TURNING ON THE CMS-4 MONITOR-ALARM
1. Press and hold the POWER/MODE button until the monitor
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.

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
2. Slide one end of the 3/16" tubing onto the barbed end of the calibration
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.
CALIBRATING THE CMS-4 MONITOR-ALARM
1. Required Material:
a. 25 ppm CO test-gas cylinder.
b. Calibration connector assembly. (See ASSEMBLING THE CALIBRATION
CONNECTOR ASSEMBLY.)
2. Perform a fresh-air adjustment. (See PERFORMING A FRESH-AIR
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.
