The operation of this transmitter must satisfy the requirements of
Occupational/Controlled Exposure Environment, for work-related use. Transmit
only when person(s) are at least the minimum distance from the properly
installed, externally mounted antenna.
2.7 Power Switch
Unless otherwise noted in the DWC shipping documents, the station is shipped
with the internal batteries factory-connected. The rear panel power switch is set
to the “OFF” (down) position. Prior to installing the unit the power switch may be
set to the “ON” (up) position to verify that the unit is functional, however care
must be taken to not depress the red transmit button on the front panel, or “key
up” an i2way mobile or portable on the station’s operating frequency in the
immediate vicinity of the unit unless a suitable 50 ohm antenna load is attached
to the transmitter output “Type N” connector on the rear panel.
2.8 Antenna System
The station needs an antenna system, and the design of such system may greatly
vary from installation to installation. If maximum coverage is desired, a high
quality antenna system, consisting of two or more separate antennas for receive
and transmit, along with high quality antenna filtering, is suggested. If the
coverage requirements are modest, a lower quality antenna system is acceptable.
Some “campus” systems may utilize “radiating” cable in order to provide service
in difficult buildings. Since antenna systems vary immensely, you should consult
an engineering professional familiar with the design of mobile antenna systems
prior to installing this station.
2.9 Grounding
Connection of the station to a good quality ground is necessary for safety and to
protect the station from the environment. If you install more that one DB-1000
station, each station should be independently grounded. A 6-32 “grounding
screw” is provided at the rear of each base station. It is painted green for
identification. Lightning and surge protection should be installed on each antenna
transmission line and grounded where the transmission line enters the building.
Polyphaser devices are one suitable product. The transmission line should be
grounded to the tower and at the building entrance pursuant to normal industry
procedures.
