The first thing that must be checked when we have a break down is whether the LED on the button

panel lights up green. If it does not light up or lights up red, permanently or intermittently, follow

these steps:

1.Substitute the battery to discard the possibility of it not being charged.

2.Check that the eeprom is properly connected. In case of doubt, it is recommended to try

with another eeprom to see whether or not the led of the transmitter logic lights up green.

3. In case the led lights up green with the new eeprom, we will have the eeprom broken,

and will have to replace it with a new one, copied from an eeprom and if it does not light up green,

substitute the transmitter logic following these steps:

4.6.- SUBSTITUTION OF LOGIC AND RADIO RECEIVER

1. Remove the key of the

contact lock to avoid breaking

its corresponding micro switch

on closing the button panel.

2. Remove the EEPROM from

the lower part with a

screwdriver.

3. Remove the battery and

unscrew the 7 screws of the

lower part of the button panel.

4. Separate, with caution, the upper

from the lower part, taking care with

the antenna that joins the two parts.

Once open, take out the antenna.

5. Unscrew the transmitting

logic from the lower part of the

button panel.

6. Disconnect, with caution, the

antenna connector from the

radio.

7. Remove the feed connector

which is located on the lower

part of the transmitting logic.

8. Substitute the transmitting logic

and follow the steps for assembling

the button panel in reverse. Position

the feed cables on the LE to avoid

crushing them when closing the

button panel.
