MAX Mode Operation

While in MAX mode, the highest detected count rate (since the last reset) is
displayed. The word MAX will be displayed when in MAX mode.
Tapping  the  UNITS  button  will  switch  the  displayed  value  between  the
Primary and Secondary Units.
Tapping  the  ON/ACK  button  will  turn  the  “click”  audio  on/off.  When
Sigma Audio is enabled, tapping the ON/ACK button will toggle the Sigma

Audio beep on/off.
Under a non-alarm or alarm condition, a long press of the ON/ACK button

will reset the display. When Sigma Audio is enabled, the Sigma Audio alarm
level cannot be reset in Max Mode.
If  an  alarm  condition  is  present,  tapping  the  ON/ACK  button  once  will
acknowledge  and  turn  off  the  continuous  tone  alarm  audio.  (The  “click”

audio will remain as selected under non-alarm conditions.) Tapping the
ON/ACK button a second time will toggle the audio setting. Under an

alarm  condition,  the  ALARM  display  indicator  will  remain  on  until  the
display is reset. Alarms in MAX mode latch with the display.
If  other  operational  modes  are  available,  tapping  the  MODE  button  will
move to the next available operational mode.
