Usage3.Microphone DM30 is purpose made to be used with other units ofthe same type. Together with the other units it forms a system fortwo-way communication among teacher and students.A typical set-up consists of one unit configured as ateacher unit, and one or several units configured asstudent units. This set-up allows each student to hearthe teacher and fellow students that are using thepush-to-talk feature.Figure 1: The teacher's voice is mixed with the voice ofthe student pushing the function button and sent backout to the rest of the class.19Microphone DM30
Alternatively, two units can be used together to allowteam-teaching. A secondary unit, worn by the assistantteacher, then transmits sound via the primary teacher'sunit to the student's units.Figure 2: The teacher's voice is mixed with the voice ofthe assistant teacher and sent back out to the class.Use the device as a teacher unitUse Microphone DM30 as a teacher unit to transfer the voice ofthe teacher, mixed with the sound from another unit in the system,directly to the students.Use a unit configured as a Master Unit. Verify that the -symbolis visible in the display. For information on configuring the devicesee Basic setup on page 27.Microphone DM3020
1.Have the teacher attach the unit to his or her clothes with theclip, or use a necklace to hang it around the neck.For optimum sound quality the unit should be placed no morethan 30 cm (12 in.) from the mouth.2.Let the teacher talk into the microphone in a normal voice andmake sure the students can hear.3.If the teacher is using head phones or a neckloop formonitoring, he or she can use to adjust the volume to asuitable level.Use the device as a student unitStudents can use the device to listen and talk to other personswearing Microphone DM30 devices.Use a unit configured as a Companion Unit. Verify that -symbolis visible in the display. For information on configuring the devicesee Basic setup on page 27.21Microphone DM30

For professionalsII.The following sections covers advanced features and proceduresprimarily intended for professionals and advanced users.25Microphone DM30
Basic setup4.Before setting up the product you should make sure that the menuis set to the preferred language. You should also decide whetherit should be used as a Master Unit or as a Companion Unit.Change the menu languageThe default menu language is English. You can change languagefrom the menu Settings.1.Select Settings > Language.2.Select the language you want from the list of availablelanguages.Master UnitThe Master Unit is the device in a system that acts as a mixer forother paired Microphone DM30 units. It receives sound fromanother unit and mixes it with the sound from the built-inmicrophone. The mixed audio is transmitted on a separate masterchannel to any paired receivers. Listeners will hear both the MasterUnit and the second unit on that channel. This lets two personstalk freely without forced interruptions.By using push-to-talk microphones, the Master Unit can be usedwith multiple microphones. Such a set-up is useful in classroomsituations were the students take part in discussions and need tohear the classmates and the teacher.27Microphone DM30
Configure the device as a master unitYou typically configure the device as a Master Unit when it is goingto be used by a teacher or lecturer. With this set-up the device willmix the voices of the teacher and student and broadcast them tothe class.1.Select Mode.2.Check Master Unit.When the unit is programmed as Master Unit, the display shows.Companion UnitA Companion Unit will let the user listen to the master channeland communicate with other Companion Units by relaying soundthrough the Master Unit.A Companion Unit is typically used with the push-to-talk featureenabled to let several users take turn transmitting sound to theMaster Unit.Configure the device as a Companion UnitThe Companion Unit setting is normally used if the device is usedby a student. It lets the student hear both the teacher and fellowstudents.1.Select Mode.2.Check Companion Unit.When the unit is programmed as Companion Unit, the displayshows Microphone DM3028
Configure the function buttonThe function button on the unit can be configured for differentpurposes through the menu option Mode. For example, it can beset to push-to-talk, to allow the use of several microphones on asingle channel, or as a mute switch to temporarily mute the soundwhen having a private conversation.1.Select Mode > Button Mode.2.Select one of the following options:DescriptionOptionThe button has no function.NoneThe microphone is on while the button ispushed and muted on release.Push to talkThe microphone is toggled on and off witheach press off the button.Mic.

(MasterUnits only.)Receiv. On/Off29Microphone DM30
Pairing Comfort Digisystemdevices5.By pairing two or more Comfort Digisystem devices you ensurethat they can communicate securely with each other.Comfort Digisystem is a digitally encrypted communication systemthat relies on unique code keys to provide transmission security.Any units that are to be used together needs to be set to the samechannel and share the same code key.When you perform a pairing procedure you send information aboutthe channel and code key from one unit to one or several others.This lets you create a channel and code key combination on oneunit and distribute it to other units to form a system.The information about the channel and code key is referred to aspairing information. Microphone DM30 is able to both send andreceive pairing information.!Important: At delivery all units share the same factory code key.To make the system secure, you need to generate a new codekey.The pairing buttonAll Comfort Digisystem units are equipped with a pairing button.The pairing button gives you quick access to the pairing featuresof the device.31Microphone DM30

Radio11.Comfort Digisystem relies on radio technology to transfer thesound between transmitters and receivers. Like all radio systems,it communicates on specific channels. If you use two transmitterson the same channel, or neighbouring ones, there may beinterference. Other electronic equipment can also interfere withradio transmissions.Channel planningTo achieve optimal radio performance you need to take into accountthe distance between transmitters and their frequencies. A longerdistance between transmitters allows you to use frequencies thatare closer together.If several transmitting frequencies are being used in the sameroom, the frequency differences between the units should be atleast 1 MHz for optimal operation.Radio rangeThe radio range between the units is around 30 m (100 ft). However,this may vary depending on the particular environment you are in.59Microphone DM30
Battery maintenance12.This product has a built in Lithium-Ion Polymer battery. Lithium-Ionbatteries do not suffer from so called memory effects and do notneed to be routinely discharged to preserve performance.The battery's capacity will degrade over time. This is normal forall rechargeable batteries. Battery lifetime is dependent on usagepatterns. The battery is preferably charged little and often; it willreach 90% of its capacity after half its charging time. If stored forlong periods of time, the battery is best left semi-charged. Contactyour point of purchase when it is time to change the battery.Operating times vary depending on which features are used.61Microphone DM30
Troubleshooting13.Consult the following guide if you have problems with yourequipment. If you still have questions, please contact your pointof purchase.SolutionCauseSymptom•Charge the battery.•Press for at least 2sec.•The battery is depleted.• is released too soon.•The device does notstart.•Reduce the distance tothe speaker.•The distance betweenthe microphone and theperson speaking is toolong.•Poor speechintelligibility.•Reduce the distance tothe receiver.
