6. Turning unit off:
a. To turn the unit off, press the standby button. The temperature, speed and time
displays will be blank, the standby indicator light will illuminate. The Incubating
Orbital 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

Opening the lid on the Incubating Orbital Shaker will cause the unit to pause shaking
and/or heating. Close the lid and the unit will resume shaking and/or heating at cur-
rent settings.
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 pre-
vented from rotating, or the unit is overloaded beyond its recommended weight capacity.
The shaker will automatically restart after a power interruption. Built-in memory main-
tains the last used temperature, speed and time settings during a power interruption.
LOAD SENSING FUNCTION
The Incubating Orbital Shaker is equipped with a load sensing function that can be
activated by the user. This function provides protection against improper positioning
of load and maximum load being exceeded. When activated, the unit will automatically
sense improper load conditions and slow to a safe running speed, then display that
speed followed by an E04 error message on the speed display. The unit will also beep
three (3) times every 60 seconds until the error is reset by pressing the speed on/off
button. To activate the load sensing function use the following steps:
1. Place the unit in standby mode.
2. Press and hold the speed on/off button and press the standby button. The unit will
beep two (2) times, confirming the function is enabled.
