Changing Channels - GN Resound LYNX BL-95 Manuel D'utilisation

ENGLISH

Changing channels

The transmitters in the Lynx system transmit the signal wirelessly to the flash alert. They can transmit
on a total of 16 different channels (0-9, A-F). The flash alert and all transmitters must be set to the same
channel so that they can communicate. They are pre-set to channel 9, and then operate together without
alteration. In some cases, it may be necessary to change the channel setting. If two or more users live
near one another, the alarms can interfere. This can be rectified by changing the channel settings so that
they are different for everyone. Any channel can be selected except Channel 0. (Channel 0 is reserved for
a common alert such as a fire alarm.)
If you need to change the channel on the flash alert, proceed as follows: Move the white lamp cover
upwards. You can see where the microswitches are located from the diagram on page 3. Set the switches
as shown in the table below. To change channels on the receiver, see user manual.

Troubleshooting
1. Check that the connection is correct and that all transmitters and receivers in the system are set to
the same channel. If the flash alert is still not working, move on to the next steps.
2. Set the flash alert to test mode: Move the white lamp cover upwards in order to access the channel
selector. Set microswitch 3 to ON. The yellow LED starts to flash.
3. Check interference from other equipment: The red LED now indicates whether there are other signals
in the surrounding area which are transmitting on the same frequency as the flash alert. If the red
LED does not light up or flashes 1-2 times per second it is OK. If, however, it stays on or flashes
rapidly, this is a sign of interference.
Action: Move the flash alert to another location in the room.
4. Check interference from another transmitter: If the yellow LED is constantly on and the red and orange
LEDs are flashing, this means that the flash alert is receiving interference from another transmitter in
the vicinity which is transmitting on the same channel.
Action: Change the channel of the transmitters and receivers in the system (see "Changing channels"
above).
5. Quit test mode: Set microswitch 3 to OFF. Then take the mains adapter out and put it in again to
prepare the flash alert for normal use. Then test the system.
