6.1 Calibration

The CD-6B uses an optional automated background calibration "Abc" to set the clean air level. The CD-6B will
maintain accuracy if it is exposed to the "clean air reference value" (this reference value is the lowest concentration
to which the sensor is exposed) at least once per week.
N OTE: This applies when used in the typical indoor ambient air with weekly unoccupied periods.

If automated background calibration "Abc" is disabled, manual calibration at regular intervals will be required to
reliably maintain accuracy (See section 7 Testing). The device can be set to issue calibration reminders using the
Calibration Period "CAL" setting (see section 4.8.16).

6.2 Sensor Life Reset

The Sensor Life can be extended only by 1 year, so the sensor life reset option is not available once the extended 1
year is over.
After resetting the sensor life, the unit will still indicate a "t 80" error and will need to be calibrated before it can be
used for the extended 1-year life.
To reset the sensor life,
1. Remove the Philips screw on the front of the CD-6B. Pull the front cover of the unit off.
2. From normal mode, press NEXT four times. The display will show "SEn" or Sensor Mode.
3. Press ENTER. The display will show "rSt" or Reset Sensor Mode.
4. Press ENTER to see the sensor reset status.
5. If the sensor life has already been reset, "don" will be displayed. If it has not been reset, "no" will be
displayed. Press NEXT to change it to "YES" (flashing).
6. Press ENTER to confirm the change (solid) and press ENTER again to return to "rSt" in the "SEn" menu.
7. Press NEXT until "End" is displayed then press ENTER to get back to normal operation. The sensor life will be
reset for 1 year.

6.3 Cleaning

Cleaning of the external surfaces is best carried out using a damp cloth with a mild detergent or soap. Use a vacuum
cleaner with a soft brush to remove dust or contamination under the cover. Do not blow out the sensor with
compressed air.
CAUTION
Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such materials may permanently
scratch the surfaces and damage the display window, labels, sensor or instrument housing. High voltage terminals
(100-240VAC) are located within this detector, presenting a hazard to service technicians. Only qualified technicians
should open the detector case and service the internal circuits. Ensure power is removed from the detector prior to
cleaning the unit.
