which are incorrectly charged, such as on boats or with battery back-up systems such as those
used with alternative energy systems. The unit will alarm with 500 ppm H2 after between 10-
and 40-minutes exposure. This CO alarm is intended for residential use. It is not intended for
the use in industrial applications where Occupational Safety and Health Administration (OSHA)
requirements for carbon monoxide detectors must be met. This carbon monoxide alarming
device is designed to detect carbon monoxide gas from ANY source of combustion. It is NOT
designed to detect smoke, re, or any other gases.
WARNING: THIS CO ALARM IS DESIGNED TO PROTECT INDIVIDUALS FROM THE ACUTE EFFECTS
OF CARBON MONOXIDE EXPOSURE. IT WILL NOT FULLY SAFEGUARD INDIVIDUALS WITH SPECIFIC
MEDICAL CONDITIONS. IF IN DOUBT CONSULT A MEDICAL PRACTITIONER.
CAUTION: The alarm only indicates the presence of carbon monoxide gas at the sensor. Carbon
monoxide gas may be present in other areas. Individuals with medical problems should consid-
er using detection devices with lower COHb alarming capabilities.
Limitations of radio signals
The CO alarm is very reliable and is tested to high standards. However, due to its relatively low
transmitting power and limited radio range there are some limitations to be considered:
Receivers may be blocked by radio signals occurring on or near their operating frequencies,
regardless of the radio settings.
Radio transceiver equipment should be tested regularly, at least weekly. This is to determine,
whether there are sources of interference preventing communication, that the radio paths
have not been disrupted by moving furniture or renovations, and so generally protect
against these and other faults.
This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause interference to radio and television
reception. However, there is no guarantee that interference will not occur in a particular in-
stallation. If this device does cause interference, which can be veried by turning the device
on and o, the user is encouraged to eliminate it by one or more of the following measures:
Re-orientate or re-locate the unit.
Increase the distance between the CO alarm and the device being aected.
Consult the supplier or an experienced radio/television technician.
