Battery Replacement -
The unit is shipped with one CR ½ AA size 3V Lithium battery, which is pre-installed.
To change the battery, remove the battery cover by pushing inward and down. Install the
battery in either of the two slots. The unit runs on a single battery, and the second slot is
provided to allow for installing a new battery before removing the old one, retaining count
total and program data. The unit can also be run on two batteries to extend the battery life
to 10 years.
Once the battery is in place the unit will go into a self test mode, and all the segments on
the LCD display will be illuminated. The self test mode is exited by depressing the Next key,
which will then display the model number (6). Depress the Next key again to ready the unit
for operation.
