According to limitations established by the radio-modules Grants, antenna(s) gain should also be limited. For cellular antenna, in mobile
and fixed operating configurations the antenna gain, including cable loss, must not exceed 2 dBi at 700 MHz, 5.15 dBi at 850 MHz, 2.15
dBi at 1700 MHz and 1900 MHz and 4.2 dBi at 2600 MHz for satisfying RF exposure compliance. The antenna(s) must be installed such
that a minimum separation distance of 33cm is maintained between the radiator (antenna) and all persons at all times.
Specific conditions by FCC and IC must be observed by any integrator in order to comply with the specific restrictions of the Grants for all
the radios.
CONDITIONS
▪ Antenna(s) to user distance of all transmitters listed above is 33 cm or larger.
5. Installation
5.1. Choosing a location
The device should be installed by authorized trained maintenance operators in a restricted area.
Choose a location for owa450 which allows for convenient routing and connection of the antenna and interface cables, and which has
access to power source, and status LED’s. When selecting a mounting location avoid the following hazards:
▪ Excessive heat or cold.
▪ High vibration areas.
▪ Corrosive fluids and gases.
▪ Direct exposure to solar radiation.
▪ Do not obstruct drivers view or impede operation, when mounted in vehicles.
5.2. Inserting the microSIM Card, microSD card and Optional Battery.
owa450 microSIM Card holder is a push-push connector type. To access the microSIM compartment, first unmount the 2 screws Torx 8 of
the back cover.
Then, insert SIM card with contacts facing downwards as in the figure below.
Same procedure for inserting the microSD card in its compartment and for connecting/disconnecting optional Battery using its one-position
connector.
