Main application samples

In trialogue setting, you are proposed to use the units with enforcing antenna to

enlarge transmitting range. In the following samples, TX means transmitter. RX

means receiver. (A), (B), (C)… … means different channels/frequencies: channel A,

channel B, channel C… …

Ａ．touring, visiting

One speaker with many listeners.

1. The speaker can transmit his voice via transmitter.

2. Other listenners can hear via attaching receivers.

The number of receivers can be added at will.

The speaker can take one EL-60 extend linker to input background music. It will make

your touring or visiting more interesting.(The speaker can also hear the music.)

- 17 -

Ｂ．Simultaneous Interpretation

1. The speaker takes one transmitter set on non-interfence channel (TX A) and one

microophone.

2. Mother language listeners take receivers set on the same channnel(RX A) as the

transmitter’s so that they can hear what the speaker is saying.

3. Interpreters take receivers(RX A) for hearing the mother language and transmit

their interpreted languages to other language listenners via attaching transmitters

(TX B, TX C … … )

4. Other language listenners can hear the interpreters’voice via the their receivers

RX B, RX C … … that are set on the same channel as that of cor responding

interpreters’.

Pay attentions:

While using multiple channels, please select channels without interence between each

other.

If one takes both one receiver for listenning and one transmitter to interprete what he

hears to another language, he needs to make the distance between the receiver and the

transmitter as far as possible to avoid being interfered.

Please try the following solution if there is still interference. Set the channel into

- 18 -

different frequency ranges, such as range A and range B.(You have to contact

SOOLAI to preset the channel frequency for you!!!)(Please refer to Frequency

diagram on page 21.)

Troubleshooting

No voice in receiver output

1. Make sure the transmitter and receiver are both powered.

2. Make sure the transmitter and the receiver are on the same channel frequency.

3. Make sure the microphone and earphone are attached appropriately.

4. Make sure the transmitter is not in Mute mode

5. Make sure the volume control on receiver is not adjusted on the minimum.

Short working distance

1. Make sure the antenna is not broken.

2. Make sure the transmitter is not close to other transmitter powers. In simultaneous

interpretation, make sure the interpreter’s transmitter and receiver are not on the

same channel frequency.

3. Try to set receiver’s SQ to “MIN -10”to check the effect.

4. Try to use another channel.

5. Check line of sight transmitting range.

Voice distortion

1. Make sure that there is no other transmitter using the same channel.

2. While using multiple channels, make sure there is no interference between each

other.

3. Make sure the transmitter’s microphone GAIN is adjusted to the best volume.

4. Try to adjust the receiver’s SQ to “MAX +10”to check the effect.

Too low voice

1. Make sure the transmitter’s microophone GAIN is adjusted at the best volume.

2. Make sure the receiver’s volume is adjusted at the best volume.

3. Replace the earphone to check the effect.

If still operating problems with your transmission installation occur, please contact

your local SOOLAI agent for assistance.
