7. PROGRAMMING
The TLS376E1S telephone is designed to facilitate programming remotly over a telephone
line. Programming is carried out using sequences keyed from a DTMF telephone, when
connected to the TLS376E1S telephone to be programmed.
7.1 PROGRAMMING CODES
IMPORTANT :
Before all programming, key the access code : *1234* (factory setting) or as
changed by the user (see function 12/13 below).
The acceptance sequence is a single beep if memory M0 (see function 18 below)
if empty or a single beep followed by the contents of Memory 0 folloxed by « * »
if memory M0 has been programmed.
Non-acceptance is indicated by « no-response » in which case it is necessary to
try again.
Proceed with programming as follows :
For each programming sequence below the telephone gives an acceptance/non-acceptance
sequence. The acceptance sequence is a mix DTMF tones (functions N° 1, 5 and 18 below)
or a single beep (all other functions).
In all cases the non-acceptance sequence is two beeps.
If the non-acceptance sequence is received, it is necessary to try again.

1 AUTODIAL NUMBERS (If no chaining is required)
If chaining is required, use function N°5 instead (page 14)
During memory programming , the combination #11#
represents the recognition of a continuous tone with a
frequency of 440 Hz ±100Hz (standard) before dialling.
PROCEED AS FOLLOWS :
Program button :
N = autodial number from 1 to 15 digits.
Program empty memory :
*5001*#11#N*
*5002*
2 TYPE OF DIALLING / CONFIGURATION
Although this equipment can use either loop disc or DTMF
signalling only the performance of the DTMF signalling is
subject to regulatory requirements for correct operation. It
is therefore strongly recommanded that the equipment is
set up to use DTMF signalling for access to public or
private emergency services. DTMF signalling also
provides faster call set-up.
For configuration, each function has a value as follows:
1/ DTMF dialling and automatic cleardown. 00
2/ For pulse dialling and automatic cleardown. Key the
combination :
*1000*
*1001*
3 LOUDSPEAKER VOLUME
V= volume from 1 to 9 (factory setting = 5) *140V*
4 RINGING VOLUME
V= volume from 1 to 7 (factory setting = 7) *160V*

5 PROGRAMME A NUMBER CHAIN
It is possible to program a number chain, so that, for
autodial buttons, if the first number dialled is busy or does
not answer, the telephone will dial one or more alternative
number in a ‘chain’ until successful connection is made.
All telephone numbers programmed into the chain must
be different, no number may appear more than once.
THE STEPS TO TAKE ARE :
Program the main number in memory 1 and additional
numbers in memories 2-8.
Program an empty memory following the last number
entered, e.g., if two numbers are programmed, Memory 3
should be empty :
To program the interval between memory auto-dial
attempts
T1 between M1 – M2 and
T2 between M2 – M3, M3 – M4 etc… if necessary
These times are the intervals in the event of no-answer
before dialling the next number.
For T1 key :
TT is the time in seconds. If only one number TT=00
For T2 key :
If chaining 2 or several numbers, 2 choices are possible :
a) to hear what actually happens on the line : program
T1/T2 with even number *e.g. 30 sec.)
b) to mask what happens on the line (no-answer, busy
tone, ..) until the called party picks up, by simulating
ringing and flashing LED. On detection of speech from
the called party, a long beep announces to both parties
that the communication has been established, the LED
shows constant. For this, program T1/T2 with an odd
number (e.g. 31 sec.)
*500M*#11#N*
M (memory) =
1,2,….8 max.
N= Call number
up to 15 digits
The chain stops

NUMBER OF RINGS BEFORE AUTOMATIC ANSWER
In the factory, the telephone is set to answer automatically
after 3 rings. To change this number, key :
NN= 00 to 99
NN= 03 factory setting (answer automatically after 3 ring
or manually by pushing the button)
NN= 00 automatic answer with no ringing (suitabel only for
programming)
NN= 99 No automatic answer (answer only manually by
pushing the button)
Important note :
Where 00 is programmed, both microphone and
loudspeaker are de-activated on auto-answer, where 01-
98 is programmed, the microphone is de-
activated on auto
answer (but the loudspeaker is active). The microphone
can be activated by pushing any butt
on. If, in this case,
the telephone receives programming signals (from an
operator or call-centre system, the loudspeaker is de-
activated. It can be re-activated by keying the code

8. MAINTENANCE
The TLS376E1S telephone requires little maintenance to remain in excellent operational
condition.
Carry out the following maintenance if necessary.
E XTERNALLY
Clean using a dampened soft cloth to remove dust and dirt. For grease, a little soap may be
used.
If you use a high pressure hose (preferably 50 bar) do so from a distance of about 1.50m
(5ft) from the telephone.
I NTERNALLY
The telephone requires no internal maintenance. Do not insert any fluid into the telephone
set.
W EATHERPROOFING
At least once a year and otherwise whenever closing after opening check thoroughly the
effective weatherproofing of the joints, seals and apertures and state of the silicon sealant
and repair or replace as appropriate (see Note – page 4).
GRAFFITI
Where graffiti have been sprayed or painted on to the surface of the telephone and cannot
be removed the telephone may be re-painted using Epoxy paint colour orange RAL2008 or
BROWN RAL8007. The surface of the telephone should first be washed with a detergent
and rubbed down with an abrasive.
9. IN THE EVENT OF A PROBLEM
Before consulting the maintenance service, we advise you to check the following points:
P ROBLÈM WITH LINE CONNECTION OR DIALLING :
•Check telephone line correction on the connection terminal (see page 14)
•Check the button is not jammed by foreign object.
T RANSMISSION PROBLEM
•Check the setting of jumper ST1 (see page 13)
•If transmission if weak, check that the microphone holes are not blocked by a foreign
object.
R ECEPTION PROBLEM
•If transmission if weak, adjust the reception to the level required.
