I lost my user manual and want to stop the "Filter" needed indicator on my Honeywell T8600D Chronotherm IV Deluxe Programmable Thermostat. The filter was recently changed, so a new one is not needed. How do I stop "Filter" from flashing?

"HVAC1000" had earlier asked for the exact model number. Hope you can now reply. Thanks!

See page 7 for starters then read instructions on how to reset to zero 0.
