Settings Menus
A menu system is used to organize instrument settings by topic. This allows the safety specialist to first
choose the menu (topic) of interest, such as alarms, then review and optionally "edit" (adjust) each
available setting within that menu. Table 4.1 summarizes the settings that are available in each menu.

Settings summary
1.0
Maintenance
A primary purpose of the maintenance menu is to provide the safety specialist with
access to maintenance procedures (utilities). Menu options also include NFC and
Bluetooth settings, which are needed for an instrument that will use iAssign
accessories or will send instrument data to the iNet Now Sync App, respectively.
2.0
Start-up
Start-up settings allow the safety specialist to permit or prohibit all-user access—from
the start-up sequence—to some utilities and maintenance status information (e.g.,
number of days until calibration is due).
3.0
Operation
The operation menu allows the safety specialist to permit or prohibit—during
instrument operation—all-user access to utilities and maintenance status information.
Access is set separately for each item. For example, the option to clear the peak
readings may be permitted for all-user access, but access to calibration may be
prohibited.
From here, the specialist can also permit or prohibit the use of iAssign tags during
instrument operation.
4.0
Alarm
Alarm settings allow the safety specialist to set the values for each gas event that will
cause the instrument to alarm.
The specialist can also permit or prohibit instrument power off during alarms and
make other choices about alarm- and warning-related instrument behavior.
5.0
Sensor
Sensor settings allow the safety specialist to view basic information about the
installed sensors and control settings related to calibration and bump test utilities.
6.0
Admin
(Administration)
Admin settings allow the safety specialist to control important aspects about how the
instrument communicates with its operator. For example, a security code can be set
to help restrict all-user access to settings.
The safety specialist can also set the display-screen language, maintenance-related
warnings, and other items.
7.0
Wireless
Wireless settings allow the safety specialist to turn on or off LENS Wireless and to
choose settings for LENS' group-related warnings and data encryption.
The specialist can also set the instrument to sync-while-charging with iNet Now.
Examples for Working in Settings
Two examples are provided below to illustrate how to navigate in and adjust settings.
Each example includes a goal, a target setting that is to be changed; the navigation path that leads to the
target setting; and instruction to change the target setting.
Example 1 features a single-item setting—a setting that has a value of “on” or “off”.
Example 2 features a multi-item setting where the value for each of several items can be changed—one
item at a time.
