5. Consumable Replacement
Battery Replacement BP-4000llAL
The user can estimate the timing of battery replacement by checking the battery level
indicator on the LCD. When the battery is drained, “E-B” will be displayed on the LCD
and the unit will beep, and the detector will not detect gases any longer. The LCD will
then turn off when the battery is completely drained.
1) Press and hold the [ POWER] button for 3 seconds to turn off the power.
2) Rotate the battery cover counterclockwise 45 degrees
with a Phillips screwdriver (point size: 2) to unlock.
Continue turning until the cover lifts up. Turn it once or
twice to free the cover.
Battery cover
MENU
Use a screwdriver with point size 2 (see
page 33 for the shape). If the
screwdriver is too small, it may damage
or deform the battery cover.
Slowly turn the screwdriver. The battery
cover will be damaged or deformed if too
much force is used.
NOTE

[Battery Level] HIGH - - - - - - - - - - - - - - LOW Need to replace
Be sure to use a new battery for replacement.
When used at low temperature, the battery life will be shorter than when
used at room temperature due to battery’s characteristics. If the battery
level is low, it is recommended to replace the battery before it becomes
empty.
NOTE
Replace the battery only in non-hazardous locations.
Make sure to use a Panasonic (or Duracell or Energizer or
Varta) alkaline battery (LR03/AAA). We cannot guarantee the
intrinsically safe performance if an unspecified battery is used.
Be sure to remove contaminates from the O-ring of the battery
cover and the joint surface between the detector and the
battery cover. Contaminates such as dirt may cause water
ingress into the detector.
Remove water and dust from the unit before opening any part
of the gas detector. Entry of water or dust inside the detector
may cause a failure.
If the O-ring attached to the battery cover is damaged, replace
the whole battery cover with a new one. Failure to do so may
cause water ingress into the detector.

4. Error Messages
If an abnormality occurs in the detector, the corresponding error message will be
displayed on the LCD, the unit will beep, the alarm lights will flash, and the vibrator will
intermittently vibrate. Note that the audio alarm for a sensor error will be activated only
when all of the mounted sensors fail.
To silence the audio alarm, press the [ AIR ADJ.] button. The flashing lights and
vibration will be stopped when the power is turned off.
The table below lists major error messages. If an error occurs, check the cause of the
error and take necessary actions. When no error message is displayed but button or
display does not function, remove the battery, reinstall it, and turn on the unit. If the unit
does not reset to normal, contact New Cosmos or your New Cosmos representative for
repair.
