CHAPTER 4
| MAINTENANCE
Cleaning
It is very important and necessary to schedule periodic cleaning of the ENV-112CM Retractable
Response Lever to ensure reliable operation and response detection. This should be done once a
week or once a month based on use, to reduce buildup of dander, dust, or debris which can lead
to unreliable operation and response detection. Humid environments may require more
frequent cleaning. Med-Associates recommends that sticky substances such as sucrose, peanut
butter, etc. should not be placed on the paddles of retractable levers as it can cause damage to
mechanical and electrical components.
NOTE: Items returned for repair that have not been properly cleaned will be not covered
under warranty. Please contact Med Associates (see Appendix A | Contact Information) if
you would like to send your Retractable Response Lever to us for a routine cleaning
service. We will be happy to send you a quote for this service.
