The beep and the flash rate are directly proportional to
the RF field strength. Note that once the alarm starts, it
will latch at the minimum flash rate, continuing to warn
of an over-exposure even if the RF field that caused the
alarm is no longer present. In order to reset the alarm
function, the unit must be turned OFF and back ON using
the ON-OFF switch. For information concerning disabling
the latch function, refer to section 3.11. For information
concerning "Instantaneous" vs "Average" measurement
modes, refer to section 3.8.
3.5 Set-up Mode
The "Set-up" mode is used to set the alarm warning level
and to enable/disable the audible alarm. To enter this
mode, set the "ON-OFF" switch to ON. Then depress the
MODE switch after the initial three second period
referenced in section 3.4. The LCD display will indicate
"S.U.". At this point, the alarm warning level can be
changed (section 3.10) or the audible alarm indicator can
be enabled or disabled (section 3.7).
