OPERATING INSTRUCTIONS CONT'D
5. Turning unit off:
a. To turn the unit off, press the standby button. The speed and time displays will
be blank, the standby indicator light will illuminate. The Extreme Shaker should
be kept in standby mode when not in use. To completely cut off power to the
unit, disconnect the power cord from the unit or unplug from the wall outlet.

OPERATING TIPS

Centering your sample and even weight distribution on the tray helps with balance
and stability. As a safety feature, a built-in program will shut power off to the motor if
the tray is prevented from rotating, or the unit is overloaded beyond its recommended
weight capacity. The shaker will automatically restart after a power interruption. Built-in
memory maintains the last used speed and time settings during a power interruption.
BEEPER PREFERENCE
To silence beeper operation (except for error codes), with the unit in standby mode,
press and hold the time on/off button and press the standby button. To restore normal
beeper operation, remove AC power to unit for ten (10) seconds and then restore.

CALIBRATION PROCEDURE

This procedure is used to self calibrate the Extreme Shaker. The tray should be free
of any samples, vessels, and accessories prior to calibrating.
1. Turn unit on. Speed and time displays will be illuminated.
2. Press and hold the standby button and momentarily press the speed on/off button.
The speed display should read "CAL".
3. The unit will run for approximately one (1) minute and automatically calibrate.
