Getting Started
The TPQ-109 uses one CR2032 Lithium
battery that comes pre-installed. Turn the
device over and gently pull the battery
insulation sheet to remove it.
Press to turn the product on. Use
a paper clip to gently press the RESET
button on the back of the device. For
more information, please see “Resetting
your Device”. Warning! Pressing the
reset button with more than light pressure
may permanently disable your unit. In
addition, resetting the unit may erase
settings and information you may have
entered.
Replacing the Battery
The battery should be changed when the
screen contrast is too light even after
adjustment. Please have a small Phillips
screwdriver at hand before you follow the
steps below.
