II. For professionals
The following sections covers advanced features and procedures primarily intended for professionals and advanced users.
27Microphone DM90

Basic setup1.

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.
29Microphone DM90
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.
Microphone DM9030
Pairing Comfort Digisystem
!
2. 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 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
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.

Radio1.

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.
57Microphone DM90

Battery maintenance2.

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.
59Microphone DM90
