There is one three-position slide switch inside the battery
compartment. The user can enable the probe by selecting
the position of the switch. When the switch is in the “
L
”
position, the left probe is working and the right sensor
buttons are functionless. When the switch is in the “
R
”
position, the right probe is working and the left sensor
buttons are functionless. When the switch is in the middle
position, both probes are working and all buttons are
functional. The probe should be plugged into the unit all
the time as long as it is enabled. Position of the slide switch
should be in the correct position before battery is installed.
Changing the slide switch position requires resetting the
unit by re-installation of battery or pressing the system reset
button, which is also inside the battery compartment.
7.
If the probe is enabled (through the slide switch) and is
unplugged during unit powering up or setup, the alarm will
beep and EEE will be displayed in the corresponding probe
temp display area. The unit cannot be set up until the
probe is plugged in again.
8.
During normal operation, when the probe is unplugged,
the EEE temp and duration of the probe being unplugged
will be recorded. The alarm will beep during the probe is
unplugged. After the probed is inserted again, the
operation for that probe resumes.
9.
During the time the probe is plugged-in or unplugged, the
temperatures recorded at that moment may not be
accurate. If these temperatures meet the temp high/low
settings, they will be written to the alarm records (together
with the “EEE” alarm record), and the users need to filter
out these un-accurate temperature records themselves.
10.
The
"Password Reset"
button is inside the battery
compartment. Pressing the button once will reset the
password to
“88:88”
.
11.
The
“System Reset”
button is inside the battery
compartment. The user can reset the unit any time for re-
initialization of the unit or
in case the unit does not start up
after installation of the batteries. After this button is pressed,
the unit will go through the normal power up initialization
process, and all settings have to be re-entered. Only the old
alarm records (if there is any) can be retrieved after system
reset. The operator may use a paper clip or similar type of
object for accessing the system reset button.
Note: Old alarm records may be retrieved after hitting
System Reset button, but when alarm settings are re-
entered old records will be deleted.
