Foreword
Our telephone ExResistTel/ExResistTel ZB 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 con-
ditions. 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-button V4A-steel key-
pad - 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 tele-
phone suitable for connecting to the public telephone network and to
private automatic branch exchanges, the ExResistTel always ensures
reliable connections.
ExResistTel ZB is designed for telephone exchange operation and
corresponds to the ExResistTel, except for keypad and display.

General operating instructions
1. Both the ExResistTel 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 hearing-
aids. People who use hearing-aids which have an inductive receiver
can receive the earphone signal directly.
3. The ZB version is not equipped with keypad and display, therefore
not all the features are available with this version.
4. The ExResistTel 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 con-
nection, it is sufficient to press the disconnect key on the key-
pad.(see page 12)
5. Use the menu to program the appropriate settings. To access the
menu, pick up the handset and press the "YES" key.
6. 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.
7. When a setting is stored successfully, this is confirmed by an
acknowledgement tone.
8. When you receive a call, the ExResistTel rings at the ringer-volume
level selected by you and, for the duration of the calling sound, the
symbols ( ( ( ) ) ) appears on the display.
9. If you enter a PIN with the menu you can restrict or block settings
and dial functions. Forgetting the PIN is the equivalent of losing a
key. If you forget the PIN, please contact our technical support.
Customer information
This device has been tested and found to comply with the limits for a
class B digital device, pursuant to part 15 of the FCC rules.
This device complies with part 68 of the FCC rules and with the stan-
dard TIA 968B.
The REN (Ringer Equivalence Number) is used to determine the num-
ber of devices that may be connected to a telephone line. Excessive
RENs on a telephone line may result in the devices not ringing in re-
sponse to an incoming call. In most but not all areas, the sum of RENs
should not exceed five (5.0). To be certain of the number of devices that
may be connected to a line, as determined by the total REN, contact the
local telephone company. The REN is part of the product identifier and
has the format REN n.n.B. The letter B denotes the ringer type.
If this telephone causes harm to the telephone network, the telephone
company will notify you in advance that temporary discontinuance of

6
service may be required. But if advance notice isn´t practical, the tele-
phone company will notify the customer as soon as possible. Also, you
will be advised of your right to file a complaint with the FCC if you
believe it is necessary.
The telephone company may make changes in its facilities, equipment,
operations or procedures that could affect the operation of the device. If
it happens, the telephone company will provide advance notice in order
for you to make necessary modifications to maintain uninterrupted
service.
If trouble is experienced with this telephone, for repair or warranty
operation, please contact your supplier.
If the device is causing harm to the telephone network, the telephone
company may request that you disconnect the device until the problem
is resolved.
If you have specially wired alarm equipment connected to the telephone
line, ensure the installation of this telephone does not disable your alarm
equipment. If you have questions about what will disable alarm equip-
ment, consult your telephone company or a qualified installer.
This telephone must not be used on party lines.
This telephone is of a type that is not intended to be repaired.
This telephone is hearing aid compatible (HAC).

Device
Device – construction
The two-part housing of ExResistTel consists of an electrostatically
conducting compressed material into the top portion of which a stainless
steel front plate is inserted. A cut-out closed with a sight glass in the
front plate, is arranged over the display of the telephone.
A trough for incorporating cast electronic modules, as well as a connec-
tion compartment into which up to four leads can be introduced, is built
into the box shaped lower part. The upper part with keypad and display
section is compressed onto the lower part along with an intermediate
circumventing gasket with the help of four screws and seals off the in-
ternal space.
Variant ExResistTel ZB notes -------------------------------------------------------
ExResistTel ZB is a variant of the telephone that has neither a display
nor a keypad and can be used in centralised operation applications
(ZB). Differing from the identical handling of incoming calls, the ZB
variant is passive during outgoing calls. The private branch exchange
used is responsible for dialling or establishing a voice connection, which
should be configured accordingly if required.
Apart from the display and keypad, the variant ExResistTel ZB has the
technical data of the standard variant ExResistTel at delivery. All keys,
display and setting dependent statements in the operating manual do
not necessarily apply to the ZB variant. The operation with a headset is
also not possible. For a better overview, the use of an explicit identifica-
tion such as "not applicable for the ZB variant" of all affected passages
has been avoided.

Notes:
Automatic key repetition of the telephone is active on opening of
menu functions. After an initial delay of 500 ms, key events are re-
peated at an interval of 125 ms as long as the key is pressed. This
way, the browsing of the telephone directory, the adjusting of sliding
controllers, the shifting of cursor positions etc. is simplified.

Device – mounting and installation
a) The device may only be installed on an even surface and in a vertical
position. Provide the selected area of installation with suitable holes
for fastening the device. The diameter of the drilled hole is depend-
ent on the screw employed (screw diameter max. 5/16” [8 mm]) and
the type of supporting base material (steel, wood, concrete, plaster-
board etc.) and must be chosen accordingly.
