User Controls and Display

WARNING THIS IS A BETA RELEASE MANUAL NOT FOR 2.106 FIRMWARE

The 2B unit has five user controls. Each control allows the user to adjust a particular aspect of the output. It is the operation of the controls in combination that will allow the user to provide an effective electro-stimulation session.

2b controls

The controls are (from left to right)

Channel A Level Control

The Select Button

The Adjust Control

Channel B Level Control

There is also a power slide switch (on the bottom side of the unit) and an LCD contrast control (accessed from the rear of the unit.)

Channel Level Controls

The channel level controls adjust the absolute level of the output of the relevant channel. Each Channel control value is displayed on the LCD screen, with values from OFF (0) to MAX (100%). OFF is zero output, MAX is full output. The output levels automatically drop to OFF when selecting a mode, and will always start off at OFF (0%) when selecting a new mode.

Select Button

The select button is used in conjunction with the Adjust control, to change and adjust the settings in all the various modes, including changing and selecting the modes themselves. The Select Button responds to a light press, there is no need to press too hard. Pressing and holding the Select Button while rotating the Adjust Control allows further adjustments of the Feel in many modes.

Adjust Control

The adjust control is used in conjunction with the select button, to change and adjust the settings in all the various modes, including changing the modes themselves.

Depending on the mode, the 'C' and 'D' values can be adjusted using the Adjustment Control. Turning the Adjustment Control either clockwise or anticlockwise will change the 'C' adjustment value up or down, while pressing and holding the select button and turning the Adjustment Control which change the value of the 'D' setting. Not all modes use both the C and D values.

Displays

The 2B has 3 display elements, the bright backlight LCD display, giving the user details of all of the functions of the 2B, from control settings to helpful messages.

The two blue LEDs on the right hand side of the unit illuminate in proportion to the intensity of the relevant output. The LEDs might appear to glow slightly when the unit is turned on and there is no output - this is due to the internal reflection of the backlight and is not a fault.
