When inserting the battery, make sure that thepolarities (+ and -) are correctly positioned.
If the battery polarity is reversed, the detector
cannot be turned on and a continuous vibration may
occur depending on the type of battery. Remove
the battery promptly and insert it again with thecorrect polarity.

7 ．Speciﬁcations

The remaining battery level indication decreases gradually as the battery
level decreases as shown below:
Before remaining battery level is exhausted, the last indication will blink
with an intermittent alarm sound in -second intervals. (Preliminary alarm)
When the remaining battery level is exhausted, [Err.b] is displayed, accom panied by a continuous alarm sound. The product will no longer operate.
(Final alarm)
Stop the alarm sound by turning the power OFF.

→Execute daily check in clean air before use.
① Operation
Check alarm sound, alarm lamp,vibration and LCD work properly when
the detector is turned on. If not ,request repairs.
② Alarm function
Check the alarm indications such as alarm sound, alarm lamp and vibrationby having the detector draw O at a level that is slightly below
the alarm set value.
In the event of an abnormality in the way the O concentration
readings change, such as the alarm lamp does not ﬂicker or the buzzer does
not sound, request repairs.
③ Remaining battery level
Check the remaining battery level of the gas detector.
If the remaining battery level is low, replace new battery.

４．Replacing Battery→（ ） Daily Check④ Gas sensor opening
Check that the gas sensor opening is not blocked and the ﬁlter element isclean and dry. Replace the element if dirty or wet.
(See “Replacement Parts” on page 5)This product is a precision instrument. Please perform the periodical checks andinspections below to maintain the detectorʼs performance and ensure safety.
In the event of a failure to follow the safety precautions (page 2), such as impact shockfrom dropping or exposure to water, or use in conditions outside the speciﬁcations(page 13), such as usage in temperature/humidity exceeding the speciﬁed range,
please contact New Cosmos or your New Cosmos representative for inspection.
A comprehensive description of the current situation would be appreciated when you
contact us.

The cycle of the alarm sound and the alarm blinks become
faster for the second stage than that for the ﬁrst.
The backlight of the LCD display turns on during an alarm.

Press the [Power (PEAK)] switch and [Air Adjustment] switch
at the same time. The display will blink only while the switches
are held down at the same time, indicating the peak value fromthe time of power on to the present. The subsidiary display
indicates the elapsed time since the peak value was observed.

If the operation switches or displays do not operate properly other thanwhen alarms are activated as above, remove and reinsert the battery into
the product. Turn the power supply on to check performance. If it cannot
be restored with this procedure, request repairs.

６．Maintenance（Alarmsound）⑤ Peak value memory function [Memorize and check thepeak value between power ON and OFF.]

Incorrect air adjustment or sensor malfunction.
Make an air adjustment again in clean air.
Request repairs if the alarm does not disappear
after several adjustments.
Readout error. Remove and reinsert the battery.
Turn on the power supply to check performance.
If it cannot be restored with this procedure,request repairs.

( nd stage alarm)（Alarmsound）

The above-recommended cycle is only an estimatebased on normal use and proper maintenance without
exposure to high concentration gas or gas poisoning;
therefore, no guarantee is provided.

No remaining battery level. Replace the battery. (See
「Replacing Batteries」on page)Be sure to execute the air adjustment in clean air.
Accurate O concentration reading cannot beobtained when the power is turned on in acontaminated air.
Execute the air adjustment at least once a day. In
addition, when the work environment (temperatureor humidity) changes, make the air adjustment
because the. % point may drift.

● First and Second stage alarm
If the O concentration falls below the ﬁrst or second stage alarm concentration
setting value, the O concentration display, alarm display and alarm lamp
blink, accompanied by alarm sound and vibration.

The recommended replacement cycle for sensors isone year. Replace the sensor with a new one annually
to ensure correct detection.
