Technical specifications:
Optionally 230 V or 120 V version
ATTENTION!

• If you do not use the device for a long time or take it with you while travelling, please remove the batteries and rechargeable batteries from the grip.
• New batteries should be inserted when the light intensity of the instrument becomes weaker.
• In order to obtain an optimal light yield, we recommend that you always insert new high-quality batteries when changing the battery (as described in 3.1 and 3.2).
• If there is a suspicion that liquid or condensation has penetrated the grip, it must not be charged under any circumstances.
• This can lead to a life-threatening electric shock especially with regard to the socket hand-
• To extend the battery life, the battery should not be charged until the light intensity of the
  instrument becomes weaker.

Disposal:

Please note that disposable batteries and rechargeable batteries must be disposed of in a specific way. You can obtain information in this regard from your local community or from your responsible environmental advisor.

Putting on the instrument head

Place the instrument head onto the mount on the upper part of the grip so that the two recesses of the lower part of the instrument head rest on the two protruding battery grip lugs. Press the instrument head lightly onto the battery grip and turn the grip clockwise until it stops. The head is removed by turning it anti-clockwise.

Switching

Battery grips type C and AA on and off. Turn on the instrument by moving the switch ring on the top of the grip in a clockwise direction. To turn the instrument off, turn the ring anti-clock-wise until the unit turns off.

rheotronic® to regulate the light intensity

With the rheotronic®, it is possible to adjust the light intensity on the type C and AA battery grips. The light intensity will be weaker or stronger depending on how often you move the switch ring in the clockwise or anti- clockwise direction.
ATTENTION!
Each time the battery grip is turned on, the light intensity is 100%. Automatic safety shutdown after 180 seconds.
Explanation of the sign on the socket handle:
Attention, follow the user manual!

EliteVue

Purpose/indication

The Riester EliteVue was used to illuminate and examine the ear canal and eardrum in combination with the Riester ear funnels produced.

Caution/contraindications

• There may be a risk of ignition of gases if the instrument is used in the presence of flammable mixtures or mixtures of pharmaceuticals.

• The product and the ear funnel are non-sterile. Do not use on injured tissue. Use new or sanitized funnel to limit the risk of cross-contamination.

• Used ear funnels must be disposed of in accordance with current medical practices or
  local regulations regarding the disposal of infectious, biological medical waste.

• Only use accessories/consumables from Riester or Riester-approved accessories/consumables.

• Cleaning frequency and sequence must comply with regulations on the cleaning of non-sterile products in their respective facility. Cleaning/disinfection instructions in the operating manual must be observed.

• The product may only be used by trained personnel.

Placing and removing ear funnels

Disposable ear funnels can optionally be selected for equipping the Riester (in black colour) or reusable Riester (in black colour) ear funnels. The size of the ear funnel is marked at the back of the funnel.
L1 and L2 funnels
Turn the funnel clockwise until you feel resistance. To remove the funnel, turn the funnel anti-clockwise.
L3 funnel
Place the selected funnel on the chromed metal frame of the otoscope until it clicks into place. To be able to remove the funnel, press the blue eject button. The funnel is detached automatically.

Focusing wheel

With the focusing wheel, you have the option to set the focus range in the ear canal (eardrum). Due to the high quality lens system, you have a 5.5x magnification and a field of view diameter of 11 mm at a distance of about 20 mm.

Pneumatic test

In order to be able to perform the pneumatic test (= an examination of the tympanic mem-brane), you need a ball which is not included in the normal scope of delivery, but which can be additionally ordered. The tube of the ball is fitted to the connection. You can then carefully introduce the required amount of air into the auditory canal.

Medical electrical equipment is subject to special precautions regarding electromagnetic compatibility (EMC).
Portable and mobile radio frequency communication devices can affect medical electrical equipment. The ME device is for operation in an electromagnetic environment or home health care and is intended for professional facilities such as industrial areas and hospitals.
The user of the device should ensure that it is operated within such an environment.
Warning :
The ME device may not be stacked, arranged or used directly next to or with other devices. When operation is required to be close to or stacked with other devices, the ME device and the other ME devices must be observed in order to ensure proper operation within this arran-gement. This ME device is intended for use by medical professionals only. This device may cause radio interference or interfere with the operation of nearby devices. It may become necessary to take appropriate corrective measures, such as redirecting or rearranging the ME device or shield.
The rated ME device does not exhibit any basic performance features in the sense of EN60601-1, which would present an unacceptable risk to patients, operators or third parties should the power supply fail or malfunction.
Warning:
Portable RF communications equipment (radios) including accessories, such as antenna ca-bles and external antennas, should not be used in closer proximity than 30 cm (12 inches) to parts and cables of the EliteVue instrument head with hand grips specified by the manu-facturer. Failure to comply may result in a reduction of the device‘s performance features.

Recommended separation distance d = 1.2 × P 80 MHz to 800 MHz d = 2.3 × P 800 MHz to 2.7 GHz
Where P is the maximum output power of the transmitter in watts (W) according to the transmitter manufacturer and the recommended distance is given in meters (m).
Field strengths from fixed RF transmitters determined by an electromagnetic site survey should be less than the compliance level in each frequency range.
Interference may occur in the vicinity of devices marked with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. The electromagnetic propagation is affected by absorption and reflection of structures, objects and people.

• Field strengths of fixed transmitters, such as base stations for radio (cellular/wireless) telephones and land mobile radios, amateur radio, AM and FM broadcast and television transmissions, cannot be theoretically predicted with accuracy. In order to assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic survey should be considered. If the measured field strength at the location where the EliteVue is used exceeds the above-mentioned RF degree of compliance, the EliteVue should be observed to ensure normal operation. If abnormal performance is observed, additional measures may be required, such as reorienting or moving the EliteVue.
• With a frequency range over 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.

Recommended distances between portable and mobile RF communications equipment and the EliteVue

The EliteVue is intended for use in an electromagnetic environment in which RF emissions are controlled. The customer or user of the EliteVue can help to avoid electromagnetic interference by observing the mini- mum distance between portable and mobile RF communications equipment (transmitters) and the EliteVue in accordance with the maximum output power of the communication equipment.
Rated maximum output power of the transmitter (W)| Separation distance according to the frequency of the transmitter (m)
| 150 KHz to 80 MHz| 80 MHz to 800 MHz| 80 MHz to 2.7 GHz
0.01| | 0.12| 0.23
0.1| | 0.38| 0.73
1| | 1.2| 2.3
10| | 3.8| 7.3
100| | 12| 23
For transmitters with a maximum output power not listed above, the recommended distance d in metres (m) can be estimated using the equation for the transmitter frequency, where P is the maximum output power of the transmitter in watts (W). according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance applies to the higher frequency range.
NOTE 2 These guidelines may not apply in all situations. The electromagnetic propagation is affected by absorption and reflection of structures, objects and people.
