11. Product Care

To insure you receive the maximum benefit from using this product, observe these guidelines:

•

Repair - Do not attempt to repair the product or modify the circuitry by yourself. Please

contact CO2Meter directly if the product needs servicing, including the replacement or

calibration of sensor See section 15 for technical support contact information.

•

Cleaning - Disconnect the power before cleaning. Use a damp cloth. Do not use liquid

cleaning agents such as benzene, thinner or aerosols, as these will damage the device.

•

Maintenance – We recommend testing the communication between the SEU and RDU

under 'DIAG" function. If these five LEDs blink and the buzzer of SEU and RDU sound

simultaneously, it indicates that SEU and RDU work normally.

12. Safety Notes

the protection provided by the equipment may be impaired. These warnings provide important

safety information and should be observed at all times.

1. Please handle the device carefully; do not subject the product to impact or shock.

Otherwise, this may cause the accuracy drift.

2. Do not place the unit near a heat source. Heat can cause distortion of the unit, which may

result in an explosion or fire.

3. Do not touch the exposed electronic circuitry of the device under any circumstances, as

there is the dangerous of electric shocks.

4. Please take care of cable connection between SEU and RDU. Make sure the cable from

SEU is connected into the INPUT port of RDU.
