The Audible Indicator
The SM45 has an onboard audible indicator.
The audible indicator informs you about pressing invalid keys and active alarms as follows:
• One beep every 2 seconds - indicates that a non-urgent alarm is active
• A continuous sound - indicates that an urgent alarm is active
An urgent alarm always overrides a non-urgent alarm.
► To disable the audible indicator (when an alarm is active)
• Press any key
At the next active alarm, the audible indicator is automatically enabled again.
Display Time-out
The SM45 has a display time-out function – that is, if no keys are pressed for a
predetermined time interval, the SM45 reverts back to the default display (total rectifier
current).
The predetermined time interval varies (according to the display mode you are in) as
follows:
• Edit Mode – no time-out
• All other display modes – 2 minutes
