INFO: The laser with antenna symbol in the display is indication for the connection
status of receiver and laser. When an automatic function with laser and receiver fails,
the missing symbol is a rst indication of a root cause. When the symbol is missing
this can be the reason:
-The laser is o. Check the laser, it may have shut o for some reason. Turn it on and
check if the symbols will come back after a few seconds.
The laser is not paired with the receiver. Maybe this laser was paired with the receiver
before but for some reason the pairing has been lost. Start the pairing process
described in this chapter.
22 Remote Control RC1402
22.1 Powering the RC1402
a) Open the battery door using a coin or similar pry device to release the battery door
tab on the RC1402. Alkaline batteries are typically used. User provided rechargeable
batteries can be used but need to be charged externally.
b) Insert two AA batteries noting the plus (+) and minus (-) diagrams inside the
battery housing.
c) Close the battery door. Push down until it “clicks” into the locked position.
22.2 Turning On/O the radio remote control RC1402
The radio remote control is a hand-held device that allows you to send operational
commands to the laser from a distance.
Press the power button to turn on the radio remote control.
To turn o the radio remote control, press and hold the power button for two seconds.
When the remote control is initially turned on, the standard display (model number
and software version) appear for the rst three seconds (see pic 31), then the RC1402
LCD shows the actual laser function. This standard display is also shown when the
RC1402 is out of operating range or is not paired with the laser or the paired laser is
not switched on.

With every button press, the LCD backlight is activated and turns o automatically
if no button is pressed for 8 seconds or 60 seconds, depending on the settings. See
chapter 17.5 on how to change the settings for the backlight.
Note: Five minutes after the last button press, the remote control turns o
automatically to save battery.
22.3 Pairing the RC1402 remote control with the laser
WHY: The communication between RC1402 remote control and the GL1425C laser
is based on a radio communication path. This enables a unique communication path
that ensures only the paired laser will be controlled by the paired remote control.
WHAT: When the pairing has been lost for some reason, when the radio channel has
been changed or when the remote has been added or replaced, the pairing needs to
be reestablished.
