Quad C 823 MKII UHF Conference Table Microphone Unit
Product Information
The Quad C 823 MKII and Quad C 470 are wireless audio
transmission devices designed for transmitting audio signals from
microphones or instruments to amplifiers or active speakers. These
devices operate on specific frequency bands and have a maximum
transmission power of 30 mW. The Quad C 823 MKII operates in the
frequency range of 823 MHz to 832 MHz and 863 MHz to 865 MHz, while
the Quad C 470 operates in the frequency range of 470 MHz to 526
MHz.
The devices utilize frequency modulation (FM) for transmission
and have a total harmonic distortion (THD) of less than 0.5%. They
provide a signal-to-noise ratio of over 102 dB (A). The power is
supplied by two round cell batteries (AA, LR6, 1.5 V) or
corresponding rechargeable batteries.
Product Usage Instructions
- Ensure proper disposal of plastic bags, packaging, etc. to
prevent choking hazards for babies and young children. - Do not allow children to detach small parts from the product as
they may swallow them and choke. - Never let children play unattended with the electrical
devices. - When inserting batteries, ensure proper polarity is observed to
avoid damaging the device or batteries. - If the device is not going to be used for a longer period,
remove the batteries to prevent possible damage from leaking
batteries. - Before using the device, check the regulations regarding the
frequencies used for audio signal transmission in your country and
register the operation if required. - Avoid using liquid cleaners such as benzene, thinners, or
flammable cleaning agents to clean the device.

Safety instructions
Intended use This device is intended to be used for the wireless transmission of audio signals from microphones or instruments to amplifiers or active speakers. Any other use or use under other operating conditions is considered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use.
Danger for children Ensure that plastic bags, packaging, etc. are properly disposed of and are not in the reach of babies and young children. Choking hazard! Ensure that children do not detach any small parts (e.g. knobs or the like) from the product. They could swallow small parts and choke! Never let children play unattended with the electrical devices.
Risk of fire due to incorrect polarity Incorrectly inserted batteries may destroy the device or the batteries. Ensure that proper polarity is observed when inserting batteries.
Possible damage by leaking batteries Leaking batteries can cause permanent damage to the device. Take batteries out of the device if it is not going to be used for a longer time period.
Notes on wireless transmission This device utilizes frequencies that are not harmonized within the European Union (EU) and therefore may only be used in certain EU member states. In all European countries, the frequencies used for the transmission of audio signals are strictly regulated. Before you start, make sure that the frequencies are legitimate in the respective country and check whether the operation must be registered with the responsible authority.
