3-4-4 Latched Alarm
A feature of the unit's alarm system is that the beeps and
flashes are progressive. Once the alarm level has been
reached, the unit will indicate a single beep and flash
each 1.8 seconds with the "INST" annunciator displayed
or 3.6 seconds with the "AVG" annunciator displayed.
Should the unit detect a field that exceeds the preset
alarm level, the unit will start to beep and flash. The
beep and the flash rate are directly proportional to the RF
field strength. Note that once the alarms start, they latch
at the minimum flash rate, continuing to warn of an over
exposure situation even if the RF field that initially caused
the alarm is no longer present. In order to reset the alarm
function, it is necessary to turn the unit OFF and back ON
using the ON-OFF switch. If it is desired to disable the
latch function, follow the turn-on procedure described in
paragraph 3-4 except depress and hold the MODE switch
before placing the ON-OFF switch to the ON position.
3-4-5 Built-In Test Functions
The unit generates a beep and flash at turn on to verify
that the alarm indicators are functioning. At this time, all
segments of the LCD display are enabled to indicate that
the display is operating properly. Ten seconds after turn
on, the unit will generate a second beep and flash which
indicates that it is operational. A low battery condition is
indicated if the unit beeps and flashes two times after the
ten second period. To verify, check the LCD display for
a "BAT" indication. In addition, the battery condition is
tested automatically every minute. Should the battery
measure low, the "BAT" indicator will flash and the unit
will beep and flash once a minute. Refer to Section V for
battery replacement procedures.
