13. SPECIAL RESET PROCEDURES
Sometimes it will necessary to reset the transmitter / receiver units to their factory
defaults, or perhaps just the Bluetooth® module to its factory defaults as well.
As both procedures are extremely dangerous for a running WiSpeak system when
applied without the proper permissions, and/or without the right knowledge of their
consequences, we beg you ask your official WiSpeak installer / distributor to carry them
out.
14. CLEANING
The casing should not be cleaned with solvents or abrasive materials since they can
damage the screen printing. To clean the product, please used a cloth dampened with a
mild liquid detergent and water, and wipe it off with a dry and clean cloth. Be careful that
water never gets into the unit through its holes.
