To reset factory defaults, press the Option key and the Special key together when the Main
Window is displayed. The Reset Factory Defaults Window appears. Press the Enter key to
continue or the Cancel key to exit. Press and hold the Enter key to reset the factory defaults.
b. Auto Window
The Auto Window operates when the trigger level is set to Auto. The Auto Window determines
the length of time the BlastMate III continues to record after an event’s activity falls below the
trigger level. This ensures that an events delayed activity, particularly air blast, is recorded. For
example, if you plan to record an event at a long distance from the source, set the Auto Window
to a large value to compensate for the time required for the air blast to travel from the source to
the monitor’s microphone. If you set the value to a small value, the monitor may stop recording
after the seismic activity reaches the monitor but before the air blast reaches it. The Auto Window
values range from one to nine seconds.
To set the Auto Window, press the Option key and the Special key together when the Main
Window is displayed. Press the Cancel key to exit the Reset Factory Defaults Window and
display the Auto Window. Use the Up or Down Arrow key change the value. Press the Enter key
to save your setting.
c. Password
This feature activates a password control requiring an operator to enter a password before being
able to exit the monitor mode. The password prevents an unauthorized exit from monitor mode
while still allowing an operator to view event summaries. Password control can be enabled or
disabled. The default password is “3bm”. Passwords can be one to four alphanumeric characters
in length including spaces. Passwords can be enabled in all monitoring modes except the
advanced mode.
To display the password feature, press the Option key and the Special key together when the
main window is displayed. Press the Cancel key to exit the Reset Factory Defaults Window and
display the Password Window. Use the Up or Down Arrow key to display Enabled to turn the
password on or Disabled to turn the password off. If enabled, enter a password then press the
Enter key to save your setting. You have ten seconds to enter the password.
d. Auxiliary Trigger
The auxiliary trigger is an external triggering mechanism used to start monitor recording.
A variety of optional auxiliary triggers are available including the DS 20 Wire Trigger
(677A9601), and the BlastMate Trigger Cable (712A3901) used to connect several monitors
together for multiple point blast monitoring.
To use the auxiliary trigger, set the monitor in the single shot or continuous record mode. Set a
fixed record time. The auxiliary trigger does not operate in the auto record time setting. Press the
Option key and the Special key together when the Main Window is displayed. Press the Cancel
key to exit the Reset Factory Defaults Window and display the Auto Window. Press the Enter
key to display the Auxiliary Trigger Window. Use the Up or Down Arrow key to display
Enabled to turn the auxiliary trigger on or Disabled to turn the auxiliary trigger off. Press the
Enter key to save your setting.
e. Backlight On Time
This command sets the length of time the backlight remains on. If enabled, the backlight turns on
by pressing the
Back Light key. An adjustable timer, from 0 to 255 seconds, determines the
length of time the backlight remains on. To disable the backlight and not have it turn on, set the
timer delay to 0. This conserves battery power.
