The channel indication starts flashing. 6 Press the + or button repeatedly to select a channel. 7 Press the SET button to enter the channel. Note 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 Remote When the transmitter is paired with the receiver, the transmission channel of the transmitter is set to the receiving channel on the receiver automatically. For details, seePairing with a receiver (page 7). Using Cross Remote This transmitter 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 transmitter 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 transmitter and the receiver using the RF REMOTE function. Pairing must be done first before the wireless remote control function can be used. Note 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 (page 6). Pairing with a receiver Pairing links the transmitter with the receiver which the wireless remote control function is to be used. When the transmitter has been paired with a receiver through the receiver operation, turning on the transmitter while holding down the button establishes the pairing immediately. To carry out pairing through menu operations on the transmitter, do the following. 1 Set the receiver to be used for controlling the transmitter to pairing mode. For details, refer to the operating instructions supplied with the receiver. 2 Press the + or button repeatedly until the RF REMOTE indication is displayed. 3 Hold down the SET button until the item to be set flashes. 4 Press the + or button repeatedly to select PAIRING. 5 Press the SET button to enter. The transmitter sends a pairing request to the receiver which is on pairing mode. Before established pairing, if you press any operation key on the transmitter, pairing mode will be cancelled. When pairing has been established, the wireless remote control condition level (indicated by

) 7 goes up, RF REMOTE turns on, and the remote control function becomes operative. To use the Cross Remote with a previous pairing In the RF REMOTE indication, select ON. Notes

When you set RF REMOTE to ON, the transmitter will communicate with the receiver to which it was previously paired. To use the wireless remote control function with another receiver, you must perform the pairing procedure for that receiver.

Multiple transmitters cannot be paired with the same receiver.

If you reset all parameters by using the FACTORY PRESET function (see page 14), the pairing setting of the transmitter is also cleared. The following transmitter settings can be done from the remote control:

Transmitter name setting

Frequency band/group/channel selection

RF transmission power setting

MIC/LINE setting and attenuator setting for audio input level

Low-cut filter setting

Power save setting

Resetting accumulated use time

Audio codec mode setting

Internal signal setting

POWER switch lock setting For details on menu operation, see Setting Menus

(page 10). 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 Remote In the RF REMOTE indication, select OFF. Notes on the Cross Remote The wireless remote control function on the transmitter uses the 2.4-GHz band and may thus be subject to interference from other devices.

When pairing fails (Pairing fail is displayed), successful communication between the transmitter and the receiver has not occurred within a given amount of time. Pairing may be harder to do when another receiver is engaged in pairing nearby.

When it becomes hard to use the remote control, the remote control may be improved by switching the wireless remote control function off, then on again in the RF REMOTE display, then re-pairing with the transmitter (change to a channel with less interference). Using the Encrypted Transmission Function The unit is capable of transmitting encrypted signals to prevent unwanted surveillance. To use the function, select one of the following encryption modes. Encryption key modes (SECURE KEY / AES256):

An encryption key is automatically generated by the transmitter and used by both the transmitter and receiver in these one-to-one encrypted transmission modes. The SECURE KEY mode is compatible with first and second generation DWX-series devices. The AES256 mode uses AES 256-bit encryption for a higher level of security in transmissions. Password mode (PASSWORD): A user-created password of up to 8 characters can be set for multiple transmitters (this unit) and receivers in this mode. This allows encrypted transmission within a group. Note Make sure that encryption mode settings are identical on both the transmitter (this unit) and the receiver. Using the encryption key modes

(SECURE KEY / AES256) Use these modes for one-to-one encrypted transmission between one transmitter (this unit) and one receiver. To enable encrypted transmission in these modes, an encryption key that cannot be read from the outside is automatically generated by the unit, and the key is transmitted to the receiver via the wireless remote control function. A new encryption key for the transmitter (this unit) and receiver is automatically generated for each key transmission, resulting in highly secure communication. The encryption key for the transmitter (this unit) and receiver is retained when the unit is turned off, allowing you to resume the same encrypted transmission the next time you turn the unit on. 1 Prepare the transmitter (this unit). 1 Hold down the SET button in the units ENCRYPTION screen until the setting value blinks. 2 Use the + and buttons to select SECURE KEY or AES256, and press the SET button. 2 Prepare the receiver. Set the receiver that will receive the encryption key to SECURE KEY or AES256. For details on receiver operations, refer to the receivers operating instructions. 8 3 Exchange the encryption key. On the receiver side, select REMOTE (wireless remote) as the encryption key exchange method, and perform encryption key exchange. REMOTE cannot be selected when the wireless remote control function is disabled. Note If the receiver does not support AES256 mode, select SECURE KEY. For details, refer to the receivers operating instructions. The unit searches for the receiver with which it is paired. When the receiver is found, the encryption key is exchanged, and encrypted transmission begins. Using the password mode

(PASSWORD) Use this mode for encrypted transmissions between multiple paired transmitters (this unit) and receivers. When the same user-created password is set on both the transmitters (this unit) and the receivers, the audio signal can be decoded. This mode is useful when you want to operate multiple transmitters (this unit) and receivers as a group, or receive transmissions from a single transmitter

(this unit) on multiple receivers at the same time. 1 Hold down the SET button in the units ENCRYPTION screen until the setting value blinks. 2 Use the + and buttons to select PASSWORD, and press the SET button. 3 Enter a password of up to 8 characters on the unit. For details on how to enter the password, see the procedure described in Unit name setting (NAME)

(page 10). 4 Set the encrypted transmission setting on the receiver to PASSWORD. 5 Set the same password that you set for the unit on the receiver. For details on receiver operations, refer to the receivers operating instructions. Note We recommend changing the password periodically.

The power is repeatedly turned ON/OFF (screen turns on/off) even when the POWER switch is ON. The batteries drain quickly. Interruptions in the reception occurs. There is no sound. The sound is weak. Manganese batteries are being used. The transmitter is being used under cold conditions. The transmitter is too far from the receiver. The transmission power setting is set to L:

1mW. The channel setting on the transmitter is different from that on the receiver. The setting of the encrypted transmission function on the receiver is different from that on the transmitter. The audio codec mode settings on the receiver and transmitter do not match. The audio input level of the transmitter is set to LINE or the attenuation level is too high. There is distortion in the sound. The attenuator is set too low for the audio input level of the transmitter. The bass is weak. The frequency of the low-cut filter is set too high. There is too much bass. The microphone connected to the transmitter produces excessive bass because the frequency response of the transmitter extends into the low 20-Hz range. The POWER switch is locked. The power does not turn off even though the POWER switch is turned to OFF. Wireless remote control is not possible. Pairing has not been established between the transmitter and receiver. The receiver is too far from the transmitter for communication to occur. The display is too dark. The RF output power cannot be configured. The transmitter that was paired with the receiver has been paired with another receiver. The display brightness is set to low. The maximum RF output power function may be set to limit the RF output power. 17 Use alkaline batteries. The batteries drain quickly under cold conditions. Decrease the distance to the receiver and check the reception. Increase the transmission power (see page 12). Use the same channel setting on both the transmitter and receiver. Confirm that the setting of the encrypted transmission function is the same on both the transmitter and the receiver (see page 8). Configure the same audio codec mode setting for both the receiver and transmitter (see page 12). If a microphone is connected to the transmitter, set the audio input to MIC (see page 12). While monitoring the audio input level meter, set the attenuator to an appropriate level. While monitoring the audio input level meter, set the attenuator to a level that does not produce distortion. While monitoring the sound, decrease the low-cut filter frequency to a level that produces the proper sound quality (see page 10). Use the low-cut filter to cut the bass (see page 10). Turn off the LOCK function (see page 11). Carry out pairing (see page 7). Check the wireless remote control condition level. If it is low, decrease the distance between the transmitter and the receiver (see page 5). On the receiver, carry out pairing again with the transmitter that you want to control. Adjust the brightness of the display (see page 13). Check and adjust the setting. the antenna of a receiver for up to 10 channels, and at least 6 meters (20 feet) away for 11 or more channels.

When a mixture of digital and analog wireless microphones is being used, keep the transmitter at least 6 meters (20 feet) away from the antenna of a receiver.

This system should be kept at least 100 meters (328 feet) away from any analog wireless systems using the same frequency when both are being used in a wide area with no walls or obstructions.

If you experience noise, increase the distance between the transmitter and receiver or decrease the transmission power on the transmitter. Note on microphone and transmitter combinations It is recommended that you use the ECM-90BC, ECM-

The digital wireless microphone system product must be used within a temperature range of 0 C to 50 C (32 F to 122 F).

Operating the transmitter near electrical equipment

(motors, transformers, or dimmers) may cause it to be affected by electromagnetic induction. Keep the transmitter as far from such equipment as possible.

The presence of the lighting equipment may produce electrical interference over the entire frequency range. Position the transmitter so that interference is minimized.

To avoid degradation of the signal-to-noise ratio, do not use the transmitter in noisy places or in locations subject to vibration, such as the following:

- near electrical equipment, such as motors, transformers or dimmers

- near air conditioning equipment or places subject to direct air flow from an air conditioner

- near public address loudspeakers

- where adjacent equipment might knock against the tuner Keep the transmitter as far from such equipment as possible or use buffering material. On cleaning

If the transmitter is used in a very humid or dusty place or in a place subject to an active gas, clean its surface as well as the connectors with a dry, soft cloth soon after use. Lengthy use of the transmitter in such places or not cleaning it after its use in such places may shorten its life.

Clean the surface and the connectors of the transmitter with a dry, soft cloth. Never use thinner, benzene, alcohol or any other chemicals, since these may mar the finish. Notes on simultaneous multi-

channel operation

Keep the microphone at least 30 cm (11 7/8 inches) away from another transmitter/microphone. When the distances between transmitters need to be closer than the distances above, use a grouping system for multi-channel systems that include both digital wireless and analog wireless devices. For details, refer to Sony Digital Wireless Microphone System Frequency Lists on the supplied CD-ROM.

When only digital wireless microphones are being used, keep the transmitter at least 4 meters (13 feet) away from 18 Operating temperature 0 C to 50 C (32 F to 122 F) Note When used in locations with an ambient temperature of 45 C (113 F) or higher, make sure the unit does not come into direct contact with your skin, as it may cause burns due to high temperature.
