5Microphone DM105) Getting startedChargingThe Microphone DM10 is chargeable. Charge the DM10 at least 2 hours before using it the first time. An empty battery is fully charged within 2 hours. During charging, the function indicator shows red and a lightning bolt appears through the battery symbol in the display. Once the battery symbol is filled with green columns and the functions indicator shows green the unit is fully charged and switches to automatic float charging. Connecting a charger to the Microphone DM10Please note: Only use the charger supplied by Comfort Audio.Changing the battery without the assistance of an authorized dealer will void the Limited Warranty.First time useSwitch on the transmitter by pressing the On/Off button for around two seconds.Connect clip-on-microphone or any other microphone if desired.DM10 can be attached with its clip to your clothes or carried around the neck with the delivered neck loop (2 lengths available). The Microphone DM10 is a microphone for closer range. It works best if worn approx. 12 inches (30 cm) from the mouth.WARNING! The necklace should not be used if there is a risk of getting stuck, e.g. in a machine or other objects.6) Menu and settingsMenu controlThree different selections can be made:To access the menu, press the menu control:BackCommunication Channel PairFunction Silence button Push to talk Push/Cont FCR FCR indicatorSettings PIN-code Charge Language Name Inputs Func. indicator Factory ResetKey lockAboutScroll upPress/selectScroll downBack (relates to both the main menu and submenus)Here you can choose to return to the menu and to the main display. CommunicationChannelTo use the receiver and the transmitter together, they must be set to the same channel. The transmitter and receiver are set to the default channel by the manufac-turer.This does not apply to units with both sender and receiver. In this case the transmitter/receiver are adjusted as described in chapter Radio range and Channels.
6Microphone DM10Change channel:1. Choose Channel in the menu. 2. Choose transmitter or receiver (this applies only to units with both transmitter and receiver). 3. Select a new channel using the menu control.Channel information is also given when the units are paired. FFC (Free Frequency Check) indicates in green the suit-able frequencies for the specific environment. Please note! Switch off your other Digisystem transmit-ters for correct result.FFC dB indicates the noise level in dB for each channel. The higher the (-)value, the lower the risk of interfer-ence. PairTo use a receiver and transmitter together, they must be paired. All transmitters and receivers are default paired at the factory and will work together. NB! To prevent eavesdropping, a new code key must be generated and transmitted between the units by pairing. Transmitting/receiving of pairing information along with a new code can be performed from any Comfort Digisystem unit with a display. To pair units without a display, see section Pairing (via pairing button) for more information. Pairing information or a new code key can be received by several activated units.Pairing (via menu)1. Choose Communication - Pair2. Select Receive info on one unit. Ready to receive pairing info is shown in the display. 3. Select New code on the other unit; select Yes. 4. Generate new code and send info? is shown in the display. Select Yes (Now both the channel and the coding information have been sent, and sound transfer is eavesdrop-secure). 5. To pair another unit into your coded system, select Send info instead on one of your paired units.Pairing (via pairing button)(The only way of pairing units without a display, with the pairing button)You can activate the Pairing function via the pairing but-ton. 1. One brief press of the button opens the Pairing menu. 2. Two brief presses activate the Send info function. 3. One long press activates the Receive info function.Units with both transmitters and receivers built inComfort Digisystem units with both transmitters and receivers built-in can be paired separately. When opening the pairing menu, choose the concerning unit (transmitter/receiver). In units with both transmit-ters and receivers, the pairing button controls the transmitter. The transmitter and receiver are paired separately in these units. The code key is always the same for the transmitter and the receiver when these are built-in in the same unit. The easiest way to get the same code key in the whole Digisystem is to generate a new code key from the combined unit; in that way the built-in receiver gets the same code as the rest of the system. FunctionHere you can adjust the function button. If no choice has been made, the microphone sends continuously the sound it takes up.More settings are possible, see below. The chosen set-ting shows in the display. For more information about the function indicator see More functions.Silence buttonIn this setting you can shut off the microphone so that no sound is sent when you press the function button.Push to talkDM10 only sends when you press the function button.Push/ContIn this setting DM10 works like described above under Push to talk, but by pressing the menu control down (scrolling down) the microphone is switched to send continuously the sound it takes up.This function may be useful when it is impossible to press the function button, e.g. during lectures or pres-entations etc.
7Microphone DM10FCR (Free Channel Request)This function prevents DM10 from sending on frequen-cies which are already taken by other transmitters, e.g. when several DM10 are set on Push to talk.If transmission is not possible, this is shown in the display together with the function indicator. Is the func-tion button pressed in and transmission is not possible, press the function button again and try to send again (it is not enough to keep the button pressed).FCR IndicatorIs the FCR indicator activated, the function indicator shows red if the channel is occupied – even if the func-tion button is not pressed.SettingsPIN codeHere you can turn the PIN code function on and off (selected functions lock). Under the menu item Change PIN you can create your own PIN code.Under the menu item Lock Select, you can select differ-ent types of menu locks:- Mode: Locks all functions in the “Function button” menu (can be combined with the “Pairing” menu item)- Pair: Locks all pairing functions in the unit, as well as the pairing button- All menus: Locks all menus- Hide PIN entry: When the PIN-code is enabled, it is only possible to unlock the menu within 3 seconds after starting the unit, by pressing the menu control.The PIN code is needed to be able to unlock selected functions when PIN code has been activated. If you forget your PIN code, please contact your point of purchase to unlock the unit. ChargeHere you can activate the Auto Power Off function to shut down the unit automatically during charging. If Auto restart is activated, the unit will start up automati-cally when the charger is disconnected or loses power.LanguageFor selection of menu language.NameThe text to be displayed is selected here.

8Microphone DM107) More functionsFunction indicator (LED)The function indicator shows the unit’s status, depend-ing on its setting.On normal operation, the indicator flashes once every three seconds. During charging the indicator shows red. When the charging is completed, the indicator shows green. The indicator stays red even when the battery is fully charged, if the unit is On during charge.When the battery level gets low, the indicator slowly flashes red (check the battery status on the display).Once the unit has been set to receive pairing informa-tion, the indicator flashes green quickly. When receiving pairing information, the indicator shows green for three seconds. When sending pairing information, the indicator flashes red five times. When using the Push to talk-function, the indicator shows green when transmission is possible and the microphone has been activated. If transmission is not possible because the channel is occupied (how to use FCR, see section Function), the function indicator shows red.Is FCR indicator activated, the function indicator shows red when the channel is occupied.When using the function silence button, the indicator shows red.Coloured clipsA number of different coloured clips are available to replace the black cover. This might be useful if you use several microphones at the same time.8) Radio range and channelsThe transmitter and receiver have built-in antennas. The radio range between the units is around 100 feet (30 metres). This may however vary depending on the particular environment you are in. Like all radio systems, Comfort Digisystem communi-cates on specific channels. If you use two transmitters on the same channel or a neighbouring one, there may be interference. Other electronic equipment can also interfere with radio transmissions. The channel that you use in your country is perhaps not permitted abroad. Always get in touch with your hearing aid provider in your country in order to find out which channels are permitted in different countries.Comfort Audio is not liable for unauthorized use of radiowaves, such as, but not limited to: interferences with police communication, or strategic communication, military installations etc.9) Trouble shooting The transmitter and receiver do not startCharge the transmitter and receiver. Remember to press the On/Off button down for 2 seconds to switch the unit on. Check that the charger is connected to the plug socket. Poor speech intelligibilityThe distance between the transmitter and the receiver may be too long. The range is around 30 metres. The distance between the microphone and the person who is talking may also be too long; move the microphone nearer to the person talking. Try to change channel/environment. Poor range and interferenceIn some environments involving, e.g., concrete, iron or sheet metal structures, the range may be reduced. There may also be equipment nearby causing interfe-rence. Change channel.No soundCheck that the transmitter and receiver are set to the same channel. Loud hissing noise (no sound transfer)Check that the units are paired. The unit will not start during chargingDisconnect the charger. Choose Settings - Charge - Auto power off in the menu.
9Microphone DM1010) Battery maintenance The rechargeable products in the Digisystem series are equipped with Li-Po batteries, ie. the same type of batteries used for most mobile phones and laptop computers on the market today. These types of batteries are able to store large amount of energy in relation to their weight and volume. The capacity of Li-Pol batteries diminishes during its life cycle. The battery type has no "memory effect”, which would mean that you need fully discharge the battery before charging to minimize capacity loss. This means that you can just as well charge the battery often and little, as opposed to seldom and much. Special charg-ing circuits in the Digisystem products protect batteries from overcharging.The capacity of the Li-Po batteries deteriorates faster when they subjected to deep discharge. Therefore, all products of the Digisystem are fitted with a function that automatically turns off the product well before deep discharge occurs. Deep discharge may still happen as the battery has a certain self-discharge. A product that is fully or partly charged will with enough time reach a state when the battery deep discharges, unless the charger is connected. To avoid this we recommend that the battery is charged at least every 6 months. 11) Service and warranty Warranty extensionComfort Audio Inc. warrants this product sold to the first end user (buyer) against defects in materials or workmanship for the time period and as set forth below.
