according the size of screws (or nuts and bolts) used.
In-line “Power meter” capable of measuring forward and reflected power at the operating frequency of the radio.
2.3.2 Physical mounting of G3
a) Start by running all the cables (DC power, PC RS-232 as well as all antennas cabling) prior to
mounting G3 to assure the feasibility of the planned cable routing.
b) Be sure to leave sufficient slack in each cable so the G3 may be removed from the mounting
bracket for servicing with the power applied and the antenna attached.
c) G3 is ready for installation.
Cautions:
• When drilling mounting holes, be careful to avoid damaging some vital part of the vehicle such as fuel tanks, transmission housing etc. Always check how far the mounting
screws extend below the mounting surface prior to installation.
• Use of drill bit stops is highly recommended.
• After drilling, remove all metal shavings before installing screws.
• Do not overtighten self-tapping screws.
1. Once you have found a suitable mounting position for G3, hold the unit and the unattached mounting
bracket in the proposed mounting position and check that there is clearance behind the unit for the
heatsink, cables, etc. Check that the position provides a large enough flat surface that the bracket will
not be distorted when installed.

2. Using the installation bracket as a template, mark the four locations for drilling (see Figure 1). Again,
ensure that drilling at the selected points is safe and will not cause damage.
3. Indent the drilling positions with a center punch.
4. Drill holes sized for the self-tapping screws or for the nuts, bolts and lock washers used.
Caution: Slightly reduce the size of the drilled holes when using self-tapping screws in thin metal.

Figure 2 - Bracket installation
5. Install the bracket without distorting (see Figure 2).
6. Securely mount G3 to the installed bracket using the four supplied 8x40 black machine screws.
7. Drill any additional holes as required for routing all cables and fit holes with suitable grommets or
bushings whenever required.
2.4
Electrical installation
2.4.1 Electrical requirements
G3 is designed to operate from a 13.8Vdc nominal car battery (negative ground) and requires currents up
to 12.0A. It will tolerate a supply voltage range of 10.9 volts to 16.3 volts.
In vehicles with a 24 VDC electrical system (mostly in trucks), it is essential to provide a suitably rated
24/12 VDC converter to isolate the unit from the battery and protect it against excessive voltage.
Warnings:
Always disconnect G3’s DC power lead before connecting a second battery, using power from
another vehicle or power boosting (e.g. when “jump starting” the vehicle).
2.4.2 Routing of power cable
1. Start by disconnecting the vehicle’s battery unless specifically prohibited from doing so by the
customer, vehicle manufacturer, agent or supplier.
Note:
In this event, exercise extreme caution throughout the installation and fit the fuse only
when the installation is complete.
2. The 22 feet (6.7 meters) long power cable consists of three wires attached to a Packard Electric
“Weather-Pack” connector (DC power Connector, see Figure 3).

G3 Installation Guide
3. Place this connector at G3’s radio power input location. Do not connect at this time. See paragraph
2.6, “Completing the physical install ation”.
4. Carefully route both the B and the C wires to where the in-line fuse holder will be installed, usually
as close to the vehicle’s battery as practicable. Ensure that leads do not chafe on any metal part(s).
Secure the wires at several locations along their length.
Caution:
Use proper crimping tool. Common pliers are NOT acceptable.
Warning:
The DC Power lead must be unswitched
5. Insert the negative (blue) lead into one of the appropriate connector lug and crimp solidly to force the
metal contacts onto the wires.
6. Repeat the step above for connecting the red DC power lead.
7. Attach the positive lead at the battery positive terminal. Attach the negative wire at the vehicle end of
the battery ground cable.
If the negative cable is connected directly to the battery negative terminal, it should be fused in
case of failure of the vehicle’s ground cable.
Ensure tight and secure connections.
8. Fasten the fuse holder and leads.
9. Carefully route the “A” wire to where the connection will be made for switch sen sing.
• Connect to “Ignition” if you wish to have G3 turning ON and OFF dependent on the vehicle’s i gnition key.
• Connect to “Accessory” if you wish G3 to be available when the engine is not running, but still
dependent on the ignition key.
• Connect to a user-supplied control switch.
• In installations equipped with a “ChargeGuard ”, connect to the controlled-side of the Cha rgeGuard (remembering that the DC Power lead must NOT be switched).
10. Make appropriate connections.
Cautions:
Where scraping to bare metal was required, and at the battery posts where wire ends and lugs
may be exposed, apply anti-corrosion compound.
Insert the fuse only when installation is complete and ready to test.
11. At the G3 position, neatly coil cable slack and attach securely.
2.5
Antenna
The main transmitter antenna must be vehicle-mounted to provide a separation distance of 50 cm or more
from all persons and the antenna gain must not exceed 5dBi (with a 1.6dB cable loss).
2.5.1 Recommended tools and supplies
•
•
circle cutter, hole saw or socket punch for antenna
Mini-UHF Crimp tool
122 20130-005

G3 Installation Guide
2.5.2 Planning
Referring to Figure 4, G3 commonly uses three separate antennas:
• “T” - Main transceiver Constraints are the limit of 50 cm (see section 2.5 above) and omni-directional factors
•
“R” - Auxiliary receiver –
Constraints are the receiver spacing of at least 5/8 λ (wavelength) from transceiver antenna and
omni-directional requirements
•
“G” - Global Positioning System (GPS)
Constraints are TX spacing of at least 24-in/60.96 cm from all transmitting antennas and a clear view
of the sky.

Figure 4 - Antenna spacing
For the optimum antenna spacing at the frequency you are using, consult System Engineering.
For installation of ground-plane dependent antennas, the center of the metal surface used for mounting is
preferable for best omni-directional pattern. For ground-plane independent antennas, installation may be
close to the edges of the surface.
Install the antennas in one of the following positions:
• Most preferred for all antennas: centerline of roof. For transmitter antenna, it is the ONLY acceptable position.
• Less preferred for receiver antenna: trunk lid, providing distance to transmitting antenna is respected
whether lid is opened or closed.
• Much less preferred, but permissible for receiver antenna: left or right rear fenders, just in back of
rear window
• Least preferred, but permissible for receiver antenna: left or right front fenders, ahead of windshield
Proximity to other vehicle-mounted antennas may cause mutual interference especially at higher frequencies.

G3 Installation Guide
2.5.3 Antenna Installation
1. Route good quality 50-ohm coaxial cables (e.g. RG-223) from each of the selected antenna positions
to the position where the G3 unit is mounted.
2. Terminate the end at each of the antenna positions with the appropriate connector for the antenna
used and make the connection.
3. At the G3 position, cut the three cables to length and terminate with the appropriate plug. For the
transceiver and the auxiliary cables, use a Mini-UHF crimp plug using an appropriate crimping tool.
For the GPS, use a SMA connector.
4. Positively identify the transceiver mini-UHF plug and connect to the left rear of G3.
5. Positively identify the auxiliary receiver mini-UHF plug and connect to the front left of G3 to the RX
position.
6. Connect the SMA connector to the GPS* position below the auxiliary connector position.
7. Do not skip this last step, trust us; it is an important one. To complete the installation, tie-wrap together the auxiliary and the GPS antenna cables at a point about two inches in front of the unit. It will
be much easier hereafter to correctly identify which mini-UHF plug goes where. You DO NOT want
to cross the auxiliary plug with the transceiver plug.
2.6. Completing the physical Installation.
To complete the physical installation and prior to testing G3:
•
Connect DC Power cable’s connector to G3’s until you hear a click as the two parts snap t ogether.
• Re-check that all other connections are secure (antennas, PC, etc.)
• Switch vehicle ignition ON.
You are now ready to check for normal operation and to run the Radio Installation Software (WinRIS)
program for testing or trouble-shooting.
2.7. Checking out Normal operation
Check that the vehicle ignition is ON.
1. Check for proper operation of the G3’s LEDs as per Table 1 on page 17.
2. Using the WinRIS program and an in-line wattmeter, check forward & reverse power to confirm
main antenna installation (as per section 4).
3. Using WinRIS, check the RF Data Link with a base station that can be heard (see section 4.3.3).
If user application and its base station are available, test the installation by going through a normal sequence of transmitting and receiving messages.

DCD – from G3, normally asserted
RXD – data from G3
TXD – data to G3
DTR – to G3, handshaking
Ground
DSR – from G3, tied to VCC through current limiting resistor
RTS - to G3, handshaking
CTS – from G3, handshaking
AUX - auxiliary input to G3, (for port 2: “Officer requires assistance” Alarm input)
It may be activated by (normally open) dry contact pull-up to the port’s DSR output. It may also tolerate
user pull-up to external +12 VDC (car battery), but an isolated dry contact is preferred due to the risk of
noise-related false alarms caused by the vehicle’s electrical system.
A +3 to +12 V signal at this pin will send a DMP “x” (On) message to the base.
An open or ground signal will send a DMP “y” (Off) message.
Messages are only sent when a signal transition occurs.
See Appendix “A” on page 24 for further details.

Equipment Required
13.8 VDC (nominal) car battery, or
13.8 VDC/20A regulated power supply (In the case the unit is not installed in a vehicle)
In-line watt meter (50W range)
Radio service monitor (IFR or equivalent).
Cable with mini-UHF male connector to connect G3 to the service monitor.
WinRIS version 4.0 or later*
Basic Tests
Recommended checks:
1. Transmit and Reverse power output
2. Carrier frequency error
3. Frequency deviation
4. Receivers RSSI Check
5. RF Data Link test between a Gemini and a base station.
6. GPS test (not required on G3 Lite model).
- For checks 1 to 5, refer to Table 4 – Test Checklist below.
- For check 6, refer to paragraph 4.3.2 - GPS Test.
Important note: Before proceeding make sure that the service monitor has been recently
calibrated and has warmed up for at least the time specified by its manufacturer.
Some reported frequency and deviation problems have actually been erroneous indications from
service monitors that have not adequately warmed up. This is particularly likely when field
service is done during winter months

4.3.2 GPS Test
About three minutes after ignition is turned-on, the PWR LED on the G3 front panel should flash
in amber color at the rate of one pulse per second. This indicates that the GPS has acquired the
sky position of a sufficient number of satellites to arrive at a ground position solution.
If the GPS has a good view of the sky and still has not generated any position solution within
three minutes (it may take up to 10 minutes or more if the sky view is partially blocked.), the
following trouble-shooting procedures should be undertaken to isolate the fault:
1) Disconnect the GPS antenna cable connector from the Gemini radio and check for + 5 VDC
on the center pin of the GPS antenna connector on the radio using a Digital voltmeter (DVM).
If the voltage is present, do not reconnect the cable and proceed to step 2.
2) With the DVM, measure resistance between the shell and the center conductor of the GPS cable, resistance should be between 100 and 300 Ohms, if it measures open or short circuit the
GPS antenna is either a passive antenna which is the WRONG type, or a defective active antenna, replace with a known good active antenna.
3) Connect the new antenna to Gemini and wait about three minutes for the POSITION
ACQUIRED indicator to start flashing on G3, if not, the Gemini radio or its GPS receiver is
defective.
Lit green and flashing amber for the 800MHz & 900MHz models under transmitter duty cycle limit.

4.3.3 RF Data Link Test
A link test between a mobile and a known base station can be done using the WinRIS "Address"
and "Send" functions. The “Address” and “Device” fields, the “Send” button and the “Chat”
message screen are used to send messages to specific mobile or base or to carry out RF test. Start
by entering the address of the mobile (or base station) you wish to send a test message to or test:
1- Specify the address:
Addresses may be entered by typing directly in the “Address ” field in two ways:
- Numerically, the valid address range is 1-126.
- As an “Alpha-Mapped-Nibble” (AMN) address , consisting of upper case letters in the
range A-P. The valid address range is A to GN.
- The base address is usually: 1.
- The program may display one of the following messages on the status bar:
- For Paragon products:
“address is not in AMN or number format”
- For mobile products:
“address is not in the range A – GN”
In either case, check that the address entered is within the acceptable range, is of a valid format, and correctly typed.
2- Enter the Device number for mobile (or base station).
3- Press the Send button.
The Chat window reports “Sent to xx mobile” (where xx is mobile name).
If test is successful:
Status line reports “Delivery confirmed.
If test unsuccessful:
Chat window reports “Waiting”,
Then the Status line reports “Delivery Failed”.
