SETTING HIGH AND LOW TEMPERATURE ALARMS
Temperature alarms can only be set for the sensor in the external probe. You cannot set alarms with
the display unit mounted on a wall or frame because setting alarm levels requires access to the °C /°F
button on the back of the unit. Before proceeding, detach the unit by pulling it off the metal frame or
separating the Velcro mounting strips.
1. To set either or both alarms, begin by pressing the button and holding it for 3+ seconds.
This will cause the display to begin flashing a value, along with the non-flashing terms HIGH
and EXT. The term AL will also appear (not flashing), in the lower left corner. You now have
1 minute to set the high temperature alarm limit at any level within the remote probe’s range
of -58° to 158°F (-50° to 70°C) by following Step 2. If you do not wish to set the high
temperature alarm, skip ahead to Step 3 below.
2. To set the high temperature alarm limit, hold the unit in one hand in front of your face.
With your other hand, reach behind the unit and begin pressing the °C /°F button. Each press
of the button increases the alarm temperature level (as shown on the display) by 1.8° with
the display in °F mode and by 1° with the display in °C mode. To speed up the process by
increasing the temperature in multiple steps, press and hold the °C /°F button.
When the desired high temperature alarm level is displayed, pres
s the button
to store the setting. The beeper will sound once and the display will begin to flash a value,
along with the terms LOW and EXT. You now have 1 minute to set the low temperature alarm
level at any value within the remote probe’s range of -58° to 158°F (-50° to 70°C). If you do
not wish to set the low temperature alarm, press the button again and skip ahead to
Step 4 on next page.
