Thank you for choosing a quality product from BHM-Tech. The pan digital hearing system

is manufactured in Austria in line with the regulations laid down in Medical Device Directive

93/42/EEC and latest audiological findings and technical innovations. It bears the CE mark and

satisfies the latest quality and safety requirements. The following pages are directed at hearing

aid acousticians/doctors and show proper fitting and adjustment of the pan hearing system.

Purpose

Hearing systems are developed to improve hearing. The key functions of a hearing sys-

tem are the sound pick-up, amplification and reproduction of the signal to the ear drum

of those with impaired hearing. Your hearing system lends itself to the compensation

of sensorineural and combined hearing loss, and the pan Ti also to the combating of

tinnitus.

Warning information for hearing aid acousticians

When selecting and adjusting hearing systems whose maximum sound pressure

level can exceed 132 dB SPL (ear simulator), particular caution must be

exercised because there is a risk of damaging the residual hearing of the

hearing system wearer.

Prior to using the hearing system, reassure yourself of its functionality and proper

condition. The hearing system should not be used under any circumstances if there is

a suspicion it does not work perfectly or is damaged.

The pan hearing system is suitable for mounting onto virtually every pair of spectacles.

Patent pending GM 136/2013

Preparation of the temple

To prepare the temple, remove the temple from the front of the spectacles if required. The

temple is cut to length at marking A using a suitable tool (such as with side-cutting pliers)

and the plastic is stripped to the wire core at marking B (Fig. 6). Then the cut surface has

to be worked with a suitable tool as required (such as a file or sandpaper) - Fig. 6.

Note: When using spectacles with metal temple, this must be cut at marking A using a

suitable tool (such as side-cutting pliers) and be adjusted to the shape of the inner profile

of the adapter at marking B (Fig. 7).

Determining the temple length

To determine the correct temple length, use the fitting template supplied (Fig.1). Ensure the

wearing position of the spectacles is correct.

Use a pen to mark Points A and B by putting the fitting template onto the spectacle

temple (Figs. 3 to 5).

Cosmetic adjustment of the temple

The temple must be adapted cosmetically to the hearing system by cutting, sanding or

similar such that a smooth transition is created (Fig. 8).

Mounting the adapter

Clean the protruding wire core with spirit. The glued surface must be free of grease (Fig. 9).

Included with the product is an adapter ring with different adapters suitable for different wire

cores (Fig. 10). Select from them the adapter suitable for your temple.

Apply glue to the wire core and the cut surface and fit the adapter onto the temple. Ensure

the adapter sits straight and secure (Fig. 11).

Recommendation: Cyanoacrylate quick-action glue with low viscosity (such as

Loctite 406) Hardening time: approx. 2 minutes.

The indent must be on the underside when fitting

Mounting the hearing system

Mount the hearing system onto the adapter and secure it using a BHM pin setter and locating

pin (on the adapter ring) - Fig. 12.

Individual fitting

Individual fitting (Figs. 13 to 15) is possible after adequate warming of the hearing system by

using hot air only on the area specified in Fig. 13 using a frame warmer. The hearing system

may only be heated uniformly in the area stipulated. Please do not use any tools such as

pliers because damage to the plastic material may result.

WARNING: RISK OF BURNS – ENSURE THAT ALL THE PARTS OF THE HEARING SYSTEM HAVE

COOLED BEFORE COMING INTO CONTACT WITH BODY PARTS!!!

CAUTION: When bending the hearing system, never use a naked flame for heating. This can

cause damage to the hearing system. Only the frame warmer with slit nozzle provided may

be used for heating. Max. temperature: 60 degrees Celsius / max. 45 seconds

External receiver

Use the audiogram, the condition of the auditory canal and the datasheet to decide

whether your customer requires a Normal Power (Fig. 16) or High Power receiver

(Fig. 17).

Determining the receiver tube length

At the same time as determining the temple length, the fitting template is used to determine

the correct length of the external receiver tube length, as shown in Fig. 18. Lengths 0, 1, 2

and 3 are available. The value in the centre of the auditory canal is read to determine the

receiver tube length (Fig. 18).

Selection and mounting of the earpiece

Use the condition of the auditory canal to select the earpiece suitable for your customer

and fit it onto the external receiver (Figs. 21 and 22).

Note there are different earpiece types for Normal Power and High Power receivers

(Figs. 19 and 20).

Mounting the High Power earpiece

Cerumen Filter HF3 Mounting tool for High Power earpiece Fit the earpiece over the adapter of the mounting tool.

Open the earpiece by pressing together the mounting tool.

Insert the High Power receiver into the open earpiece. Carefully remove the

mounting tool.

Ensure that the earpiece is

fully on the mounting tool.

Removing the HF3 filter

Press the HF3 filter as far as it will go into the High Power earpiece.

Hold the earpiece and filter at the end and release the

tool from the filter by turning.

Adaptation of the receiver

The tube shape of the receiver can be adapted as follows if required:

Place the receiver into the protective sleeve provided (Fig. 26). Rotate the spiral spring onto

the receiver tube (Fig. 27). Adapt the receiver shape to the customer and heat the receiver

tube using the frame warmer (Fig. 28).

Allow the receiver to cool for at least one minute and remove the spiral spring and protective

sleeve (Fig. 29).

Mounting and dismounting the receiver

See Figs. 23 to 25 for fitting and removing the receiver.

Special cases

If the customer has a spectacle frame from Coselgi or BHM-Tech, we offer special adapters

for these (Figs. 30 and 31). When using the pan with these adapters, an overall length as

with existing BHM-Tech and Coselgi hearing temples is attained. This means no subse-

quent preparation of the existing glasses is necessary.

Connection for programming

Note: No battery needs to be inserted for programming.

Remove the programming socket cover and plug the connector of the programming cable

into the programming socket (Fig. 32).

Note: Ensure that the red marker on the programming cable connector is on the same

side as the marking on the housing (no connection is established otherwise).

Fitting software

To guarantee problem-free function, only use BHM-Tech software approved for this pro-

duct. Please refer to the „BHMFitpan“ software description for details on the programming

process. Please contact your vendor or BHM-Tech Produktionsgesellschaft mbH if you re-

quire clarification.

After the programming process, remove the programming cable and put on the programming

socket cover. If the hearing system is not used for a longer period, keep it in the original

packaging without batteries in a safe place not accessible to anyone unauthorised.
