LEDI 6 – LEDI 6/S
5 /8
3.2 - STANDARD and WATERTIGHT cases
3.2.1 - Impulse or AFNOR code receiver
In the case of a polarised impulse or AFNOR NFS 87-500 code receiver clock, connect the impulse or code
input to terminal B1 and connect this to the bottom. The clock will then be automatically converted from
autonomous to receiver version
3.2.2 - Radio-synchronised version
In the case of a radio-synchronised clock, connect the antenna to terminal B1.
It may be necessary to carry out the initial setting manually (in the event of a disturbance in the radio
signal or momentary break-down of the DCF transmitter). In this case, proceed in the same way as for
an autonomous clock (see section 4 - Setting).
4 - SETTING
(fig. 4)
The time is set by using the "+", "-" and "PROG" keys at the back of the clock (in the case of the
watertight cases, slightly loosen the knurled knob and open rotate the access flap).
Each time the "PROG" key is pressed, a different part of the display begins to flash. This is then
modified by using the "+" and "-" keys. The figures can be advanced quickly by pressing continuously
on these keys.
The setting cycle is as follows:
1
adjustment of time display time (from 1 to 9 seconds)
2
adjustment of temperature display time (from 1 to 9 seconds)
3
adjustment of hours
4
adjustment of minutes
SYNCHRONISATION
If the minutes have not been modified, one press on "PROG" will validate the new time setting without
modifying the initial synchronisation (e.g. modification of time/temperature alternation or seasonal
changeover for autonomous clocks).
If the minutes have been modified, one press on the "PROG" key will make the entire display flash,
indicating that the clock is in synchronisation phase. A second press on "PROG" will enable the clock
to be synchronised (this should be done on a time signal given by a reference clock, e.g. the speaking
clock). The display will then stop flashing.
REMARKS
- The first two cycles (time/temperature alternation) only apply in the case of a clock with the
temperature display option. On initialisation, the default duration for the time display is 4 seconds and
that for the temperature display 2 seconds.
- All setting phases are limited to 30 seconds, except the synchronisation phase, which can only be
terminated by pressing on the "PROG" key.
5 - BRIGHTNESS CONTROL
The brightness is adjusted by pressing on the "+" and "-" keys when not in the setting cycle or a light-
dependent resistor may be built into the clock to ensure automatic brightness control in accordance
with the ambient lighting.
