Cox-Vox Maintenance
If you row, cox or coach a coxed boat, you know the CoxVox is an important part of every practice or race. Though designed to perform
in conditions that would destroy most electronics in minutes, there are a few things you can do to help your CoxVox last longer and
perform better. For every waterproof electronic product, the connections are the potential trouble spots. NK sells a complete Cox-Vox
Maintenance Kit with everything needed to make it easy to maintain the connections on your equipment. Follow these steps to keep
your Cox-Vox, Cox-Vox, Microphones & Wiring static-free and reliable for years.

Tips to Help You Get the Most From Your Cox-Vox
· Make sure that the CoxVox is carried by the handle, and NEVER by the microphone. After use, detach the microphone, and do not store the
unit with the mic attached. When attaching the mic to the CoxVox unit, avoid twisting the BNC connection down until it locks. Instead, connect
the mic, and twist the socket just enough to keep it attached.
· Keep your CoxVox clean by rinsing it off after use, ESPECIALLY if you row in salt water.
· Store your CoxVox in a cool, dry place. Avoid leaving it in severe heat or cold (such as the dashboard of a car or an unheated boathouse in
the winter) which can greatly shorten the life of the rechargeable battery pack.
CHARGING
· Recharging: Recharge a regularly-used CoxVox whenever possible to ensure that it will have enough power for the next practice. A fully
drained CoxVox battery pack requires 12 hours on charge to attain maximum capacity. At the end of the season, charge the unit for 12
hours, disconnect the microphone and charger, and store in a cool dry place until ready to use next season.
· Memory Effect: It is not necessary to try to discharge the CoxVox batteries fully between charging - there is virtually no memory effect in
modern nickel cadmium batteries.
· Avoid Overcharging: NK chargers are current-limiting and help prevent battery damage from overcharging. However, leaving the unit
plugged in for many days or weeks (past full charge) may still cause damage. So PLEASE be sure to unplug and store your units during your off
season breaks.
BATTERY LIFE
The life of your battery depends upon many things: the age of the battery pack, the volume and talkativeness of the coxswain, and the extent
of charge. Here are some performance guidelines that should help you plan your CoxVox use.
· A fully charged battery will power a CoxVox with NO audio (volume turned all the way down) for 16 hours.
· With the volume turned all the way up, the battery can supply power for 50 minutes of continuous talk.
· Therefore, with an average volume setting and a coxswain talking less than half the time, a fully-charged CoxVox will provide at least two to
three hours of power, and usually more.
· Having the Coxswain turn the volume down as low as possible will help prolong the battery life.
· If your CoxVox unit is more than three years old, the battery performance will decrease. Simply return the unit to NK for a new battery
replacement. If you're not sure how old your unit is, give the Service Department at NK a call and they can research your unit's serial number to
tell you when it was last serviced.

GENTLY SPREAD GROUND CONDUCTOR "FINS" of the microphone BNC away from the center white insulator using the
small screwdriver. A slight gap between the fins and insulators should remain. Slip the BNC onto the greased Cox-Vox
panel BNC to transfer grease into the body of the microphone BNC. INSPECT cable for intact heat shrink and connection
to BNC. Return to NK for repair if there is visible damage.
REMEMBER! DO NOT lock the BNC ring when plugging in to the Cox-Vox. DO NOT carry the Cox-Vox by the microphone.
DO NOT bend the microphone boom, twist the mouthpiece or twist or yank the cable.
