CARING FOR YOUR COX-VOX SYSTEM
Nielsen-Kellerman equipment is designed, built and tested to withstand the rigors of everyday use, but it is
not
invincible and it can be damaged. The following information is intended to help you maintain your equipment
and prevent unnecessary repairs.
Charging
• Place the unit on charge whenever it is not in use, but do not leave the unit charging indefi nitely. The unit
should never be charged continuously for longer than 2 days.
• If the battery light comes on, be sure to charge the unit for at least 12 hours.
• Do not continue to use a unit with the low battery warning light illuminated. Repeated use with the low
battery light on may damage the batteries and unit.
• Under normal conditions, a fully charged battery should last at least 4 hours. If your unit is not providing
this much operational time, it may be time to return it to NK to have new batteries installed. We expect our
batteries to need replacement after three years of normal full-season use.
Care of Your Microphone
Your microphone is shipped attached to a headband and ready for use. The microphone is fully waterproof, and
may be fully immersed, but it will not fl oat on its own. Unless it is attached to a Cox-Vox, the microphone will
sink. Microphones should be treated with care.
• Do not attempt to bend the aluminum boom or twist the mouthpiece.
• Do not drop the microphone.
• Do not yank or pull on the microphone cable when
disconnecting from the Cox-Vox.
• Do not tighten the bayonet connector on the microphone to the
panel jack on the Cox-Vox. Just slip it into place.
• Do not carry the Cox-Vox by the microphone.
Often, when a customer attempts to replace a microphone BNC, the
replacement connector pin is of an incorrect diameter and damages
the center conductor of the Cox-Vox panel mount BNC.
NOTE: The NK warranty covers defects in materials and workmanship. It DOES NOT cover damage
caused by abuse, misuse, or attempts to repair the microphone on your own.

Additional Information
Never attempt to repair the Cox-Vox unit yourself. The units are specially sealed to make them watertight.
Breaking this seal often causes very expensive damage and will void the warranty. The only accessory
that we will repair is the microphone. We do encourage and will support experienced individuals to
repair and maintain wiring harnesses and speakers.
