Adjusting the volume of the receivers Start the transmitters to be used. Ask someone to help you adjust the volume to a comfortable level. In volume settings, adjust the volume for each receiver separately (WR1 & WR2). The speaker begins to speak into the microphone in a normal voice. The person who is listening makes the necessary volume adjustments. Test all parts of the room to check that the sound is distributed in a good way.
Menu control It is possible to make the following choices using the menu controls: Function button (moves the marker up) Menu button (opens the menu/used for selection) Function button (moves the marker down) Change language On delivery the menu language is set to English.

In most European countries, channels 1, 2 and 3 are free channels that do not require a licence. Under Increased range more channels can be selected. These channels, however, often require licences; see Radio range and channels. When the FFC box is ticked, the colour green indicates which channels have a low noise level and are suitable for use in the current environment. Check that no transmitters in the system are started when using FFC.
Receive pairing information The option Receive info makes receiver no. 1 (WR1) ready to receive pairing information from any Comfort Digisystem unit that sends info. Example: Speaker DS-10/DS-20 must reproduce the sound picked up by an existing Microphone Mini DM-05. Get Speaker DS-10/DS-20 ready to receive info as above. Then press the pairing button on DM-05 quickly twice to Send info. OK! now appears in the display on DS-10/DS-20.
Channels WR2 Setting Receiver Channel 2 (applies to Speaker DS-20 only) In most European countries, channels 1, 2 and 3 are free channels that do not require a licence. Under Increased range more channels can be selected. These channels, however, often require licences; see Radio range and channels. When the FFC box is ticked, the colour green indicates which channels have a low noise level and are suitable for use in the current environment.
Pairing Receiver WR2 Send pairing information The option Send info sends information about both the code key and the channel from Speaker DS-20 to the Comfort Digisystem units that have been activated to receive info. Example: On Microphone DM-10 select Communication – Pairing – Receive info. Then carry out Send info as in the illustration above. DM-10 shows that pairing was carried out when the text OK! appears in the display. The sound is transferred from Microphone DM-10 to Speaker DS-20.
Squelch WR2 The squelch level can be adjusted from 0-10. The higher the squelch value, the stronger the radio signal required for the receiver to work. The receivers in Speaker DS-10/DS-20 are extremely sensitive and are thus able to receive weak signals. Raise the squelch value if the receiver is open to radio channels from other transmitters that must not be intercepted. With weaker radio signals (possible interference), the receiver will be silent. The default setting for the squelch level is 2.
Lock option – Pairing buttons This option locks the pairing buttons and Pairing function via the menu. If no PIN code has been selected, the message “No PIN set or activated” will be displayed. After this you can choose a PIN code. Lock option – Menu This option locks the entire menu except the Pairing function, which can be selected using the pairing buttons. If no PIN code has been selected, the message “No PIN set or activated” will be displayed. After this you can choose a PIN code.
