Microphone DM05 55) Getting startedChargingThe Microphone DM05 is chargeable. Charge the DM05 at least two hours before using it the first time. An empty battery is fully charged within two hours. During charging, the function indicator shows red. Once the function indicator shows green, the unit is fully charged and switches to automatic float charging. The unit is automatically switched off when charging. INPUT 5V       220mAConnecting a charger to the Microphone DM05Please 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. Function indicator ON.      The Microphone DM05 is a        microphone for closer range.       It works best within approx.       12 inches (30 cm).      Attach the DM05 to your clothes        using the clip. The DM05 is        supplied with a neck pendant,        which can be connected to the        unit to make sure that you do        not drop it.WARNING! The necklace should not be used if there is a risk of getting stuck, e.g. in a machine or other objects.6) SettingsAs the DM05 does not have a display/menu, the unit's functions are controlled by means of the pairing button. The current function is displayed by the function indica-tor. In addition to the pairing functions (see section Pairing), there is also the facility to activate three modes. To do this, press the pairing button and hold it down immediately after starting up the unit (within two seconds). A selected mode can always be cancelled by switching off the DM05 and starting it up again. Change channelWhen the pairing button is held down for five seconds, the function indicator shows a constant green light. If you release the pairing button when the function indi-cator is green, the Change channel mode is activated. Press the pairing button briefly the number of times corresponding to the desired channel (1-10), see section Radio Range and Channels. After a pause of two seconds, the entry process ends and the selected channel is shown by the same number of green flashes in the function indicator. Change codeIf the pairing button is instead held down for ten sec-onds, the function indicator will switch to a red light. If you release the pairing button when the function indi-cator is red, Change code mode is activated. Press the pairing button twice in quick succession to generate a random code, and at the same time the pair-ing information is transmitted (make sure that other Digisystem units to be paired are activated to receive pairing information). Five red flashes in the function indicator confirm that the pairing information (channel and code) has been sent. Change channelChange codeFactoryreset0 sec 5 sec 10 sec 15 sec 20 sec
Microphone DM05 6Factory resetIf the pairing button is instead held down for 20 seconds, the function indicator will switch to an alternating red and green light. The Factory reset mode is now acti-vated. To perform a factory reset, press the pairing button once quickly. The function indicator flashes the number of times corresponding to the channel, see section Radio Range and Channels. The channel and code are now reset to the factory set-tings. 7) PairMicrophone DM05 must be paired using the pairing but-ton, see section Pairing (via pairing button).PairingTo 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 Digisys-tem unit with a display. To pair units without a display, see sections Pairing (via pairing button). 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. 8) More functionsFunction indicator (LED)The function indicator shows the unit’s status depending on its setting. When the DM05 starts, the function indicator shows which channel is selected (1-10) by flashing green 1-10 times. If another channel has been paired in, this is indi-cated by the green lamp lighting for four seconds when the unit is started up. On normal operation the indicator flashes every other second. During charging the indicator shows red.  When the charging is completed, the indicator shows green. When the battery gets low, the indicator flashes red every other second.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 four seconds. When sending pairing information, the indicator flashes red five times. A constant green light indicates Change channel mode.A constant red light indicates Change code mode.An alternating red/green light indicates Factory reset mode.
Microphone DM05 79) 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.10) 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. 11) Battery maintenance The rechargeable products in the Digisystem series are equipped with Li-Pol 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-Pol 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.
