Battery Replacement
The IRT has a low-battery indicator to let the user know when it is time to change the batteries. The right-hand decimal point in
the LCD display will illuminate (see illustration below). This will stay illuminated while the IRT is in use until the batteries are
changed or the battery charge is too low for the IRT to operate.
To Change The Batteries:
1. Remove slide cover on rear of unit.
2. Remove old batteries carefully.
3. Insert (2) new “AA” cell batteries.
4. Replace slide cover on unit.
5. Reset the configuration if a range other than the default setting is desired.
