5.1 Replacing the Batteries
When you change the batteries, all of the set parameters
(i.e. emissivity, high alarm, low alarm, Target Ambient
Temperature) will be reset to the default values. For your
convenience, you may want to write down all of the set
parameters BEFORE replacing the batteries.
The thermometer is powered by 4 standard AA size lithium
batteries. To replace the batteries:
1. Invert the thermometer and open the cover of the battery
compartment.
2. Remove the old batteries.
3. Install 4 fresh AA size (lithium or alkaline) batteries as shown in
Figure 2-1.
4. Close the battery compartment cover.
When the battery power is so low that accurate measurements
are no longer possible, the thermometer shuts down and you
must replace the batteries immediately.
You will see and hear the following:
• The icon flashes
• The thermometer beeps intermittently
• The thermometer flashes “ “ in the main display.
Safety Warning
Do not open batteries, dispose of in fire, heat above
100°C (212°F), expose contents to water, recharge, put in
backwards, mix with used or other battery types – may
explode or leak and cause personal injury.
