Blank spaces next to an antenna number indicate that no antenna has
been detected in this position.
So the above display would indicate that five antennas are connected
to the basestation in positions 1, 2, 3, 6, and 7. There are no active
antennas in positions 4, 5, 8, 9, and 10.
There are 4 beltpacks currently connected. Beltpacks 2 and 4 occupy
the first 2 slots of antenna 3; beltpack 1 occupies the first slot of
antenna 6; and beltpack 3 occupies the first slot of antenna 7.
The display updates every 4 seconds to reflect changes in antenna
status and beltpack connections.
Rotate or push in the setup/enter knob to exit this menu.
ASSIGNING BELTPACKS TO COVERAGE AREAS
Each antenna is designed to handle five beltpacks simultaneously.
Although it can achieve this in good conditions, this may not always be
possible for a number of reasons. First, interference or propagation
problems may mean that not all antenna slots are available all the
time. Second, a beltpack constantly searches for the best antenna
signal, and may frequently switch antennas. To make this transmission
seamless, a beltpack maintains the connection to its current antenna
until it is confident that the new antenna is functioning well. Therefore,
for a short period of time during this transition, a single beltpack can
occupy slots on more than one antenna.
This means that for zones likely to need coverage for five or more
beltpacks simultaneously it is recommended that a second antenna is
installed. Similarly, for good coverage for nine or more beltpacks
simultaneously, a third antenna may be required.
CONDITIONS AFFECTING COVERAGE AREAS
The environment in which a system is located affects the coverage
area for any particular beltpack/antenna combination. The presence of
walls, floors, ceilings, trees, shrubbery, people, and numerous other
items may affect the coverage zone. Metallic objects, safety doors,
lighting equipment, and bodies of water may possibly block
transmission. These factors must be taken into consideration when
planning the installation.
