beeps once.
THE WARM-UP SEQUENCE AUTOMATICALLY RUNS
a. All sections of the monitor’s screen turn on, the backlight turns on,
and the monitor beeps and vibrates.
b. The monitor cycles through calibration status, date/time, battery
voltage, target gas, and alarm setpoint screens.
c. After the warm-up sequence is complete, the monitor beeps 2 times
and the screen displays CO at the top left, the battery icon at the top
right, and a ppm reading at the lower right. The monitor now is in
Measuring Mode.
NOTE: If the monitor indicates a low battery (only the last bar in the
battery icon shows) or if it sounds the dead-battery alarm, replace the
battery. Refer to the operations manual for instructions.

lower-right of the screen.
ASSEMBLING THE CALIBRATION CONNECTOR
ASSEMBLY (See FIGURES 1 and 2.)
1. Required Material:
a. 0.5 LPM fixed-flow calibration connector with slide valve
b. 3/16” OD calibration tubing
c. Calibration cup

connector with slide valve.
3. Slide the other end of the 3/16” tubing onto the inlet barb of the
calibration cup.
NOTE: The calibration cup has directional flow. The flow-direction arrow
shows the direction of air flow. The tubing connects to the barb on the
backend of the flow arrow. The outlet barb (on the front end of the flow
arrow) remains open.

ADJUSTMENT.)
3. Confirm that the calibration connector’s slide valve is CLOSED
by sliding it DOWN, toward the test-gas cylinder connection.
(See FIGURE 1.)
4. Screw the calibration connector onto the test gas cylinder.
5. Turn OFF the monitor by pressing and holding the POWER/MODE button.
The monitor turns off after 4 beeps. Release the POWER/MODE button
after the monitor’s screen goes blank.
6. Press and hold the AIR and POWER/MODE buttons. Release the buttons
after the monitor beeps 1 time. The monitor beeps again and BUMP
displays in the bottom left of the screen.
7. Press the AIR button once (1 beep), and GAS CAL displays at the bottom
of the screen.

Quick-Reference Guide for Common Functions
NOTE: This quick-reference guide is a supplement to the operations manual, which should be read in full.

8. Press the POWER/MODE button once (1 beep), and AIR displays in the
bottom left of the screen.
9. Press the AIR button once (1 beep), and A-CAL displays in the bottom
left of the screen. (NOTE: If E-CAL displays instead of A-CAL, the
monitor is in the incorrect mode. See the operations manual.)

6. Press the POWER/MODE button once (1 beep), and the calibration value
(25) displays near the lower-right corner of the screen.
7. Snap the calibration cup to the front of the monitor over the sensor
retainer. (The sensor retainer is located to the right of the screen.) The
arrow embedded in the calibration cup must point up and to the left.
(See FIGURE 2.)
8. Open the connector’s slide valve by sliding it UP, to the OPEN position.
(See FIGURE 1.)
9. Press the POWER/MODE button once (1 beep). The gas reading flashes,
and the monitor counts down from 30 seconds in the lower-right corner.
10. After the countdown reaches zero, the bump test is complete.
11. If the bump test fails, a calibration is immediately and automatically
started. Continue to apply the calibration gas. AUTO CAL will appear at
the bottom of the screen, and a countdown will appear in the bottom
right. Refer to the operations manual for more information about a failed
test.
12. If the bump test passes, P (passed) displays on the left of the screen.
Proceed to Step 13.
13. Close the connector slide valve, remove the calibration cup from the
monitor, and unscrew the calibration connector from the test gas cylinder.
14. Press the POWER/MODE button once (1 beep), and END displays in the
bottom left of the screen. The monitor will then beep, and BUMP now
displays in the bottom left of the screen.
15. Press the AIR button 14 times (14 beeps), and START displays in the
