The electrodes on the chest belt naturally wear out after extended use. (See your retailer of www.cateye.com to obtain a replacement.) When there are cracks on the surface or measure- ment error occurs, replace the electrode belt with new one according to the following instruction:
1. Loosen the screws at the back of the transmitter.
2.Remove the spacers. Remove the transmitter from the electrode belt.
3.Fix the transmitter to a new electrode belt. Clean the two contacts before assembling.
NOTE !: If the contacts are dirty, the electrodes may fail to detect heart rate.
4.Put the spacers back and fasten the screws securely.
NOTE !: When replacing the electrode belt, also check the transmitter's battery life.
MAINTENANCE
Daily Care of the MSC-2Dx:
•The contacts on the main unit may be stained by sweat or oils. Wash the contact periodically with mild soapy water.
•If the contacts on the bracket get wet, wipe them dry following the ride. If they get rusty, or if they begin to corrode, it may result in the speed detection error.
•When the main unit or the chest belt heart rate sensor is soiled, wash it with water or clean it with mild soapy water using a soft cloth, and wipe it dry. Do not use benzene, alcohol or other solvent. They will damage the surface and void the warranty.
•Attachment belt absorbs sweat. To keep it clean, wash it occasionally with mild soapy water.
•Periodically check the position of the speed sensor and the magnet to assure they are properly aligned.
