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

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.

Bore
illustration

(not to scale)

Place the telephone in the upper latches (A), swing it downwards until the lower latches
audibly engage (B).
Remove the keypad plate (6), and tighten the two locking screws (3) as far as they will go.
Important: This preserves the IP65 degree of protection.
Pull the telephone line through the cable gland (4) and connect it with terminal (5) TCP/La ­TCP/Lb (TCP : Terminal Connection Point).
Use cables with a sheath diameter of 5 to 9 mm only, otherwise the IP65 degree of
protection can not be guaranteed.

9

Plug the ribbon cable onto the pin contact strip (7) of the keypad plate.
Tighten the keypad plate (6) using four screws (8).

Table version

Place the telephone in the lower latches (A), swing it backwards until the upper latches
audibly engage (B).
Pull the telephone line through the cable gland (4) and connect it with terminal (5) TCP/La ­TCP/Lb.
Use cables with a sheath diameter of 5 to 9 mm only, otherwise the IP65 degree of
protection can not be guaranteed.

The standard handset accommodation (for the wall version) (9) can be replaced for the table
version.
After loosening the two screws (12) on the bottom of the keypad plate you can remove the
standard handset accommodation.
Fasten the table version handset accommodation (11) to the keypad plate by using the
included screws (12).
Plug the ribbon cable onto the pin contact strip (7) of the keypad plate. Tighten the keypad
plate (6) using four screws (8).

Lay the telephone cord according to the instructions, in order to prevent accidents.

10

Mounting the sling holder (optional)

Remove the keypad plate (6) by loosening the screws (8).
Lever out the duct cover (13).
Fasten the sling holder (14) by using the two included screws (15).
Insert the duct cover (16) with groove.
Screw the keypad plate (6) back on again.

Connection of a secondary sounder

If you want the telephone to control a secondary sounder, the blind plug must be replaced by
a cable gland M20x1.5 IP65. The cable diameter must correspond to the demands of the
cable gland, otherwise the IP degree of protection will not be reached. Remove the keypad
plate, install the cable gland and connect the secondary sounder to the terminals W and W1.
After all the connections are made, screw the keypad plate onto the housing again, using 4
screws (8).

General information

Service

You have bought a modern FHF product subject to meticulous quality control. If any
questions regarding the telephone, or malfunctions should occur – even after the guarantee
has expired – please contact FHF. Please have the type denomination and product number
(to be found on the nameplate) ready.

Care and maintenance

The telephone is maintenance-free. Still, if the operating area is highly contaminated by dust,
fat, oil etc., the device should be cleaned from time to time. Use a moist cloth to dust off the
handset and the device.
Warning! Never use sharp objects for cleaning. Do not use other polishing or abrasive
substances.

Warnings and security information

This device is a weatherproof telephone especially designed for use in rugged industrial
environments. Please note the following warnings and security information:

1. The telephone is a Insulation Class II device and may only be connected to and
operated at the voltage it was designed for. Make sure the connections are in perfect
order. The connecting cable must be laid in a manner not to cause a tripping hazard.

2. The telephone may only be operated at the given ambient conditions (see also under
“Technical data”). Adverse ambient conditions, as for instance too high or too low
ambient temperatures are not allowed, due to increased risk of an electronic parts
breakdown.
