Select RF channel
On 5GHz UNII RF bands, there is a separate definition and guideline for RF band to be used in indoor
environments. On the Base Station or GCM, select ‘Indoor’ if you use the system in any indoor environments.
When using the system at any outdoor environments, ‘Outdoor’ should mandatorily be selected. Selecting
'Indoor' allows the use of ‘Indoor’ and ‘Outdoor’ RF bands. Refer to the Table above for usable RF bands of
indoor and outdoor in each region.
Note:
Upon the change of the setting of indoor or outdoor, the Base Station should be rebooted.
Turn off Base Station radio transmission.
Select TX Off if the Base Station does not need to transmit and receive radio signals.
Note:
Beltpack pairing is not available in TX Off mode. Change the mode to TX On for the Beltpack pairing.
Attenuate radio transmission power
If it is required to attenuate the radio wave to avoid RF interference, use GCM to attenuate radio transmission power
of the Antennas.
Precautions to install multiple Antennas
When installing multiple Antennas, be aware of the following to avoid RF interference automatically in an efficient
way.
⚫
Turn on the Antennas in the order specified as follows:
➢
When using the PoE switch, connect the Antennas to the PoE switch and turn on the PoE switch. When
connecting Antennas to a Base Station, first connect the Antennas to a Base Station.
➢
Then, turn on the Base Station.
➢
When the Base Station is powered on, the Base Station uses the radio band with the least RF interference. After that,
all Remote Antennas and Repeaters use the radio band with the least RF interference sequentially. During the search
for the radio band to be used, the power LED on the Antenna changes to red. When the search is complete, a Link LED
of the Base Station turns green. The connection status of the Antennas can be checked on the GCM. It takes 120
seconds (20 seconds per Antenna) for the six Antennas to operate normally.
Note:
After the Base Station is powered on, when Remote Antennas or Repeaters are connected and powered on, the
Antennas can be assigned radio bands that cause RF interference. In this case, the Base Station must be rebooted
one minute after the Remote Antennas or Repeaters are powered on.
⚫
Install the Remote Antennas and Repeaters from A1, A2
… A6, R1, R2… R10(RA) sequentially from the
nearest location from the Base Station.
Place Remote Antenna 1 closest to the Base Station as shown, then place the Remote Antenna 2 next to the
Base Station as shown. By following this rule, Antenna coverages A and G without RF interference can use
the same frequency channel together. This arrangement makes available radio bands efficient and fully
enjoyable. These power-on order can be determined by GCM.

Precautions for Pairing wireless Beltpacks
Pair the wireless Beltpacks to the Base Station after 200 seconds of displaying the Base Station Normal menu.
The Antennas are booted during this period. During Pairing, the radio wave of the Base Station is dramatically
down. For this reason, the Antenna can be assigned to a radio band that causes RF interference.
