Telex TR-800 Datasheet
TR-800 & TR-825
UHF Two-Channel Wireless Synthesized Transceiver &
Two-Channel Binaural Wireless Synthesized Transceiver
The Telex RadioCom TR-800 and TR-825 are Two-channel UHF frequency-agile wireless beltpacks for use with the BTR-800.
The TR-825 is a dual listen beltpack, allowing you to listen to “Tech” in one ear and “Production” in the other. Individual volume
controls also allow for easy level adjustment. The TR-800 and the TR-825 both have an all metal cast magnesium case, an
LCD based graphical user interface, stage announce activation, wireless talk around (ISO) activation, enhanced ClearScan,
detachable antennas and an auto-sensing headset connector that automatically switches between electret and dynamic headset
mics.
Features
On/Off & Volume Control
Turns the beltpack power on and controls head set volume.
Wireless Talk Around (WTA)
When pressed, the user’s audio is disconnected from the
wired intercom, auxiliary input/output and the base station’s
local headset. Other beltpack users, on that audio channel,
can hear the user as normal.
Stage Announce (SA)
When pressed, the user’s audio is routed to the stage
announce connector on the back of the base station. The
user also loses their sidetone as an indication that stage
announce is activated. The other wireless beltpacks and
wired users do not hear the user’s audio. The button is nonlatching and activates the nearby red LED.
Audio Channel Select Button
Allows user to select either audio channel A or B.

Bat/Overmod Light (BAT/OM)
Light will ash once when unit is turned on if the battery is
good. If the light stays on, battery is low. If the light does not
ash, battery is dead. A normal microphone gain setting will
cause the LED to ash at the beginning of most words at
normal speech levels. If the gain is too high, the LED will be
red during the complete word at normal speech levels.
Talk Light
LED is on when the talk button, SA or WTA is active.
Talk Button
Press to enable the audio path from the local headset
microphone. The “TALK” LED, #6, will turn red when
enabled. A quick press and release latches the talk function,
unless latching has been disabled. Holding the button for
over ½ a second will cause the audio path to be enabled
only for as long as the button is held. If the talk function is
latched on, pressing the talk button again will turn it off.

CONSUMER ALERT
Most users do not need a license to operate this wireless microphone system.
Nevertheless, operating this microphone system without a license is subject to
certain restrictions: the system may not cause harmful interference; it must operate
at a low power level (not in excess of 50 milliwatts); and it has no protection from
interference received from any other device. Purchasers should also be aware that
the FCC is currently evaluating use of wireless microphone systems, and these rules
are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY:
1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/
wirelessmicrophones.
