Alarm conditions: TWA alarm, STEL alarm, low alarm, high alarm, multi-gas alarm, over limit (OL) alarm, low battery alarm, confidence beep, automatic deactivation alarm, and pump alarm

Audible alarm: 95 dB+ at 30 cm variable pulsed beeper with full battery charge

Visual alarm: Red light-emitting diodes (LEDs)

Display: Alphanumeric liquid crystal display (LCD)

Backlight: Activates upon startup and when the pushbutton is pressed; deactivates after 10 seconds. Also activates during an alarm condition and remains lit until alarm ceases

Self-test: Initiated at activation and tests continuously

Calibration: Automatic zero and automatic span

User field options: Startup message, lockout on self-test error, safe mode, confidence beep, latching alarms, force calibration, cal IR lock, force bump, location logging, force block test, set datalog interval, set confidence interval, language selection

Sensor options: Sensor enable/disable, set span calibration values, set calibration interval, set bump interval, set alarm setpoints, set STEL interval, set TWA period, auto zero at startup enable/disable, 5% over span, low alarm acknowledge, oxygen measurement, and combustible gas measurement

Battery operating time: One rechargeable lithium polymer: 13 hours (typical)

Year of manufacture: The detector's year of manufacture is determined from the serial number. The second and third number after the second letter determines the year of manufacture.

E.g., MA 110-000001 = 2010 year of manufacture

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules and ICES-003 Canadian EMI requirements. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
