2.6 Backlight the Display

When used in dark locations, the display of the Portable Digital Thermometer can be illuminated by pressing the LIGHT/OC button. The backlight will turn off automatically after approximately 30 seconds, or may be turned off manually by pressing the LIGHT/OC button a second time.

2.7 Disable the Auto-Shutoff

The Portable Digital Thermometer will normally turn itself off after 15 minutes. Pressing any of the buttons will delay the automatic shutoff for another 15 minutes. The technician can disable this auto-off feature by pressing the LIGHT/OC button three times within 5 seconds. The small º F (or º C if in Celsius scale) at the right side of the display will blink on and off to indicate that the unit is in “ON CONTINUOUS” mode and will not turn itself off. This function is useful for MIN/MAX data collection over extended time periods.

NOTE

You may wish to use the optional AC power adapter when in “ON CONTINUOUS” mode to prevent possible data loss due to battery failure.

2.8 Battery Replacement

When the battery in the Portable Digital Thermometer needs to be replaced, the display will show “LO P”. Replace the battery with a 9-volt alkaline or equivalent NEDA type 1604A battery.

CAUTION

This unit is not waterproof. Do not immerse for cleaning. If unit becomes wet inside because of cleaning, rain or condensation, unstable readings may occur. NOT INTENDED FOR HUMAN MEDICAL USE.
