3. Pull the IR cell straight out by grasping both edges of the label and pulling
evenly.
4. Remove the replacement IR cell from the protective package.
5. Carefully align the male leads and air tubes on the IR cell with the connectors
mounted on the circuit board. Insert the leads into the sockets and push the IR
cell straight down.
NOTE: Ensure the lead connectors on the IR cell ends are not bent and the cell
is seated tightly.
Removing/Replacing the Power Stick
The D-TEK CO2 uses a preassembled power stick/battery.
Remove the battery compartment door on the back of the D-TEK CO2 by pressing
on both release buttons on the grip and pulling the door straight out. The power
stick is connected to the PCB board via a miniature electrical connector.
Disengage the connector and slide the power stick out of the D-TEK CO2.
To install a fresh power stick, slide the new stick into the D-TEK CO2 and push the
miniature connector on the power stick into the mating half on the PCB board.
Once the power stick is in place, close the battery compartment by aligning the
two tabs and sliding the door straight in until it latches. Ensure the wire leads on
the power stick are not pinched in the door. Allow 10 hours to fully charge the new
power stick.
NOTE: If unit does not power up after the power stick is replaced, verify that the
key connector on the power stick is mated properly to the connector on
the circuit board. Reverse the connection if necessary and power up
again. If the Hi/Lo indicators flash in a rapid, alternating manner when the
AC adapter is connected, the power stick is installed backwards.
