General Description
The RTS BTR-24 base station is a digital, multi-channel, wireless
access point offering reliable and secure, full-duplex
communication with up to 10 wireless TR-240 (or TR-24)
beltpacks and almost an unlimited number of half-duplex
beltpacks.
Operating in the 2.4 GHz frequency band, the BTR-24 uses the
widely adopted IEEE 802.11 technology and is approved for
license free use in most countries. The system also incorporates
ClearScan intelligence which will automatically select the optimal
radio frequency (RF) channel for communication.
The RTS BTR-24 has the ability to configure multi-level 802.11
wireless security features, such as packet encryption and MAC
address filtering, to provide a highly secure wireless intercom
system.
The BTR-24 base station serves as a central relay location which
handles the audio traffic between TR-240 (or TR-24) beltpacks.
The BTR-24 is perfectly suited for stand-alone operation and can
also interface with other BTR-24 and BTR-240 base stations to
extend range and provide wireless communication coverage to
multiple locations.
The BTR-24 base station has an internal rechargeable Li-Ion
battery that will provide up to 10 hours of uninterrupted
operation.
System Features
•Uses the widely adopted 2.4GHz IEEE 802.11 WLAN
technology.
•No FCC license required and no license required in most
countries world-wide.
•Multi-level wireless security and audio encryption.
•ClearScan intelligence to automatically select the best RF
channel to operate.
•Up to 10 wireless full-duplex TR-240 (or TR-24) beltpacks
per base station and nearly an unlimited number of half-duplex
beltpacks.
•Multiple options for antenna connections and accessories.
•BTR-240 base stations and BTR-24 access points can be
linked together to provide a wider wireless coverage area.
•Dependable, rechargeable, wide temperature range, Li-Ion
battery with low battery indicator.
•BTR-24 can be powered from external AC for endless
operation in permanent installations.
Important Safety Instructions
Prior to operation, read and follow all safety instructions.
Throughout this manual, the following notations are used:
WARNING: Indicates a situation which, when not avoided,
has the potential to result in death or severe
injury.
CAUTION: Indicates a situation which, when not avoided,
has the potential to cause the system to no longer
function properly or cause equipment damage.
NOTE: Indicates important additional information.
WARNING:
To reduce the risk of fire or electrical shock, adhere to the
following instructions:
•Do not expose the system components to rain or
moisture.
•Ensure that the power cords are in a safe and secure
place that is protected from being walked on or
pinched.
•Do not remove the cover or product casing. All
technical service must be performed by qualified
service personnel.
WARNING:
Excessive sound pressure from headsets can cause hearing
loss! The duration of exposure to high volumes must be
shortened to reduce the chance of hearing damage. Signs of
prolonged exposure to excessive audio levels include:
•Ringing sounds heard in ears.
•Can no longer hear high frequency tones, if only for a
short time.

1. On/Off Switch – turns the power on/off.
2. Power / Low Battery Light – indicates the base station
has power, either from the internal battery or AC power
connected to the unit.
GREEN = Battery OK
RED =Battery Low (approx. 30 minutes left)
NO Light =Battery Depleted (needs charge)
3. AP Active Light – the green light will blink to indicate
that the BTR-24 has successfully booted and is operating.
4. RF Channel Display – displays the current RF channel of
operation.
5. <SELECT> Button – quickly press and release to
increment the RF channel of operation.
6. Receive Antenna Jack – reverse "TNC" connector.
7. Charge / Power Jack – used to charge the internal Li-Ion
battery and power the unit directly from a wall outlet.
Accepts a 12VDC regulated power supply with at least a
1.5 A current capacity.
8. Charge Light.
RED =Battery is charging.
GREEN = Battery is charged.
