7Setting the Transmission ChannelThe microphone provides groups of interference-free channels. When using multiple microphones and transmitters at the same time (simultaneous multi-channel operations) within the same area, selecting the same group and using a channel within that group can prevent signal interference.To set the transmission channel on the microphone, first you select the group and channel using the RF indicator and scanning functions on the receiver. Next you set the group and channel parameters to match the setting on the receiver.• Certain transmission channels cannot be used with the wireless remote control function.• “(INCOMPATIBLE WITH RF REMOTE)” will slide across the display during group/channel selection for transmission channels that cannot be used with the wireless remote control function.• When a transmission channel that cannot be used with the wireless remote control function is selected, “RESTRICTED BY GP/CH SETTING” appears on the RF REMOTE screen and the wireless remote control function cannot be used. When using the wireless remote control function, select transmission channels for which “(INCOMPATIBLE WITH RF REMOTE)” does not appear during group/channel selection.Selecting the Group/Channel• Before doing this procedure, use the BAND function (see page 12) to set the microphone to the bandwidth of the receiver you are using.• The setting for this function cannot be changed during actual signal transmission. Set the microphone group (GP) and channel (CH) as follows:For details on groups and channels, refer to “Sony Digital Wireless Microphone System Frequency Lists” on the supplied CD-ROM.For details on menu operation, see “Basic Menu Operations” on page 11.1Turn off the power, and then while holding down the SET button, turn the power on.The signal transmission stops.2Press the + or – button repeatedly until the GP/CH indication is displayed.3Hold down the SET button until the item to be set flashes.4Press the + or – button repeatedly to select a group.5Press the SET button to enter the group.The channel indication starts flashing.6Press the + or – button repeatedly to select a channel.7Press the SET button to enter the channel. To start signal transmission with the selected channel, turn off the power and then turn it on again.To set the group/channel using the pairing mode of the Cross RemoteWhen the microphone is paired with the receiver, the transmission channel of the microphone is set to the receiving channel on the receiver automatically.For details, see“Pairing With a Receiver” on page 8.NotesNotesNote

8Using the Cross RemoteThis microphone is equipped with a wireless remote control function that can be used to set the parameters (low-cut filter, attenuation operation, power save mode, etc.) of the microphone through the receiver or other devices. This function makes it easier to operate and manage the microphone system while in the field.This wireless control is 2.4 GHz IEEE802.15.4 compliant and has no effect on the RF band of digital wireless audio.This function is activated when pairing is established between the microphone and the receiver using the RF REMOTE function. Pairing must be done first before the wireless remote control function can be used.If “RESTRICTED BY GP/CH SETTING” appears on the RF REMOTE screen, the wireless remote control function cannot be used. To use the wireless remote control function, select a different transmission channel.For details on how to change the transmission channel, see “Setting the Transmission Channel” on page 7.Pairing With a ReceiverPairing links the microphone with the receiver which the wireless remote control function is to be used.When the microphone has been paired with a receiver through the receiver operation, turning on the microphone while holding down the – button establishes the pairing immediately.To carry out pairing through menu operations on the microphone, do the following.1Set the receiver to be used for controlling themicrophone to pairing mode.For details, refer to the operating instructions supplied with the receiver.2Press the + or – button repeatedly until the RFREMOTE indication is displayed.3Hold down the SET button until the item to be setflashes.4Press the + or – button repeatedly to select PAIRING.5Press the SET button to enter.The microphone sends a pairing request to the receiver which is on pairing mode.Before established pairing, if you press any operation key on the microphone, pairing mode will be cancelled.When pairing has been established, the wireless remote control condition level (indicated by ) goes up, RF REMOTE turns on, and the remote control function becomes operative.When “Pairing fail” is displayed• Successful communication between the microphone and the receiver did not occur within a given amount of time.Perform pairing again.• Pairing has been performed with the grip open. When the internal antenna is covered with the grip, pairing may not be carried out. After setting the microphone ready forpairing in step 5 above, be sure to close the grip.To use the Cross Remote with a previous pairingIn the RF REMOTE indication, select ON.• When you set RF REMOTE to ON, the microphone willcommunicate with the receiver to which it waspreviously paired. To use the wireless remote controlfunction with another receiver, you must perform thepairing procedure for that receiver.• Multiple microphones/transmitters cannot be pairedwith the same receiver.• If you reset all parameters by using the FACTORYPRESET function (see page 15), the pairing setting ofthe microphone is also cleared.The following microphone settings can be done from the remote control:• Microphone name setting• Frequency band/group/channel selection• RF transmission power setting• Attenuator for the audio input setting• Low-cut filter setting• Power save setting• Resetting accumulated use time• Audio codec mode setting• Internal signal setting• POWER switch lock settingFor details on menu operation, see “Setting Menus” on page 12.To perform remote control, the receiver must be equipped with a control function for the setting you want to control. For details, refer to the operating instructions supplied with the receiver.To cancel the Cross RemoteIn the RF REMOTE indication, select OFF.Notes on the Cross RemoteThe wireless remote control function on the microphone uses the 2.4-GHz band and may thus be subject to interference from other devices.NoteNotes

9• When pairing fails (“Pairing fail” is displayed),successful communication between the microphone andthe receiver has not occurred within a given amount oftime. Pairing may be harder to do when another receiveris engaged in pairing nearby.•When it becomes hard to use the remote control, theremote control may be improved by switching thewireless remote control function off, then on again in the RF REMOTE display, then re-pairing with themicrophone (change to a channel with less interference).Using the Encrypted Transmission FunctionTo prevent hacking of the signal, the microphone scrambles the signal during transmission. To use this function, select one of the following encrypted transmission modes:Secure key mode: An encryption key that is automatically generated by the microphone is used by both the microphone and receiver in this one-to-one encrypted transmission method.Password mode: You choose a password of up to eight characters that can be set for multiple microphones/transmitters and receivers. This enables encrypted transmission within a group. Make sure the same mode is set on the microphone/transmitter and receiver.Using Secure Key Mode (SECURE KEY)Use this mode for one-to-one encrypted transmission between one microphone and one receiver.An encryption key that cannot be read from the outside is automatically generated by the microphone. This key is transmitted to the receiver through a USB connection or the RF REMOTE function, enabling encrypted transmission to take place.The encryption key used by the microphone and receiver is newly generated for each key transmission, resulting in highly secure communication.The encryption key used between the microphone and the receiver is saved when the power is turned off, so the encrypted transmission can be resumed the next time the power is turned on.1Preparing the microphone (this unit)1Hold down the SET button until the item to be set flashes in ENCRYPTION indication on the microphone.2Press the + or – button repeatedly to select SECURE KEY, and then press the SET button.2Preparing the receiverSelect SECURE KEY on the receiver that receives the encryption key.For details on receiver operations, refer to the operating instructions supplied with the receiver.3Exchanging the encryption keyOn the receiver, select USB or REMOTE (wireless remote) as the method for encryption key exchange.When the RF REMOTE function is off, REMOTE cannot be selected.Note

10 When the receiver does not support encryption key exchange through USB connection, select REMOTE.For details on the receiver, refer to the operating instructions supplied with the receiver.When you select USB: Connect the microphone to the receiver with the USB cable (not supplied) and USB adapter cable (supplied).For details on receiver operations, refer to the operating instructions supplied with the receiver.When you select REMOTE: The microphone searches for a receiver that it has been paired with. After the microphone detects the receiver, the microphone exchanges the encryption key with receiver and encrypted transmission begins.Using Password Mode (PASSWORD)Set this mode when multiple microphones/transmitters are paired with multiple receivers for encrypted transmission.If both microphones/transmitters and receivers are set with the same user-designated password, the audio signal can be decoded. This mode is useful when multiple microphones/transmitters and receivers are used as a single group, or when the audio signal from one microphone/transmitter is received by multiple receivers at the same time.1Hold down the SET button until the item to be set flashes in the ENCRYPTION indication on the microphone.2Press the + or – button repeatedly to select PASSWORD, and then press the SET button.3Input a password of up to eight characters on the microphone.To enter a password, use the procedure described in “Naming of Microphone (NAME)” on page 12.4Set the encrypted transmission function setting on the receiver to PASSWORD.5Set the same password that was set on the microphone.For details on receiver operations, refer to the operating instructions supplied with the receiver. It is recommended that you change the password periodically.NoteUSB cable (not supplied)USB adapter cable (supplied)Note

For any problems with the receiver, refer to the operating instructions supplied with the receiver. If the problem persists, consult your Sony dealer.Symptom Meanings RemedyThe microphone does not turn on.The batteries are inserted backwards in the battery compartment.Reinsert the batteries with the correct orientation (see page 5).The batteries are exhausted. Replace the batteries with new ones.The batteries drain quickly.Manganese batteries are being used. Use alkaline batteries.The microphone is being used under cold conditions.The batteries drain quickly under cold conditions.Interruptions in the reception occurs.The microphone is too far from the receiver. Decrease the distance to the receiver and check the reception. The transmission power setting is set to “L: 1mW”.Increase the transmission power (see page 12).There is no sound. The channel setting on the microphone is different from that on the receiver.Use the same channel setting on both the microphone and receiver.The setting of the encrypted transmission function on the receiver is different from that on the microphone.Confirm that the setting of the encrypted transmission function is the same on both the microphone and the receiver (see page 9).The audio codec mode settings on the receiver and transmitter do not match.Configure the same audio codec mode setting for both the receiver and transmitter (see page 13).The sound is weak. The attenuator is set too high for the audio input level of the microphone.While monitoring the audio input level meter on the microphone or the receiver, set the attenuator to an appropriate level (see page 12).There is distortion in the sound. The attenuator is set too low for the audio input level of the microphone.The bass is weak. The frequency of the low-cut filter is set too high.While monitoring the sound, decrease the low-cut filter frequency to a level that produces the proper sound quality (see page 13).There is too much bass. The microphone produces excessive bass because the frequency response of the microphone extends into the low range.Use the low-cut filter to cut the bass (see page 13).The power does not turn off even though the POWER switch is turned to OFF.The POWER switch is locked. Turn off the POWER SW LOCK function (see page 14).Wireless remote control is not possible.Pairing has not been established between the microphone and receiver.Carry out pairing (see page 8).The receiver is too far from the microphone for communication to occur.Check the wireless remote control condition level. If it is low, decrease the distance between the microphone and the receiver (see page 5).The microphone that was paired with the receiver has been paired with another receiver.On the receiver, carry out pairing again with the microphone that you want to control.The USB keyboard does not work.You are using a USB keyboard that is not compatible with the microphone.Check the conditions for using a USB keyboard with the microphone (see page 11).The display is too dark. The display brightness is set to low. Adjust the brightness of the display (see page 14).

18Important Notes on OperationNotes on Using the Microphone• The digital wireless microphone system product must be used within a temperature range of 0 °C to 50 °C (32 °Fto 122 °F).• Operating the microphone near electrical equipment(motors, transformers, or dimmers) may cause it to beaffected by electromagnetic induction. Keep themicrophone as far from such equipment as possible.• The presence of the lighting equipment may produceelectrical interference over the entire frequency range.Position the microphone so that interference isminimized.• To avoid degradation of the signal-to-noise ratio, do notuse the microphone in noisy places or in locationssubject to vibration, such as the following:- near electrical equipment, such as motors,transformers or dimmers- near air conditioning equipment or places subject todirect air flow from an air conditioner- near public address loudspeakers- where adjacent equipment might knock against thetunerKeep the microphone as far from such equipment as possible or use buffering material.On Cleaning• If the microphone is used in a very humid or dusty placeor in a place subject to an active gas, clean its surface aswell as the connectors with a dry, soft cloth soon afteruse. Lengthy use of the microphone in such places or notcleaning it after its use in such places may shorten itslife.• Clean the surface and the connectors of the microphonewith a dry, soft cloth. Never use thinner, benzene,alcohol or any other chemicals, since these may mar thefinish.Notes on Simultaneous Multi-Channel Operation• Keep the microphone at least 30 cm (11 7/8 inches) awayfrom another transmitter/microphone.When the distances between transmitters and microphonesneed to be closer than the distances above, use a groupingsystem for multi-channel systems that include both digitalwireless and analog wireless devices.For details, refer to “Sony Digital Wireless MicrophoneSystem Frequency Lists” on the supplied CD-ROM.• When only digital wireless microphones are being used,keep the microphone at least 4 m (13 feet) away from the antenna of a receiver for up to 10 channels, and at least 6 m (20 feet) away for 11 or more channels.• When a mixture of digital and analog wirelessmicrophones/transmitters is being used, keep themicrophone at least 6 m (20 feet) away from the antennaof a receiver.• This system should be kept at least 100 m (328 feet)away from any analog wireless systems using the samefrequency when both are being used in a wide area withno walls or obstructions.• If you experience noise, increase the distance betweenthe microphone and receiver or decrease thetransmission power on the microphone.To prevent electromagnetic interference from portable communication devicesThe use of portable telephones and other communication devices near the DWM-02N may result in malfunction and interference with audio signals. It is recommended that portable communication devices near the DWM-02N be turned off.
