GREEN = Battery is charged. 3. AP Active Light – the green light will blink to indicate that the BTR-24 has successfully booted and is operating. 9. Programming Input – RJ-45 jack for wired Ethernet connections. 4. RF Channel Display – displays the current RF channel of operation.
7 full hours to completely The supplied antennas are vertically polarized. This means that charge a dead battery. A BTR-24 can also be used while charging both the transmitting and receiving antennas should operate in the the battery, but this will require a much longer time to completely vertical position for the best performance.
BTR-24 Base Station The supplied omni-directional antennas have a circular antenna NOTE: Antennas should never be mounted on, or next to metal, pattern and radiate RF signals equally in all directions. When such as beams, walls with metal studs, equipment using the omni-directional antennas, the base station should be racks, etc.
NOTE: The antennas listed in the “Accessories and Replacement Parts” section of this manual have been approved and authorized for use with the BTR-24 base station. Using an unauthorized antenna may be illegal. Figure 3-3 Beltpack on Hip...

Many channels, overlapping and non-overlapping, can co-exist Coverage without noticeable interference if channel utilization, or amount Area of channel activity, is minimal. For example, a BTR-24 with ten (10) wireless full-duplex TR-240s is operating at maximum Area channel utilization. A second BTR-24 operating on an adjacent...
/ switches are set to pass packets for the intercom system devices. When BTR-24 base stations are operating indoors and through walls, the interference will be greatly reduced and the separation distances required to keep them from interfering will also be reduced.

ClearScan and select the optimal RF channel for operation each time it is booted. When Auto-ClearScan is disabled, the BTR-24 will operate on the last RF channel set by the user. By default, Auto-ClearScan is disabled.
To place a BTR-24 into long term storage: After the last event: a. If the BTR-24 was used for 4 hours or less then do not recharge the battery pack. b. If the BTR-24 was used for more than 4 hours then recharge the pack for two hours (via direct charge).
(Channels 1, 6, and operate on any RF channel between 1 and 11. In Europe and China, the BTR-24 system has the ability to operate on any RF 11). In Europe and China, there are more non-overlapping channel between 1 and 13.
Figure 8-2 files. 802.11 Transmitter Spectral Mask at 2.4GHz For a real-time audio application, like the BTR-24 system, Figure 8-3 shows that the “non-overlapping” RF channels devices cannot simply wait for extended periods of time for the actually do overlap at lower signal levels. The reality is that even channel to become clear.
In some environments, RF interference can be controlled, and in others, it cannot. There are numerous ways that a BTR-24 system • If users are co-located in multiple areas and/or separated operator can avoid a significant impact to RF interference.
Wired / Network Interference The BTR-24 system allows both wireless and wired users to operate at the same time. Similar to wireless interference, wired users may experience performance degradation if operating over an existing Ethernet infrastructure that has a lot of traffic.
Section 9 - Hardware Specifications Program The Program connector is a standard 8-pin modular jack (RJ-45). This port is to be used with standard Ethernet cables of Category 5e or better. The program connector has automatic crossover detection so both straight and crossover cables can be used. Refer to Figure 9-1 for the wiring diagram of the program port.
