ST621TX INSTRUCTION MANUAL
Repeat this action until you have entered
the entire telephone number. After
entering and confirming the last digit
with the OK key, store the telephone
number by pressing the Arrow key
Once set as described, the SERVICE
indicator will appear on the display 30
days before the set date. At seven days
before the set date, the SERVICE indicator
will flash and the bottom section of the
display will alternate between displaying
the current mode (AUTO or MANUAL),
and the telephone number previously
entered.
Once the SERVICE date has been reached, the system
will only operate at the temperature that was previously
set in SERVICE mode. The display will no longer display
the operating mode, only the telephone number that
has been entered and the SERVICE indicator (which will
continue to flash).
To enter the SERVICE menu, press the OK or Arrow keys, and enter the code you originally set to access
SERVICE mode. Once back in SERVICE mode, you can edit the telephone number, set a new servicing
date, or turn SERVICE mode ON or OFF in exactly the same way as described earlier.
