Telex Model XO-1 Beltpack

General Description:

The Telex model XO-1 beltpack transceiver
is intended for use as a belt worn wireless
full duplex intercom radio. Multiple XO-1
beltpacks can be used with a XO-AP access
point to communicate with each other over­the-air.

The XO-1 uses 802.11 technology to receive
/ transmit within one channel of the 1 – 11
(2.412 to 2.462 GHz) channels of the 2.4
GHz ISM band. Its operation is license free.

The transmit and receive antenna are
internal to the beltpack so the unit has a
smaller profile and the antennas are
protected from possible damage.

The XO-1 is powered via an internal Li-Ion
battery that will provide up to 8 hours of run
time at room temperature.

The top panel provides on/off/volume
control, channel select buttons and lights,
talk button and battery status light.
