2.4 GHz Wireless Intercom

The Telex RadioCom BTR-24 and TR-24 series intercom is a full duplex (simultaneous talk and listen) wireless intercom system
that offers a complete stand alone solution for 2 to 10 users utilizing the full duplex feature and an unlimited number of listen-only
users. The BTR-24 system offers easy set-up, durable beltpacks, 64 bit audio encryption, easy system expansion and a 3 year
warranty. The Telex RadioCom BTR-24 system operates utilizing the license free 2.4 GHz IEEE 802.11b “WiFi” standard.

The BTR-24 system incorporates the option of three audio channels that are selectable at each TR-24 beltpack. The TR-24
beltpacks also provide the user with adjustable volume control, headset microphone level and local side tone level. The TR-24
will operate with Dynamic or Electret headset microphones and has a built-in lithium ion battery pack that will provide up to 8
hours of uninterrupted operation.

Upon start-up the BTR-24 base station automatically scans and selects the best RF (radio frequency) channel for communica­tion with a feature called ClearScan. The BTR-24 also has a built-in lithium ion battery pack that will provide up to 10 hours of
uninterrupted operation or can be operated with the included wall mount AC power supply. The BTR-24 also includes rack mount
hardware.
