SAFETY RECOMMENDATIONS

CAUTION

DO NOT OPEN THE HOUSING

SHOCK HAZARD

The exclamation point triangle is used to alert the user to important operating or maintenance instruc-

tions

The lightning bolt triangle is used to alert the user to the risk of electric shock

Accordance with the requirements of UK standards

Class I protection: Connect only to an earthed mains outlet

The product is for indoor use only

• This device is only allowed to be operated with an alternating current of max. 110-240V~ 50/60Hz and was

designed for indoor use only.

• This is a wireless communication system, use UHF band carrier frequency. We recommend that users

consult local radio management committee to choose the appropriate and legally available frequency, in

order to avoid RF interference

• If the units demonstrate any problems, such as abnormal sound, smoke, heat from or damage to power

cables, disconnect the power plug from the outlet and contact your sales representative.

• Operate the device only after having familiarized yourself with its functions. Do not permit operation by

• Do not place any obstructions around the microphone units

• When the microphone units are too close together, high sound volume may cause acoustic feedback, In

this case, increase the space between the conference units or turn down the volume

• After the battery has been removed and replaced, conrm that the power LED turns off
