IMPORTANT SAFETY INFORMATION

Read This Page Before Using

CAUTION

The ET312, like most electrostimulation devices, can cause serious
harm if misused. Always make all connec- tions with the power OFF. Current passed

through the heart, neck or head can be fatal. If you have any doubt about the safe use of
electrostimulation, consult a physician and ErosTek before using.

Use the ET312 at your own risk understanding the ET312 may be harmful if
misused. Given the nature of electrostimulation, ErosTek cannot be liable for any damage
or harm of any kind caused by or related to ErosTek products. Treat the ET312 like a sharp
knife or power tool. It must be used properly or injury may result.

IMPORTANT! E-stim devices are NOT for use by or on anyone with implanted electronic

devices – pacemakers, debrillators, drug pumps, etc. – heart problems, heart disease,

epilepsy, brain disorders, nervous system disorders, a history of strokes or seizures,
serious skin problems or similar medical conditions. Not for use by pregnant women,
women who might be pregnant, or anyone under the age of 18. Current passed through the
heart, neck or head can be fatal. Keep away from children.

The ET312 is intended for use only by healthy, consenting adults familiar
with safe electrostimulation and proper operation of the ET312. If excessive

soreness, skin irritation or other conditions develop, discontinue use. Use care in operating
the device until you’re familiar with it. Sudden stimulation at high levels may cause muscle
injuries, a person to fall, or other harm.

Use the ET312 only with attachments and accessories designed for safe
electrostimulation. Do not attach it to body piercings or similarly small electrodes. Do

not connect the channels together except as shown in section A4 of this Guide. Do not
attempt to open, repair or modify the ET312. Use only the correct AC adapter.

Make sure you connect any external equipment to the proper jacks.

Electro-stimulation uses electrical signals that can damage sensitive audio and computer
equipment. If connections are made to the wrong jacks, the connected equipment may be
damaged. Always make all connections with the power turned off.

Do not use the ET312 in conjunction with “violet wand” type devices. The
extremely high voltages produced by these units can damage the ET -312 and many other
electronic devices.

1: GETTING STARTED

The ET312 is the most advanced unit of its kind and offers many unique sensations.
Before you go any further, please make sure you have read the Important Safety
Information on page 3 . If you’re new to electrostimulation or just like to keep things
simple, you need only read sections 2 - 4 to get started while sections 5 - 13 offer more
details and let you get the most from your ET312.

The ET312 is like a fully automatic camera which makes things simple by making most of
the adjustments for you. And, like a professional camera, it also offers optional features for
the more experienced user. The Advanced Topics section is for more advanced users.
Regardless of the features used, the ET312 offers superior performance when compared to
any erotic electrostim product.

2: INTRODUCTION TO E-STIM

Erotic electrostimulation (e-stim) is yet another example of how technology is improving
our lives. Partners have discovered it’s the perfect enhancement to spice up their love life.

Individuals nd it takes masturbation to a whole new level with some even experiencing

“hands free” orgasms. Still others use it for erotic BDSM play where it creates high-intensity
sensations without causing the lingering discomfort and possible harm you get with other
techniques.

Electrostimulation, in one form or another, has been around for decades. It’s commonly
used, for example, in physical therapy and pain management by the medical community.
The ET312 produces a similar output to medical TENS (Transcutaneous Electrical Nerve
Stimulation) and EMS (Electro Muscle Stimulation) units.

The ET312 works by using a special waveform made up of high frequency pulses. This

current stimulates the nerves and muscles in unique ways and ows between two pairs of

contacts (often called electrodes) connected to each channel of the ET312.

Some erotic e-stim accessories have a pair of contacts built in. We call these “bipolar”
electrodes and they usually have an attached leadwire that plugs directly into the ET312
or they have two (2) connections points. Other electrodes only have a single connection.
These are called “monopolar” electrodes. These must be used in pairs. The leads supplied

with the ET312 work with many popular erotic accessories and can be adapted to t any

accessory using the appropriate wiring adapter.

3: BASIC OPERATION

Using the ET312 is very simple. Just follow these easy steps:

1 – Connect the supplied AC Adapter to the 12vdc jack when the battery needs charging.
The ET312 may be used while charging.

2 – Make sure the unit is OFF and connect the desired accessories to the output jacks.
Both plugs of each leadwire must be connected to an electrode surface to form a complete

circuit for current to ow. Keep all connections below the waist and follow the directions

supplied with your accessories.

3 – Turn on both Level controls all the way down (to the left).

4 – Press the power switch in to turn ON the power.

5 – Use the white Up/Down keys to select the desired mode (see section 10). The name of
each mode is displayed on the LCD.

6 – Set the Level and MultiAdjust controls to produce the desired stimulation. More
information can be found on pages 6 - 15.

4: SAFETY

Be sure you have read the Important Safety Information printed at the front of
this Guide. Like many things in life, electrostimulation is not without risks. It must

be performed properly and there are certain people who should not use ANY
electrostimulation devices including the ET312 — this includes anyone with a
heart condition.

In general, electrostimulation should only be performed below the waist. It is extremely

important to avoid passing current through the heart, neck, or head areas. You need only
grab a bare metal connector or electrode when the unit is on and wired to at least one
other point on the body. The current will travel from below your waist, through the heart
area and to your hand. Always turn the ET312 OFF when making, changing, or removing

connections.

The ET312 should only be used with accessories and electrodes designed for safe
e-stim. Never make connections to body jewelry or similarly small electrodes. Do not use
electrodes made of toxic metals such as lead solder. If you intend to use the ET312 on
someone else, you should experiment with it on yourself before connecting it to someone
else. Also, avoid splitting a channel to connect more than one person at a time.

12 VDC Input - This is where you connect the supplied AC Power Adapter to charge the

battery. Use only the adapter supplied with your unit or one approved by ErosTek. Early
ET312s came with a 12VDC unregulated adapter that had a xed input voltage — 120
VAC in the USA and 240 VAC in EU and other countries — and a variable output voltage
which depended on the load applied. The newest ET312s ship with a worldwide universal
AC adapter that provides a regulated output of 15VDC and comes with different AC plugs
to connect to most power outlets. In either case, an output having a center positive (+)
polarity with 500mA rating is required for connection to the ET312. Connecting a higher

output voltage or one with the wrong polarity will most likely damage the charging circuit
inside the ET312.

Output A & B - The output jacks are labeled “A-Out-B” and each operates independently.
Most erotic accessories will either plug right into these jacks or can be used with the
supplied banana plug cables. If you want to use TENS style pads, or certain other
electrodes, we stock a range of cables, adapters and accessories on our online shop. You
can also purchase 3.5mm (1/8”) 2 conductor (mono) plugs and cables at your ErosTek
dealer or local electronics store. Always make connections with the ET312 turned OFF.

Audio Input - Using the supplied stereo cable, you can connect most any audio device
with a headphone jack to this input. Some common audio sources include portable music
players, smartphones, the sound output from a computer or “sound and light” relaxation
devices. You may want to use a widely-available “Y” cable allowing you to connect both the
ET312 and your headphones to the audio device. Disconnect audio devices when you are

not using them. Audio devices should only be used in the audio modes.

Microphone Input - Connect the supplied microphone to this input for creative audio
stimulation. Other microphones may also be used. See Advanced Topics section A5 for
more information.

Link Connector - This is a proprietary digital interface that serves multiple purposes.
First, it allows the ET312 to be connected to a personal computer running ErosLink™
software (see section A6). The cable and software are available separately. Second, it

allows two ET312 units to be connected together in a master slave conguration. The

slave unit will “mirror” what the master unit is doing providing four channels of stimulation
controlled from one unit. Linking two units requires an inexpensive optional Link Cable
available from our online shop, or you can fabricate your own — see Section A2.

IMPORTANT! — Make certain you never connect an audio device, computer, or

microphone, to the A or B Output jacks! While this will not harm the ET312, it can easily

damage the external equipment. Unfortunately, the erotic e-stim industry standardized
on a common audio connector for their accessories. This makes it easy to plug things
into the wrong jacks and subject external equipment to the e-stim signals. Always make

connections with the power turned OFF.

7: ACCESSORIES

You’ll need erotic accessories or electrodes that allow the ET312 to be connected to the
body. A wide variety of erotic electrodes are available and selection is a matter of gender
and personal preference. ErosTek or your dealer can assist you in choosing the best ones
for your interests.

Your ET312 comes with:

• Universal AC adapter with plugs for US/Canada, EU and UK outlets

• (2) Banana Plug Leadwire Cables

• 3.5Mm Stereo Audio Cable

• High-Sensitivity Microphone

8: CONTROLS

The ET312 offers a wide variety of e-stim options yet is very easy to use. There are multiple
e-stim patterns or routines available. These are called “Modes.” You can further tailor each
mode to your tastes.

For normal operation, simply make the desired connections, make sure that output levels
for both channels, A and B, are at their minimum, turn the ET312 ON, choose a mode, and
gradually increase the output level. The MultiAdjust control can be used to easily ne-tune
the sensations.

Refer to the Front Panel Diagram on the next page for control locations and descriptions.

Power Switch - The power switch is located just to the left of the connection jacks. Make
your connections and turn the level controls fully down before turning the ET -312 on. Push
the button in to turn the unit on, and push it again to turn it back off. Don’t forget and leave
the ET312B ON without it being powered by its AC adapter. Allowing the battery to go

dead can cause permanent damage and reduce the operating time. Replacement battery

modules are available from ErosTek.

Level A & Level B - These adjust the output intensity for each channel. Fully
counterclockwise (to the left) is all the way down. The intensity level is shown on the LCD
from 00 to 99. It is normal to feel the output sometimes increase in small “steps.” It is also

normal for the displayed level to skip a number with gradual adjustments.

MultiAdjust (MA) - This “smart control“ adjusts the optimum parameters for most
modes. After you’ve selected a mode, and set the Level control(s), use the MA control to

ne tune the output for the desired effect or to provide added variety. In some modes, the

MA control may take a few moments to respond.
