Getting Started
The focus BRAIN XL system consists of 3 parts, the remote,
antenna and 19”-unit.
The remote unit
The remote has 16 keys and 1 slide switch. The slide switch is
for power on. However the power consumption is minimal, so
battery life is not really shortened, because depressing a key
activates the unit. The switch is mainly used as a safety
against unwanted key presses when the unit is in the pocket.
Battery replacement
Because of the often rough circumstances in which the unit
can be used, the battery compartment is closed with normal
M3 screws instead of clips. To replace the battery, remove the
two screws at the bottom, replace it with a fresh one and close
the lid with the same (4mm) screws. Be sure not to throw the
old battery in the normal dustbin, but remove it adequately.
Using alkaline batteries is recommended.

Key illumination
The keys on the unit are illuminated. While a key is pressed
the unit is transmitting, indicated by bright illumination of the
keys. When releasing the key the illumination stays on for a
period of time. The time(out) can be programmed on the
remote unit following these steps:
1) switch off the remote unit (slide switch on top)
2) press and hold FUNC, @, or ENTER
3) switch on the remote unit (slide switch)
4) wait until keys are blinking (
±
5 sec)
5) release the key
The time is now programmed to:

Active antenna
However the range indoors is specified up to 70m, steel tubing
(trusses/pipes) and building skeletons can influence this. To
overcome this problem the active antenna is separate from the
receiver unit. The connection in between is standard
microphone cable, up to 100m. The best position for the
antenna is in the middle above the front of the stage.
