Maintenance
Reader Unit Maintenance
The reader unit requires little maintenance except to charge the batteries as necessary and to ensure the
connectors are kept clean and dry. When the voltage from the battery pack falls below 11.0 volts, the reader unit
will display the warning message on the LCD display. If the unit is not recharged the voltage will still drop and the
instrument will then automatically shut down, although any data stored in the memory will be retained. When
this occurs, the only way to restart the instrument is to recharge the batteries. Ensure that the connector caps are
secured onto any connectors which are not in use.
Battery Replacement
The model 801B battery is a rechargeable battery. Contact Yeo-Kal Electronics for information. If it needs
changing return it to factory or a qualified agent.
Probe Maintenance
There is little maintenance required for the probe except keeping the optics clean with a soft cloth. Store the
probe dry.
NEVER TRY TO REMOVE THE ELECTRONICS FROM THE HOUSING AS IT WILL VOID ANY WARRANTY.
