Message in Alarm History
After putting a battery into your new pump, a message “RfBad” may
appear in your alarm history screen. (The pump does not alarm in
this case.) The “RfBad” message will be the first entry dated
Jan 1. Please disregard the message in your alarm history. The
pump is operating normally. You do not need to call the 24-hour
Product Help-line to report this message. At any time, if you want
to test your pump's performance, perform a Selftest. Refer to your
User Guide for instructions for performing a Selftest.
