Using the Encrypted Transmission Function

To 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.
Note
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.

Important Notes on Operation

Notes on Using the Microphone

• 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 microphone near electrical equipment (motors, transformers, or dimmers) may cause it to be affected by electromagnetic induction. Keep the microphone as far from such equipment as possible.
• The presence of the lighting equipment may produce electrical interference over the entire frequency range. Position the microphone so that interference is minimized.
• To avoid degradation of the signal-to­noise ratio, do not use the microphone 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 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 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 microphone 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 microphone with a dry, soft cloth. Never use thinner, benzene, alcohol or any other chemicals, since these may mar the finish.
Notes on Simultaneous Multi­Channel Operation
• Keep the microphone at least 30 cm (11 7/ inches) away from another transmitter/ microphone. When the distances between transmitters and microphones 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 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 wireless microphones/transmitters is being used, keep the microphone at least 6 m (20 feet) away from the antenna of a receiver.
• This system should be kept at least 100 m (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 microphone and receiver or decrease the transmission power on the microphone.
