New Brunswick Scientific Operating Manual
 HEAT
Illuminates to indicate that the heater is on.
 TIME
Indicates that the timer is in operation. The shaker can be
programmed to run for a preset time from 0.1 to 99.9 hours.
The timer can be disengaged without stopping an ongoing run.
4.1.4 Function Indicators
Four function indicator lights are located to the right of the LED DISPLAY. They
indicate the current parameter(s) being displayed:
 C
Interior chamber temperature. Can be set from 4°C to 60°C,
when in
SET MODE, using the  (UP) or  (DOWN) KEY. It
indexes at 0.1°C increments unless the key is pressed for 4
seconds, after which it indexes more rapidly.

RPM
Revolutions per minute. When in SET MODE, use the  (UP) or
 (DOWN) KEY to change the speed. It indexes at 1 RPM
increments unless the key is pressed for 4 seconds, after which
it indexes more rapidly.
 HRS
Time remaining in a timed run. Can be set from 0.1 to 99.9
hours, in 0.1 increments or, if the  (UP) or  (DOWN) KEY is
pressed for 4 seconds, after which it indexes more rapidly.
The countdown begins when the START/STOP key is pressed.
If the START/STOP key is pressed again, the shaking stops (but
temperature is maintained) and the timer pauses until the
START/STOP key is pressed again.
When a timed run ends, the
HRS indicator will blink. Press the
SELECT key and change to another function to turn off this
indicator.

MUTE
This feature is activated by the SELECT key. When activated,
the audible alarm is muted, and remains so until it is reactivated
with the
SELECT key. If MUTE is activated when the shaker is
turned off using the
ON/OFF switch, it will remain engaged
when the machine is powered up again. To activate (or
deactivate) the
MUTE function, press the SELECT key until the
MUTE indicator illuminates (or goes out), then press
START/STOP key.
