3.5.1.1 Vaginal, anal or rectal stimulating probes
For the treatment of e.g. several incontinence problems.
The Duo 500
recognizes the vaginal and the anal probes (= probes equipped with a DINconnector). As soon as one of these probes is connected, the unit will only select
alternating currents (TENS, NMES, and bipolar interferential currents) with a Constant
Voltage (CV) setting. All other current shapes may not be selected at that time
Chapter 14: SPECIFICATIONS.)
. (See also
WARNING:
The Duo 500 DOES NOT RECOGNIZE THE RECTAL PROBE and thus allows in principle
the use of all sorts of current shapes whenever connected.
In order to avoid unpleasant sensations and cauterisation or etching we advice to utilize
exclusively selected Constant Voltage settings (TENS, NMES, and bipolar intermediate
frequency currents) when using a rectal probe
See paragraph 7.7 for more information about the Constant Voltage.

3.6 Functional test
− During production the Duo 500 is thoroughly checked for electrical safety.
− When switching on the Duo 500, the microprocessor is performing an extensive test In
order to verify the correct functioning of the unit.
− Check if the display is functioning properly. If this is not the case, do not continue to use
the device and inform the repair services of your local Gymna dealer.
3.7 New owner
The ‘Medical Device Directive’ of the European Commission (93/42/CEE) prescribes that
this type of medical equipment should be traceable. That is why we are kindly requesting
every (new) owner to urgently give to the local Gymna dealer the name, address and other
relevant data of the
new owner.
3.8 Liquidation
Turn in the Duo 500 and all its accessories to a company specialised in the liquidation and
recycling of electronic products and components. In those countries where there is a “take
back” option in force, please contact your local Gymna dealer.
In the event that the owner is willing to destroy the unit himself or if he is willing to take the
responsibility for doing this, the following information concerning environmental
consequences might be interesting.
The parts of the Duo 500 can be classified into three categories:
1) The basic units, wiring, electrodes and the Treatment Guide are to be considered as
electronic or as small chemical waste. They consist of, amongst others, lead, tin,
copper, iron, a diversity of other metals and several man-made materials. In most of
the countries this waste is classified as “small chemical waste”. Refer to the national
regulations in force in your country for that matter.
2) Sponges, sponge sachets only hold organic material and therefore do not need any
special attention.
3) Packaging materials and the Operating instructions can be recycled. Depending on
the local organization of the waste disposal, they have to be turned in at dedicated
collecting points or they have to be evacuated with the regular dustman/ garbage
man.
NOTE:
In most of the countries it is not allowed any more to dispose off these kinds of appliances through the regular
garbage disposal channels (because of the man-made plastics and of the electronic components).

6 GENERAL OPERATING INSTRUCTIONS
6.1 Introduction
The Duo 500 offers numerous possibilities and still remains very easy to operate. The
operating principle is logical and consistent. As soon as one gets acquainted with the
functions of the various keys and controls, the operational use of the unit is self-explanatory.
In this chapter, the functions of the keys and controls not yet treated previously will be
discussed.
See Chapter 4: CONTROLS for a short and concise description of the controls, the numbers of these controls
correspond to the numbers of the exploded view of the Duo 500 unit and its accessories in the beginning of
these Operating Instructions.
See Chapter 7: SOME PARTICULAR THERAPEUTICAL AND PARAMETER POSSIBILITIES.
See Chapter 18: INDEX for the alphabetical index. Here one can quickly find out on what pages of the Operating
Instructions the specifically searched reference is discussed.
