Warnings and security information
This device is a explosionproof, weatherproof telephone especially designed for use in
rough industrial environments.
Please note the following warnings and security information:
– The installation and adjustment of the device must be carried out by qualified per-
sonnel in accordance with the prescribed installation regulations taking the specified
types of protection into account.
– This apparatus is a Protective Class lI device and may only be connected to and
operated at the voltage it was designed for.
Make sure the connections are in perfect order.
– Make sure the telephone housing, the connecting cable and the receiver cord are
not damaged. If the device is damaged, it may not be operated.
– While operating the device in commercial facilities, the accident prevention regula-
tions of the Employers' Liability Insurance Association regarding the use of electrical
systems and devices must be observed.
– The device may be operated solely under the stated ambient conditions. Unfavoura-
ble ambient conditions can lead to damage of the device and thus present a potential danger for the user.
Unfavourable ambient conditions include:
• Humidity of air too high (>75% r el., condensing)
• moistur e, dust (pay attention to the degree of protection)
• flammable gases, vapours and solvents not cover ed by the
device’s type of protection
• too high ambient temperatur es (>+55°C)

manufacturer followed by a renewed product conformity inspection.
– Make sure the wiring is disconnected from the power supply upon connecting or
disconnecting the wires in the terminal room.
– If electrical connections must be carried through in the hazardous area, the enclosu-
re must be opened and closed as follows:
• Remove voltage fr om the device
• Loosen the fastening scr ews from the keypad insert
• Remove the keypad insert and unfasten the keypad cable
4 dFT3 1.1
• Make the connections while the device is open
• When the work is done, plug the keypad back on, and place the keypad insert
back on the lower part of the device.
Make sure the seal is correctly positioned and in perfect working order. Then tighten
the fastening screws in a diagonal pattern.
– Only blind plugs and cable glands as prescribed by the manufacturer may be used.
Should these points not be observed, the explosion protection of the device cannot be
guaranteed. The device then poses a potential threat to the user’s life and can cause
the ignition of an explosive atmosphere.

General operating notes
1. The versions of FernTel 3 can be operated in the analogue, public telephone network
and connected to analogue terminals of branch exchanges.
2. The receiver is equipped with a leakage field spool for coupling of hearing aids. Users
of a hearing aid with inductive receiver may receive the signal from the receiver inset
directly.
3. The version without keypad does not offer you all the performance features available
in other versions.
4. The telephone has a receiver accommodation with a magnetic contact as hook
switch. To terminate an existing connection, the receiver must be replaced. For
disconnecting an existing connection, all you need to do is press the disconnect key
on the keypad.
5. When programming the settings, the handset must be off the hook. On the version
with 16 keys, you enter programming mode by simultaneously pressing the asterisk
and the hash key. For the version with 21 keys and a display, programming takes
place in the Select menu, which appears when the
key is pressed.
6. If a procedure has been completed successfully, you will hear an acknowledgement
signal. An error tone informs you of any operating mistakes.
7. Should more than 2 minutes pass before you start dialling, the exchange may cut off
the power supply. The dial tone can no longer be heard. In this case you should put
the handset back on the hook and wait approximately 2 seconds before you lift it
again. Programming sessions that have been started, but have not been completed,
must be repeated.
8. If you get a call, the FernTel 3 rings with the volume and melody you have chosen.
The display version also signals the incoming call in the display.
9. Entering your personal identification number (PIN) you may partly or completely
restrict functions and settings. Forgetting your PIN can be compared to losing a key.
If you have forgotten your PIN, please contact our technical support service.
