  Most UEi handheld instruments feature a battery compartment on the back secured by captive screws. Refer to your specific device model's manual for battery type (commonly AA, AAA, or 9V) and replacement instructions.

  If your UEi CO detector indicates dangerous levels of Carbon Monoxide, evacuate the area immediately to fresh air and contact emergency services. Do not re-enter until the area has been declared safe by professionals.
