1. SAFETY AND USAGE INFORMATION
Improper use or usage in an inappropriate environment may degrade the instruments performance.
Read the safety information below before using/operating this device.
Do not use a damaged device. Check for cracked or missing parts before use.
Before use it is advised that a “Bump Test” be performed. See section 6.3 for more information.
If the reading is out of range then the device should be calibrated. See section 6.7 and 6.8.
Periodic “Bump Tests” will allow for testing of the sensor response, visual, audible and vibrate
functions.
Do not use accessories that are not designed to be used with the EX660.
Only use the charger provided with the EX660. Do not charge the device in hazardous
environments.
Do not expose the device to high gas concentrations for an extended period. Doing so can harm
sensor performance and possibly damage them.
Do not use the device in environments that contain lead compounds, sulfate compounds, organic
phosphorus compounds, or silicon. These compounds can damage the sensor cells.
Avoid exposure to environments that contain H2S, Hydrocarbons or acidic gases for an extended
period. If the device has been used in these environments preform a “Bump Test” before its next
use. See section 6.3.
Avoid exposure to environments with the potential for electric shock, strong magnetic fields or
extreme continuous mechanical vibration.
Do not discard the lithium battery in the trash. Follow local regulatory requirements for disposal
of the battery.
Do no preform any unauthorized maintenance of the device.
Avoid dropping the device from heights and extreme impacts.
For usage information not included in this manual contact IMR.

6. OPERATION INSTRUCTIONS
6.1.POWER ON
When the device is powered off, hold
for more than 3s and it will power on. The
screen will display as below.
After powering on, the device will proceed to
self-test and the screen will display as below.
The device will then test the buzzer, alarm
lights and vibrator. After the self-test it will
enter into normal mode and the screen will
display as below.
Note:
If a self-test fails the relevant information
will be displayed. See section 11 for more
information.
If self-test succeeds the device enters into
a warm-up period of 3-30s which depends
on the sensor type.
6.2.POWER OFF
In normal mode hold for 3 seconds and
the screen will show “Shutting down…” and
the buzzer will give beep twice. Then device is
then powered off.
6.3.BUMP TEST
It is suggested that before each use to perform
a Bump Test to verify the device is working
normally.
Test method:
With the device powered on put it into a high
concentration gas environment. This area
should be higher than the preset high alarm
point. If all of the devices alarm functions
react then the device can be used normally.
Note:
If any reading is the expected error range
then see section 6.7 and 5.8 to recalibrate
the device.
If the device does not respond as expected
or displays errors then contact IMR.
