Inspecting the Toggle Switch
After several years of use, the gray rubber seal around the ON/OFF toggle switch may crack, tear, or otherwise
lose its ability to properly seal the switch. If this happens, water may enter the unit, potentially doing
permanent damage. Examine this seal regularly for any signs of splitting, tearing, or incomplete sealing
around the toggle lever when it is moved to the two extremes. If such damage is noticed, the unit should be
immediately returned to NK.
Battery Life
The life of your battery depends upon many things: the age of the battery pack, the volume and used by the
coxswain and the extent of charge. Here are some performance guidelines that should help you plan your
Cox-Box use.
• A fully charged battery will power a Cox-Box 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
Cox-Box 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.
• A fully drained Cox-Box battery requires 12 hours on charge to attain maximum capacity.
• It is not necessary to try to discharge the Cox-Box batteries fully between charging — there is virtually no
memory effect in modern nickel cadmium batteries.
• If your Cox-Box 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 would like to determine the age and/or repair history of a unit,
please send an e-mail to [email protected]
Avoid overcharging your Cox-Box. 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. Please be sure to unplug and store your units during your off season breaks.
TROUBLESHOOTING
A Cox-Box system consists of four major components: the Cox-Box unit, the microphone, the wiring and the
speakers. All of these components must function for your system to work properly. If you are having a problem
with your system, the best diagnostic tool is to swap out each component, one at a time, with a working
component. When the problem disappears, you know you have pinpointed the trouble area.
