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 Gemini

PD+

 products 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 section 2.5 for recommended 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 fre-
quency 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 Gemini

PD+

 radiomodems securely so that the unit will not break

loose in case of violent maneuvers or an accident.

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+

 radiomodems installation 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 Na-
tional Fire Protection Association Standard NFPA 58 which requires:

 

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.
