The Telex TR-240 2.4 GHz Wireless Intercom Beltpack (A4M / Telex) offers high-quality communication and versatile options. The durable ABS beltpack works in conjunction with a BTR-240 base station to provide clear wireless communication using license-free 2.4 GHz IEEE 802.11b WLAN technology. Up to 8 beltpacks can work together in full-duplex mode, while a virtually unlimited number of half-duplex beltpacks can also be added. You can expand your coverage range by adding BTR-24 access points to your system, and the beltpack itself can also act as an access point.
The TR-240 has multi-level security and audio encryption to ensure that your conversations stay private. ClearScan channel selection will automatically choose the best available wireless channel. The beltpack also has a 2-/4-wire intercom interface to support wired operation. The A4M / Telex headset connector can automatically detect whether your headset has an electret or dynamic microphone, and will adjust accordingly.
The beltpack has easy-to-use color-coded controls for convenient operation. The TR-240 uses a removable rechargeable Li-ion battery that provides up to 8 hours of operation per charge.
