REGULAR MAINTENANCE SCHEDULE AND TIPS
Daily Maintenance
1. If you row on salt water, rinse the Cox-Box off with fresh water and dry it after every use.
2. Charge the unit whenever it is not in use, but do not leave the unit on
charge indefi nitely. The unit should not be charged for longer than 2
days straight.
3. Slip the metal microphone bayonet on the Cox-Box panel jack
without twisting to lock it. Do not tighten it fully.
4. Inspect the toggle-switch seal for integrity. This is especially
important if you row in salt water and wash your unit regularly.
Once a Month
This maintenance is easy to perform with a Cox-Box Maintenance Kit,
available from NK.
1. Wash the Cox-Box display panel with warm water and mild soap.
Rinse well and dry.
2. Use the drill bit from the Cox-Box Maintenance kit to clean out the metal sockets inside the rubber plug on the
unit. Rotate the bit inside the sockets to dislodge any dirt or debris.
3. Check the inside of the rubber plug on the wiring harness for any dirt. Inspect the wires leading to the plug for
any nicks or cuts. If these exist, contact NK about repairing them.
4. Apply silicone grease to the outside of the rubber plug on the Cox-Box. This helps to minimize the damage done
by repeatedly removing the unit from the boat. Try not to get silicone into the plug itself.
5. Microphone BNC and Panel BNC Connector: You can
greatly
reduce microphone static with regular maintenance
of these connectors. Use the provided small screwdriver to gently spread the contact fi ns in the center of the mic
BNC. The Socket Maintenance kit includes instructions and photos of this step. Use the syringe to run a generous
bead of Nyogel on the inside diameter of the BNC connector on the Cox-Box panel. This grease will transfer to the
mic BNC when it is next connected.
6. Inject a small amount of electrical contact grease (Nyogel) into the sockets on the rubber Cox-Box plug. Connect
the unit to the harness. This will coat the pins with Nyogel and push some Nyogel deeper into the sockets,
protecting them as well.
End of the Season
1. Inspect the toggle switch seal. Perform this step before washing the unit.
2. Wash the Cox-Box with fresh water and dry it carefully.
3. Repeat the cleaning and lubricating steps under “Once a Month” maintenance.
4. Fully charge the Cox-Box then unplug it and store it in a cool, dry place.
