SAFETY INFORMATION

Improper use or use in an unsuitable environment may degrade the instrument’s performance. Please read the

below safety information carefully before using and operating this device.

Do not use a damaged or defective device. Before using the device check for any cracks or spare parts that

are missing. If an issue is found contact IMR immediately.

It's suggested to carry out a "Bump Test" before each use. Section 5.3 of this manual contains the procedure.

If the device is reading outside of normal range, please calibrate the device by following Section 5.7 and 5.8

of this manual.

A Bump Test will check the responsiveness of the sensors. Verify that the visual, audible and vibration

alarm signals are nominal.

Only accessories that are designed for the IMR EX660 or authorized by IMR are permitted.

Only the charger that is designed for the IMR EX660 is authorized to be used. It's exceedingly hazardous to

charge the device in a dangerous environment.

Do not expose the device to the exceedingly high concentrations of detectible gases for an extended period

of time. It will harm the performance of and even damage the device.

If exposed to an environment consisting of leaded compounds, sulfide compounds, organic phosphorus

compounds or silicon, the gas sensors will be damaged. Do not use the device in the above environment.

Do not expose the device to environments which consist of H2S, Hydrocarbon gas or highly corrosive gas

for an extended period of time. This will reduce the responsiveness of the gas sensors and reduce their

sensitivity. If the device is to be used in the above environment, please follow Section 5.3 to perform a

Bump Test before using it.

Do not expose the device to environments that have electric shock, strong magnetic fields or hard

continuous mechanic impacts.

The device uses a lithium battery. Do not discard a defective battery in the trash. A defective battery should

be disposed of in accordance with local governmental and regulatory standards.

Unauthorized disassembling, modification or repair the device without permission is not covered by IMR.

Avoid dropping the device from highs and avoid severe impacts.

For any other usage beyond this manual, please contact IMR.

Note:

If the self-test fails relevant information will be displayed. For details refer to Section 10

Troubleshooting.

If the self-test succeeds the device then enters into a warm-up period of 3-30s duration depends on the

type of sensors equipped.

5.2 Power Off

In normal detection mode, hold for 3 seconds and the screen will show “Shutting down…” Meanwhile

the buzzer will give out an intermittent beep twice. Then the device will power off.

5.3 Bump Test

Every day before using the device, it is suggested to carry out a Bump test, so as to check if the device is

working normally.

Test method:

When the device is powered on put it into an environment with a high level of gas. The test gas should be

higher than a preset high alarm point on the device. If all of the device’s functions are nominal then the device

can be used in the field.

Note:

If any readings on the screen are beyond the prescribed display error range, please follow Clause 5.7 and

5.8 of this manual to re-calibrate it.

If the device does not respond or is showing errors please contact IMR for repair.
