Room channel number
For allocation of different room (channel) numbers press the keys REGISTER and LS INTERN of the Radio
Transceiver unit DSpark simultaneously. This will enter the configuration mode.
Figure 12
DSpark confirms this mode by blinking two times of all 4 LEDs (RE HIGH POWER + PRIO +
LS INTERN) . The current room channel number is displayed.
The pattern of the LEDs is shown in the table below:

Now the user can specify the new logical radio channel number by setting the LEDs with the corresponding
buttons “On” or “Off”. It is insignificant which LEDs are switched, or in what order this happens. Only the
number of LEDs lucent is relevant as input for the new radio channel number.
Examples for valid input of radio system number 2:
logical room

REGISTER
LED HIGH

2 on on off off
2 off off

2 off on off on
2 off on on off
Five seconds after pressing any button the configuration mode is finished. This is indicated by blinking two
times of all 4 LEDs (RE HIGH POWER + PRIO + LS INTERN). The new radio channel number is
now saved and will be used until this setting is changed again.
Also the primary status of the LEDs and the function of the buttons are restored. The new settings are
immediately effective; there is no need to switch DSpark on and off.
If no changes are made in configuration modus the current setting persists when leaving the configuration.
Therefore this procedure can also be used to show the current setting of the room channel number.
