4.1. 

Operator Maintenance Program 

The following log is recommended to be maintained by the user or by operator on daily /Weekly 
basis 

General Precautions 

• 

DO NOT autoclave, gas sterilize or immerse the electrical parts of the in liquid. 

• 

The person operating the Pony graphic should not perform any servicing except as 
specifically stated in the Pony graphic User's Manual. 

• 

If the Pony graphic fails to respond as described, DO NOT use it until you have 
corrected the situation. Refer to the trouble-shooting section of this manual for more 
detailed discussion. 

• 

Always turn the PONY graphic off before cleaning or servicing. 

• 

DO NOT immerse any electrical part (i.e. Optoelectronic transducer) in water or any 
liquid. 

• 

DO NOT touch any exposed wiring or conductive surface while the cover is off and the 
system is running if using a grounding wrist strap. 

• 

Use insulated tools when touching the components of the PCBs. 

• 

Electrostatic Discharge through the PCBs will damage the components of the system. 
Handle all circuit boards (replacements and defectives) by their non conductive edges 
and use anti-static containers when transporting them. Before servicing the equipment, 
ground yourself and the tool to discharge any accumulated static charge by wearing a 
static control wrist strap. 

• 

Check Power Supply Adapter voltage before connecting the AC main power. 

• 

Replace fuses ONLY with the same type and rating ones.
