869 MHz Radio version
The clock synchronizes itself automatically following the emitting period of the emitter. Waiting the reception,
2 points between the hours and the minutes stay off until one reception was received. Then these points
have a second period blink except a 59th second off during 3 minutes.
2 - MOUNTING
Standard case
(cf. fig. 1 - fig. 2 - fig. 3)
- Prepare the wall support for attaching the bracket. Leave at least 60 mm between the top of the case and
the ceiling.
- Fix the bracket on the wall support using two 4 mm dia. screws.
- Hook the case over the bracket.
Flush-mounted case
(fig. 5)
- Prepare the wall support. LEDI 6: 335 x 151 x 75 mm.
LEDI6/S: 415 x 198 x 75 mm
- Position the support clip in the wall recess.
- Clip the clock on to its support.
Watertight case
(fig. 6 - fig. 7)
- Prepare and drill the wall support.
- Fix the “LEDI’s support” using three M5 screws
- Hang and clip the clock on to its support, taking care to bring out the wires at the top.
3 - CONNECTIONS (fig. 4)
- Connect the 230 V/50-60 Hz mains supply to the 3-conductor cable.
- Flip the battery switch
SW1 to the ON
(lower) position after connecting the clock.
N.B. If the hours and minutes remain unlit, wait a few minutes for the internal battery to be recharged.
3.1 - WATERTIGHT case
All connections are made at the back, without having to open the case. Cables should be connected as
shown by the identification marks.
