For professionals The following sections covers advanced features and procedures primarily intended for professionals and advanced users. Microphone DM90 27 1. Basic setup Before setting up the product, you should decide whether it should be used as a transmitter or a receiver. You should also make sure that the menu is set to the preferred language. Change the menu language The default menu language is English. You can change language from the menu Settings. 1. Select Advanced > Settings > Language. 2. Select the language you want from the list of available languages. Wireless transmitter When used together with an ear level receiver, such as Micro Receiver DT20 or Receiver DE10, Microphone DM90 can be set to transmit the sound wirelessly by radio. The built in microphone will then act as a close range microphone that can be used as a conversation amplifier or, for example, a lecture microphone at meetings. This option is likely to provide the best sound quality as there is no risk of interference from stray magnetic fields. Configure Microphone DM90 as a transmitter If you opt for an ear level receiver, your unit should be configured as transmitter. 1. Select Advanced > SST Radio > Mode. 2. Check Transmitter. Microphone DM90 29 3. Adjust the volume by using till you find a suitable level. Neckloop receiver If the hearing aid used with Microphone DM90 is equipped with a telecoil, the microphone can act as a neckloop receiver for other Comfort Digisystem microphones. This lets you combine it with a range of microphones that provides solutions for several common problem areas. This solution is convenient if, for example, the hearing aid does not have a DAI connection. Configure Microphone DM90 as a receiver By configuring Microphone DM90 as a receiver for a Comfort Digisystem microphone, the sound will be transferred to the hearing aid through the neckloop. 1. Select Advanced > SST Radio > Mode. 2. Check Receiver. 30 Microphone DM90 2. Pairing Comfort Digisystem devices By pairing two or more Comfort Digisystem devices you ensure that they can communicate securely with each other. Comfort Digisystem is a digitally encrypted communication system that relies on unique code keys to provide transmission security. Any units that are to be used together needs to be set to the same channel and share the same code key. When you perform a pairing procedure you send information about the channel and code key from one unit to one or several others. This lets you create a channel and code key combination on one unit and distribute it to other units to form a system. The information about the channel and code key is referred to as pairing information. Microphone DM90 is able to both send and receive pairing information. Important: At delivery all units share the same factory code key. To make the system secure, you need to generate a new code key. The pairing button All Comfort Digisystem units are equipped with a pairing button. The pairing button gives you quick access to the pairing features of the device. Microphone DM90 31 Table 1: Pairing short cuts accessible through the pairing button. Option Description A single press. Takes you to the pairing menu. A long press. Sets the unit to receive pairing information. (For units with more than one channel, this affects the transmitter channel only.) A double press. Sends pairing information. (For units with more than one channel, this affects the transmitter channel only.) Change channel If a channel does not suit your setup, or if you are experiencing interference from some other radio source, you can change to a different channel via the Channel menu. 1. Select Advanced > SST Radio > Channel. 2. Choose the channel you wish to use in the channel list. Back 1 863.250 MHz 2 864.000 MHz 3 864.750 MHz The green circle next to the frequency indicates that the channel is free from interference. If the channel is occupied the circle will be grey. 32 Microphone DM90 Available channels Comfort Digisystem has a total of 38 channels to choose from. These channels should not require a license in North America. However, always verify with the local frequency assignment authority which channels are free to use and which require a licence.

Miscellaneous Microphone DM90 55 1. Radio Comfort Digisystem relies on radio technology to transfer the sound between transmitters and receivers. Like all radio systems, it communicates on specific channels. If you use two transmitters on the same channel, or neighbouring ones, there may be interference. Other electronic equipment can also interfere with radio transmissions. Channel planning To achieve optimal radio performance you need to take into account the distance between transmitters and their frequencies. A longer distance between transmitters allows you to use frequencies that are closer together. If several transmitting frequencies are being used in the same room, the frequency differences between the units should be at least 1 MHz for optimal operation. Radio range The radio range between the units is around 30 metres. However, this may vary depending on the particular environment you are in. Microphone DM90 57 2. Battery maintenance This product has a built in Lithium-Ion Polymer battery. Lithium-Ion batteries do not suffer from so called memory effects and do not need to be routinely discharged to preserve performance. The battery's capacity will degrade over time. This is normal for all rechargeable batteries. Battery lifetime is dependent on usage patterns. The battery is preferably charged little and often; it will reach 90% of its capacity after half its charging time. If stored for long periods of time, the battery is best left semi-charged. Contact your point of purchase when it is time to change the battery. Operating times vary depending on which features are used. Features such as Bluetooth can be disabled to extend operating times.
