Gemini/PD Installation Guide
4
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 nor-
mally when the radio is transmitting.
2.2.3 Secure
mounting
For vehicle occupant(s) safety, mount
Gemini
PD
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 Gemini
PD
.
-
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.
Gemini
PD
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 As-
sociation Standard NFPA 58 which re-
quires:
-
Space containing radio equipment shall
be isolated by a seal from the space
containing the LP-gas container and its
fittings.
-
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 ac-
cording the size of screws (or nuts and
bolts) used.
•
In-line “Power meter” capable of meas-
uring forward and reflected power at the
operating frequency of the radio.
2.3.2 Physical mounting of
Gemini
PD
Start by running all the cables (DC power,
PC RS-232 as well as all antennas cabling)
prior to mounting Gemini
PD
to assure the
feasibility of the planned cable routing. Be
sure to leave sufficient slack in each cable
so the Gemini
PD
may be removed from the
mounting bracket for servicing with the
power applied and the antenna attached.
Gemini
PD
is ready for installation.
Cautions:
•
When drilling mounting
holes, be careful to avoid dam-
aging some vital part of the ve-
hicle such as fuel tanks, trans-
mission housing etc. Always
check how far the mounting
screws extend below the
mounting surface prior to in-
stallation.
•
Use of drill
bit stops is
highly recommended.
