Important information

The system components correspond to all relevant directives of the EU and are therefore marked with

The components are suitable for indoor use so may require protection if used outdoors against water, high air humidity and heat (admissible ambient temperature: 0°C – +40 °C).

For cleaning only use a dry, soft cloth; never use water or chemicals.

No guarantee claims for the units and no liability for any resulting personal damage or material damage will be accepted if the units are used for other purposes than originally intended, if they are not correctly connected or operated, or if they are not repaired in an expert way.

The TT 40-R receivers are capable of producing sound pressure exceeding 85 dB(A). 85 dB(A) is the sound pressure corresponding to the maximum permissible volume which is by law (in some countries) allowed to affect your hearing for the duration of a working day. Higher volumes or longer durations can damage your hearing. At higher volumes the duration must be shortened in order to prevent hearing damage.

If a TT 40-T transmitter or TT 40-R receiver unit is not in use for long periods of time then remove the battery to avoid leakage.

Under no circumstances should non-rechargeable batteries be used with the TT 40-C charger.

Always check the TT 40-C charger and power supply unit (PSU) with mains lead for visible damage before use. Do not operate if any damage is found.

What is a tour guide system?

A tour guide system is a wireless audio system used to transmit a message from a presenter to listeners. The presenter simply speaks into a microphone connected to a transmitter and the listeners use receivers with earphones to hear the message.

Tour guide systems are ideal for-

Guided Tours

Indoors and Outdoors

Bus and Equestrian and other

City Tours Environments Sports Training

Museum and Heritage

Site Tours



Hearing Simultaneous

Support Interpretation


System overview

Tourtalk is a portable wireless tour guide system that helps tour groups overcome background noise and distance from the guide. Tourtalk is easy to set up and use, operates up to a distance of 120 metres and accommodates a limitless number of receivers. This one way radio communication system enables the guide to speak at a comfortable level to the group whilst ensuring they are clearly heard. Up to 12 tour groups can operate simultaneously within the same environment without cross interference*.

The guide uses a transmitter. They can either speak into a microphone or connect another audio device e.g. mp3 player, to communicate with the group. The audio message is then transmitted on a specific channel (frequency) in the form of radio waves to the receivers.

The audience members use a receiver to convert this radio signal back to audio. Each person is supplied with a receiver set to the same channel (frequency) as the presenter. The user simply connects an earphone to hear the message and adjusts their volume to a comfortable level.

Both the transmitter and receivers are supplied with a lanyard and clothing clip to enable hand-free use. Each unit operates on a single AA battery. Either Alkaline or Ni-Mh rechargeable batteries can be used. A charger/transport case provides protection and secure storage for the units between tours.

The Tourtalk tour guide system has been designed to be very user friendly and can be set-up within minutes. As the system is completely wireless it can be operated indoors or outdoors and requires no installation.

A wide range of accessories are available for the system to suit each application (see page 13). Whether the tour is taking place in a cathedral or a noisy workshop, a Tourtalk system can be used to provide a professional experience for your guests.

System setup

TT 40-R Receiver TT 40-T Transmitter

Firstly, switch a receiver on by pressing the power button until ON is displayed on the screen.

Press the Up/Down buttons to to select a free channel. A free channel can be identified by the signal indicator not illuminating. If the signal indicator illuminates blue then the receiver is picking up either another transmitter or interference on the selected channel.

Please note. If no button is pressed for 5 seconds the buttons will be locked automatically and the lock icon will appear on the screen. To unlock the unit press and hold the up/down buttons until the lock icon disappears.

If multiple tours or multiple languages are to be transmitted within the same environment then each transmitter must be set to a different channel. Up to 12 of the 40 channels can be used simultaneously (depending on local conditions).

The channels can be identified on the table on page 12.

Two channel groups are programmed into each unit. Group 1 G1 has all 40 channels selectable and Group 2 G2 only has the 12 channels that can be used simultaneously.

Factory default is set to Group 1 G1. To change group, switch the unit off by pressing the power button until OF is displayed on the screen.

Press the power and down button together until the screen displays G1 with the 1 flashing. Change the group by pressing the down button. Once the group is selected press the power button and the unit will switch to the new group.

To change channels in the new group follow the previous instructions.

Once all the receivers have been programmed to the correct channel the transmitter can be switched on by pressing the power button. ON will be displayed on the screen and the signal indicator will illuminate blue. The transmitter channel must now be programmed to the receivers channel by following the previous instructions.

The signal indicators will illuminate on each receiver once they receive a signal from the transmitter.

If the receiver signal indicator fails to illuminate blue make sure the unit is within range of the transmitter.

A Hi-Lo switch is located within the battery compartment. This can be used for-


Hi - Increase transmission range but reduce battery life.

Lo - Reduce transmission range and increase battery life.

Receiver (Squelch)

Hi - Increase reception range.

Lo - Reduce reception range.

Please Note. Hi is up and Lo is down.

Once the transmitter and receivers are set to the correct channels the system is ready to be used.

Getting started

The guide should switch the transmitter on and plug-in the lapel microphone (or most suitable microphone if any accessories have been purchased).

The guide can then distribute the receivers to the group.

As each receiver is issued to a member of the group the guide should switch on the receiver, supply an earphone, and explain where the volume control is located.

Tip. The guide can play music via an mp3 player plugged into the Aux in socket on the transmitter (with the mic muted) while issuing receivers before the tour. This gives the group confidence the system is working as well as providing something for the group to listen to as the guide is getting ready.

Before the tour starts the guide should briefly carry out a speech test ensuring each group member can hear clearly.

After the tour

When the tour has finished the guide should retrieve all the receivers. The transmitter and receivers should then be switched off to preserve battery life for the next tour. The battery status is displayed on the screen.

Each unit operates on a single AA battery. Either Alkaline or Ni-Mh rechargeable batteries can be used.

If Alkaline batteries are used and need replacing, remove the rear cover by sliding it down to access the battery compartment. The old battery should be removed and disposed of at special collection points. A new battery can then be inserted. Always check the polarity is correct.

If Ni-Mh batteries are being used then these can be recharged without removing them from each unit. A dedicated charger/transport case can recharge up to 25 transmitters/receivers as well as providing protection and secure storage.

Using the charger

Place the case on a flat surface near a mains outlet.

Open the lid, and if necessary remove it by taking it off the hinges by sliding the lid to the left.

The charger unit can either be used within the case or removed by lifting it out using the two handles.

Remove the PSU and mains lead from the storage compartment.

Connect the DC plug of the PSU into the DC socket on the left of the charger. The DC plug must be inserted with the symbols facing up.

Please note. If the charger is being used within the case, then the protective cap on the side of the case will need to be removed to gain access to the DC socket

Connect the mains lead between the PSU and a mains outlet.

Always make sure the case lid is open or removed to ensure there is sufficient ventilation.

Switch the mains socket on and the power on indicator will illuminate.

When the charger is switched on the charger status indicators will briefly flash – Green-Red-Red.

Please note. If no charging slots are occupied for one hour, the charger will switch to power saving mode, and the power on indicator will flash slowly. Once a transmitter/receiver is inserted into a charging dock normal charging mode will resume.

Insert the transmitters/receivers into the charging docks. Each unit can only be inserted in one way.

The corresponding charging status indicator will illuminate as each unit is inserted. The status can be read as-

Red-The battery is being recharged

Green-The battery is fully charged

Flashing-Charging error. e.g. wrong or faulty battery, battery inserted the wrong way round.

Trouble shooting

The transmitter or receiver won’t switch on.

Check the battery is in good condition and has charge.

Check the battery is fitted correctly.

The transmitter is on but nothing can be heard on the receiver.

Check the volume control is turned up on the receiver.

Check the mute button isn’t depressed on the transmitter.

Check the receiver is set to the same channel as the transmitter and within range.

Check the microphone on the transmitter and earphone on the receiver are in good working order.

The transmitter and receiver are on the same channel but interference can be heard.

Switch the transmitter off and see if the signal indicator is illuminated on the receiver.

If it is, make sure no other transmitters are operating on the same channel.

If there are no other transmitters operating on the channel then the receiver may be receiving external interference.

Change channels on the receiver until the signal indicator doesn't illuminate and then set the transmitter to this new channel.

If no channels are available then try switching the transmitting range to high on the transmitter and the receiving range switch to low on the receiver.

An mp3 player is connected to the Aux-in on the transmitter and the sound is too quiet on the receiver.

Check the volume on the mp3 is turned up. Adjust the volume of the mp3 player whilst listening with a receiver so it matches the same volume as the microphone.

Check the volume is turned up on the receiver.

A person who wears a hearing aid is using the optional neck loop with a receiver but can’t hear anything.

Check with the person that their hearing aid has a ‘T’ telecoil program. If they do, ask them to set their hearing aid to this program, check the volume on the receiver is set to maximum and the neck loop is worn around their neck like a necklace.

Check the receiver is working correctly by connecting an earphone.
