SECTION 1: INTRODUCTION
LAON Technology („LAON‟) is a leading-edge technology developer and innovative solutions provider in Digital Wireless Audio
Communications and Wireless Intercom Systems.
LOAN‟s digital wireless Intercom System, LT250 operates in license-free 5GHz UNII band securing high performance wireless
coverage and scalability. And LAON‟s technologies such as non-compressed audio transmissions, triple diversity (3D), noise
cancelling and automatic interference avoidance realized to enable our high standard intercom users to experience break-up free
audio communications. LT250 provides a full flexibility on grouping allowing up to three (3) communication group channels to be
allocated with up to nine (9) full-duplex audio paths –eight (8) channels for Belt Pack and 1 (one) channel for Base Station. It also
maintains the audio clarity high in quality even in noisy environments and guarantees private and secured communications by AES
256bit Level-3 encryption. More details to be followed;
Up to 32 Belt Packs can be paired up with each Base Station in the normal mode and additional 96 Belt Packs can be paired up
under the shared mode. Those Belt Packs under the shared mode operate only in „Push-to-Talk‟mode. 32 Belt Packs with which
have been paired up with Base Station in the normal mode can be monitored, and additional 96 Belt Packs with which have been
paired up in the shared mode cannot be monitored at the Base Station.
Up to three (3) communication groups, single or multiple, can be allocated and configured flexibly to the Base Station, Belt Pack
and Auxiliary input/output. The communication group allocation to Belt Packs, Auxiliary input/output and the Base Station itself can
be set each by the Base Station operator using the Base Station menus.
As shown from the figure, „Communication group allocation‟ of the System Usage Example below, for instance, you may allocate
only one group to Belt Pack # 1 (Group # 1 for BP1), two groups to Belt Pack # 3 (Group # 1 & 2 for BP3) and all the three (3)
groups to Base Station (Group # 1, 2 & 3 for Base Station).
Belt Packs and other devices in the same communication group can talk with others in the designated group. The selected
communication group is displayed on the NORMAL menu of the Belt Pack as “1” through “3”.
Base Station and Auxiliary devices can communicate at the same time with all the groups allocated up to three (3). The selected
communication group is displayed on the NORMAL menu of the Base Station as “1” through “3” and “A”.
Remote Base Station (RBS) can be connected to the Base Station through LAN, composing customized and continuous coverage,
and enabling automatic roaming between coverage zones. The Remote Base Station supports the communications with Belt Packs
in remote area from the Base Station and shares up to nine (9) full duplex audio paths with the Base Station within the coverage
area. Standard CAT-5 cable is used to connect the Remote Base Station either directly to the LAN port on the rear panel of the
Base Station, or via network switch. Remote Base Station can be powered by local electricity or network switching devices which
has the Power-over-Ethernet (POE) function. Due to network traffic delay, audio breakups might occur in communications between
Belt Packs in the Remote Base Station coverage, or in communications with Belt Packs which are connected to the Base Station. In
that case, it is recommended to compose the network exclusively.
OLED displays on the front panel of the Base Station and Belt Pack are for setting up operations and monitoring. The Base Station
can monitor connectivity status among the Base Station, Remote Base Station and Belt Packs. Moreover, the Base Station can
monitor each Belt Pack‟s Received Signal Strength Indication (RSSI) level, battery level and microphone gain.
The USB port on the rear panel of the Base Station is supposed to be used for communication with PC to exchange data and
update programs.
5

Audio latency is one of the most critical factors in all digital wireless system. LT250 realized low latency, less than 23msec for total
one-way system latency from the Belt Pack to the Base Station.
Up to five Belt Packs and two Belt Pack Batteries can be charged at the same time by Battery Charger (BATCHG125). You can use
rechargeable Battery Pack (BAT50) or two AA 1.5V alkaline batteries in the Belt Pack.
LT250 Digital Wireless Intercom System powered by LAON‟s leading edge technology provides not only high quality audio
performance but reliable coverage, diverse functions and flexibilities.

BS250 BASE STATION SETUP
Following descriptions are stand-alone LT250 system configuration. Using additional devices such as Remote Base Station,
auxiliary input/outputs and 8ohm speaker will be explained later.
Step 1: Put two enclosed antennas to the antenna connectors (#1 and #5) on the rear panel of the Base Station. Turn the sleeve on
each of the antenna connectors clockwise to tighten them, and ensure that the antennas are connected firmly.
NOTE 1: These two antennas must be positioned vertically and be folded completely as 90 degree. Otherwise, it will be
caused to weaken the signal.
NOTE 2: While attaching the antennas directly to the rear panel of the Base Station, the Base Station should be away
from any metal obstructions, walls, and electronic equipments that can create radio interference. It is highly
recommended to place the antenna as high as possible in the center of the coverage and away from
obstructions. The antenna extension cable enables an antenna to be mounted away from the Base Station to
extend coverage.
Step 2: Plug the DC cable from the enclosed wall-adapter power supply into the 12VDC POWER connector (#9) on the rear of the
Base Station. Plug the large female connector at the end of the AC power cord into the power supply.Plug the other end of
the AC power cord into a standard wall outlet.

BP250 BELT PACK SETUP AND PAIRING UP
When you operate each Belt Pack for the first time with the Base Station, you must pair up the Belt Pack with a Base Station. This
pairing process allows a Base Station and a Belt Pack to recognize each other. The Base Station will identify all Belt Packs that
paired up before and will recognize the difference between the Belt Packs. If a Belt Pack is added or replaced later, the new one is
necessarily to be paired up with the Base Station. If the previous Belt Pack will not be in use, turn off the Belt Pack or do the paring
process again with a different label.
A maximum of 32 Belt Packs can be paired up with each Base Station in the normal mode. If you need to pair up more than 32 Belt
Packs with the Base Station, additional 96 Belt Packs can be paired and those additional Belt Packs can be used in shared mode.
Belt Packs with which have been paired up in the shared mode operate in the „Push-to-Talk‟mode and are allocated to
Communication Group “3” automatically. Base Station monitors the status for 32 Belt Packs in the normal mode and does not
monitor for additional 96 Belt Packs in shared mode.
NOTE: BP250 can also be paired up with the Base Station, MS150 and can connect with either Base Station that is lastly paired up.
BELT PACK SETUP
Before pairing up the Belt Pack with the Base Station, set up all Belt Packs as following steps:
Slide the cover down to open the battery cover (#10), and put a fully charged rechargeable battery pack (BAT50) or battery sled
with two fresh AA 1.5V alkaline batteries. Make sure the position of polarity (+, -) is correct. Close the battery cover.
