Use only attachments/accessories specied by the manufacturer.
Unplug the unit during lightning storms or when unused for long periods of time.
Be advised that dierent operating voltages require the use of dierent types of line cord and attachment plugs. Check the voltage in
your area and use the correct type.
Use only the power supply provided by Williams Sound. Other power supplies may have similar specications, but may not be
equivalent in emissions ratings, in-rush current, etc. Use of an unapproved power supply may leave the device partially or completely
inoperable, and will void the warranty.
This apparatus has been designed with class-1 construction and must be connected to a main socket outlet with a protective ground

This apparatus must be grounded.
The MAINS plug or an appliance coupler is used as the disconnect device, so the disconnect device should remain readily operable.
System Overview
Thank you for purchasing the T2800, 863 MHz FM Base Station Transmitter. This transmitter was designed for Europe and other areas
where 863 MHz is the permitted frequency range for hearing assistance. This transmitter is compatible with Williams Sound R2863
Receivers.
Much like a miniature radio station, the T2800 broadcasts a speaker’s voice, pre-recorded audio program or live audio over a channel
in the 863 MHz FM frequency band. This hearing assistance system helps large or small groups overcome background noise, and
distance, to clearly hear the speaker or audio program.
The T2800 features Mic Inputs, Line Inputs, and a built-in MP3 player for pre-recorded content. A dual-color tft display shows settings
for transmit channel, transmitter locked, volume, record volume, mode, cycle (repeat), total number of audio les and current audio le
playing.

Operating Instructions
The transmitter can broadcast programs from (1) a live mic, (2) line level input, (3) MP3 audio les from an SD Card or USB
Flash Drive, (4) Record from the MIC inputs and play back the recording.
LIVE MICROPHONE
1. Make sure the unit is turned OFF.
2. Connect a microphone with a 3.5 mm plug into one of the 3.5 mm jacks on the rear of the T2800. Note: these two jacks are
mixed internally, so two speakers can use individual microphones at the same time and both will be heard by the audience.
3. Turn the unit on.

5
Williams Sound | T2800 863 MHz Transmitter - Europe | User Manual
4. Change the input to Microphone:
a. Push and hold the Lock button until the lock symbol turns o.
b. Push the mode button repeatedly until “MODE” on the display begins blinking.
c. Use the Left, right buttons (<,>) to change the Mode to “MIC”.
d. Push-and-hold the LOCK button until the lock symbol turns on.
5. With a R2863 receiver, tune to the channel displayed on the front of the T2800. For example, “TX: 01”.
6. Have one person listen to the receiver while someone speaks into the microphone. Determine if the level is too high or too low*.
7. If the transmitter level needs to be adjusted, push-and-hold the LOCK button to turn it o. Then repeatedly push the MODE button
until “VOL:” is ashing on the display. Use the left, right (<,>) buttons to adjust the volume of the transmitter to an acceptable level.
*Note: If during steps 6 or 7, the audio level meter pulses and stays mostly in the red, the transmitter volume may need to be lowered.
The idea is to have the peaks of a persons voice (like the “p” sound) take the meter into the red, but while speaking most of the audio
should be in the blue range of the meter. Another way to know if the level is too high, is if the speaker’s voice sounds distorted or not
clear when they are speaking at the proper (recommended) distance from the microphone. Adjust the audio so that the speaker’s
voice is loud and clear without distortion.
LINE LEVEL AUDIO PROGRAM
1. Make sure the unit is turned OFF.
2. Connect the line-level source to the RCA jacks on the rear of the T2800. Note: these two jacks are mixed internally, so the L,R
audio is combined into one mono channel that will be heard by the audience.
3. Turn the unit on.
4. Change the input to the RCA Line Level jacks:
a. Push and hold the Lock button until the lock symbol turns o.
b. Push the mode button repeatedly until “MODE” on the display begins blinking.
c. Use the Left, right buttons (<,>) to change the Mode to “LINE”.
d. Push-and-hold the LOCK button until the lock symbol turns on.
5. With a R2863 receiver, tune to the channel displayed on the front of the T2800. For example, “TX: 01”.
6. Have one person listen to the receiver and start the audio program playing on the source device. Determine if the level is too high
or too low*.
7. If the transmitter level needs to be adjusted, hold the LOCK button to turn it o. Then repeatedly push the MODE button until
“VOL:” is ashing on the display. Use the left, right (<,>) buttons to adjust the volume of the transmitter to an acceptable level.
*Note: If during steps 6 or 7, the audio level meter pulses and stays mostly in the red, the transmitter volume may need to be lowered.
The idea is to have the peaks of the audio program take the meter into the red, but most of the audio should be in the blue range of
the meter. Another way to know if the level is too high, is if the audio program sounds distorted or not clear. Adjust the audio so that
the audio program is loud and clear without distortion. Always adjust the audio on the source device rst, and adjust the transmitter
audio “VOL” output second.
MP3 PLAYER
1. Make sure the unit is turned OFF.
2. Insert a Micro SD card, or a USB Flash Drive, into the appropriate slot shown in “Rear View”.
3. Turn the unit on.
4. Change the input to the MP3 Player:
a. Push and hold the Lock button until the lock symbol turns o.
b. Push the mode button repeatedly until “MODE” on the display begins blinking.
c. Use the Left, right buttons (<,>) to change the Mode to “MP3”.

6
Williams Sound | T2800 863 MHz Transmitter - Europe | User Manual
d. Push-and-hold the LOCK button until the lock symbol turns on.
5. Push the Play button on the T2800 to begin the MP3 player playing. The audio meter on the right should begin pulsing with the
audio.
6. Using the Mode button, set the “Cycle”
a. All Cycle: continuously plays all MP3 les going from 001 to the the last le, then starts at 001 again.
b. Single Play: Plays the current (CurreNum) MP3 le once, then stops.
c. Single Cyc: Plays all of the MP3 les from 001 to the last le, then stops.
7. With a R2863 receiver, tune to the channel displayed on the front of the T2800. For example, “TX: 01”.
8. Have one person listen to the receiver. Determine if the level is too high or too low*.
9. If the transmitter level needs to be adjusted, push-and-hold the LOCK button to turn it o. Then repeatedly push the MODE button
until “VOL:” is ashing on the display. Use the left, right (<,>) buttons to adjust the volume of the transmitter to an acceptable level.

Troubleshooting
No Sound:
a. Check that the power supply is plugged into the AC outlet, the power switch is on, and the front display is on.
b. Check the Mode on the front display to make sure the intended input is selected.
c. If using the Line Level inputs, make sure the device plugged into these jacks is playing.
d. With any source being used, the audio level display meter should be pulsing with the audio. If it is not, the transmitter will not
be broadcasting anything.
e. Make sure the receiver is tuned to the same channel as shown on the front of the transmitter.
f. Make sure the volume on the receiver is high enough to hear the audio.
g. When playing MP3 les, make sure the “Cycle” is set to repeat correctly; i.e. if it plays one le and stops, it is probably set to
“Single Play”.
