Cox-Box Maintenance
If you row, cox or coach a coxed boat, you know the CoxBox 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 CoxBox last longer and perform better. For every waterproof
electronic product, the connections are the potential trouble spots. NK sells a complete Cox-Box Maintenance Kit with everything needed to make it easy to
maintain the connections on your equipment. Follow these steps to keep your Cox-Box, Cox-Vox, Microphones & Wiring static-free and reliable for years.

Tips to Help You Get the Most From Your Cox-Box
· Make sure that the CoxBox 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 CoxBox 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 CoxBox clean by rinsing it off after use, ESPECIALLY if you row in salt water.
· Store your CoxBox 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 CoxBox whenever possible to ensure that it will have enough power for the next practice. A fully drained CoxBox
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 CoxBox 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 CoxBox use.
· A fully charged battery will power a CoxBox 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 CoxBox 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 CoxBox 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.

Microphone - MONTHLY or As Needed
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-Box 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-Box. DO NOT carry the Cox-Box by the microphone. DO
NOT bend the microphone boom, twist the mouthpiece or twist or yank the cable.
