Buzzer: Appears by flashing in red whenever the alarm status occurs.  The buzzer will 
disappear after the user acknowledges the alarm, or the process becomes normal. 
 
Evnt: The percentage of memory space left for events/alarms.  For example, evnt 84% means 
84% space left for events/alarms.  Refer to Event/Alarm Limit in 4.4 Instrument.  Various 
numbers of events/alarms can be set. The icon flashes red when memory space is down to 25 %.  
The icon returns to normal green after pressing the soft key, either Dump or Clear. 
 
mem: The percentage of memory space left for measured data. The icon starts flashing red 
when the memory space is down to 25%.  The icon becomes normal green after press soft key 
either Dump or Clear.  If the internal memory goes down to 10 %, the earliest measured data 
and events will be saved to CF card in small batch automatically. If there is no CF card 
inserted, then the earliest measured data and events will be overwritten and replaced by the 
latest measured data and events. 
 
CF:  The icon shows the status of Compact Flash card.  If the CF card is not inserted, the icon 
shows a red-cross sign.  If it is properly inserted, then the icon displays normal green and 
indicates the percentage of the memory space left on the CF card.  The icon starts flashing in 
red when the memory space goes down to 25%.  The icon becomes normal green again after 
downloading data and events from the CF card to PC.  If the CF card is inserted in the 
recorder and its memory is full, then the memory of CF card remains unchanged and the 
earliest measured data and events on the recorder  will be overwritten and replaced by the 
latest measured data and events.
