Foreword

Our weather-resistant telephone is a captivating product on account of
its precision, convenience, long service life and reliability. It is freely
programmable and the optimum choice for adverse ambient conditions.
Be it seawater, high atmospheric humidity, dust or the toughest
mechanical strains, the weather-resistant telephone accomplishes its
aim in any conditions. The reason for this is the robust keypad made of
V4A steel and an extremely solid housing made of impact-resistant and
shockproof cast-moulding material. All of the components utilised are
even resistant to leeches and lubricants. The 21-component V4A-steel
keypad - which can be operated by a user wearing gloves - and the
easily readable alphanumeric display as well as the uncomplicated
menus all ensure simple operation - thus fulfilling the requirements for a
leading-edge and operationally reliable means of communication. As a
telephone suitable for connecting to the public telephone network and to
private automatic branch exchanges, the ResistTel always ensures
reliable connections.

ResistTel ZB is designed for telephone exchange operation and
corresponds to the ResistTel, except for keypad and display.

General operating instructions

1. Both the weather-resistant ResistTel telephone and the ZB version
are designed for connection to dial ports with analogue connection
points.

2. The handset is fitted with a stray-field coil for connecting hearing­aids. People who use hearing-aids which have an inductive receiver
can receive the earphone signal directly.

3. The optional, external loudspeaker has three operating modes –
calling/ringing, open listening and hands-free. If the external
loudspeaker is switched on, the internal loudspeaker volume will be
reduced.

4. The ZB version is not equipped with keypad and display, therefore
not all the features are available with this version.

5. The ResistTel has a handset module with a dry reed contact as a
hook switch. In order to terminate an existing call connection, the
handset must be hung up. In order to interrupt an existing call
connection, it is sufficient to press the clearing key on the
keypad.(see page 8)

6. Use the menu to program the appropriate settings. To access the
menu, pick up the handset and press the "YES" key.

7. If you take longer than 2 minutes before you begin making a choice,
the power supply of the exchange may be switched off. If that
occurs, you will no longer hear a dialling tone. In that case, please
replace the handset and wait 2 seconds before picking it up again.

8. When a setting is stored successfully, this is confirmed by an
acknowledgement tone.

9. When you receive a call, the ResistTel rings at the ringer-volume
level selected by you and, for the duration of the calling sound, the
symbols ( ( ( ) ) ) appears on the display.

10. If you enter a PIN with the menu you can restrict or block dial
functions. Forgetting the PIN is the equivalent of losing a key. If you
forget the PIN, please contact our technical support.

11. You have a guarantee period of 24 months commencing from the
date of purchase. If you have a problem, please contact our
technical support in Germany, located in Mülheim an der Ruhr:

Contents after unpacking

The delivery includes:

- ResistTel telephone

- Operating instructions

- 2 self-adhesive lettering plates

ZB version notes

The ResistTel / ZB connects – depending on the features of the PABX –
with the PABX while lifting the handset. The ResistTel / ZB can be
called also, because the ringing circuit is built in.

Furthermore there are interfaces for operating an optional second
earpiece, an optional secondary ringer and an optional external
loudspeaker.

The operating mode „external loudspeaker“ is set up by bridging the
terminals 9 and 10 (HSS1,HSS2). With the ZB version this is equivalent
to the open listening mode. The ringer sound is also output via the
external loudspeaker.

Note:
The set up of the external loudspeaker reduces the volume of the
internal ringer even if the external loudspeaker is not connected.

Thus the ZB version offers the following features:

• Establishing a connection by lifting up the receiver

• Ringing by means of integrated ringing device

• Connection of second earpiece

• Connection of secondary ringer

• Connection of external loudspeaker

10

Assembly and installation

The device must be installed on a plane surface only, in vertical
operating position. Loosen the cover screws (2) (see overview of the
device on page 5 to 7). and detach the upper part of the telephone (1).
If the optional accessory headset or a second earpiece is being
employed, attach the bracket (10) using two screws (11) to the rear
panel of the lower part of the telephone. (With the accessories named
before, the bracket and screws are in the scope of delivery. With all
accessories a cable gland is delivered.) Put four screws, having a head
diameter of 10 to 13 mm into the holes (20) and attach the lower part of
the telephone (3) to the wall or to a holder.
Guide the telephone wire through the cable screw cap (4) and place it
on the terminals 13 and 14 (A, B) in accordance with the connection
diagram. Only wires having a sheath diameter of 5 to 9 mm should be
used because otherwise the IP66 housing protection standard is not
guaranteed.

Connecting a second ringer (bell-shunt) (optional accessory)
Remove the sealing plug (5) and tighten the M20x1.5 cable gland
cap. Insert the wire of the second ringer and place it on the terminals
in accordance with the connection diagram. Only utilise wires which
have a sheath diameter of 5 to 9 mm because otherwise the IP66
housing protection standard is not guaranteed.

Connecting an external loudspeaker (optional accessory)
Remove the sealing plug (6) and tighten the M20x1.5 cable gland
cap. Insert the wire of the loudspeaker and place it on the terminals
11 and 12 (SPK+,SPK-) in accordance with the connection diagram.
Only utilise wires which have a sheath diameter of 5 to 9 mm
because otherwise the IP66 housing protection standard is not
guaranteed.

Connecting a headset (optional accessory)
Remove the sealing plug (6) and tighten the M20x1.5 cable gland
cap. Guide the specially-manufactured wire with the headset socket
(included in the delivery of the headset) through the cable screw cap
and place it on the terminals 5 through 10 (HSM+, HSM-, HSR+,
HSR-, HSS1, HSS2) in accordance with the connection diagram.
Only the wire included in the delivery for the headset should be used
because otherwise the IP66 housing protection standard is not
guaranteed.

11

Connecting a second earpiece (optional accessory)
Remove the sealing plug (6) and tighten the M20x1.5 cable gland
cap. Insert the wire of the second earpiece and place it on the
terminals 7 and 8 (HSR+, HSR-) in accordance with the connection
diagram.

Prior to assembly, check cover seal for tightness.
Using the plug connector (7), plug the ribbon cable onto the pin contact
strip (8) in the upper part of the housing.
Attach the upper part of the telephone and fasten it to the lower part of
the telephone with the four cover screws (2).
Upon disassembly of optional accessories, suited blind plugs must be
used to close the resulting openings.
