Girard Systems awnings may be operated in light wind and rain
conditions. When periods of heavy rain and or high wind are expected
the awning must be closed. Never leave the awning open and
unattended.
Damage caused by wind and rain is not covered by warranty.
All awnings must be closed prior to moving the vehicle for any reason.
As an extra safety precaution a visual check that every awning is fully
closed is required.
Damage caused by failure to comply with these instructions is
not covered by warranty.
Before using your awning, ensure that the area into which the awning
will be deployed is free of obstructions (Trees, walls, pillars, posts,
other vehicles etc.)
Damage caused by collisions with any of the above or similar is
not covered by warranty.
Before using your awning make sure that all of your electrical circuits
are operating correctly. Recreational Vehicles can generate AC power
from three separate sources. The electrical system transfer switch in
your vehicle will select power for the awning as follows:
Shore Power –if connected;
Generator Power –if the generator is running;
Inverter Power –batteries must be charged for inverter operation.
Girard Systems awnings are supplied with an electric motor appropriate to the
product.

THE G–LINK SYSTEM
The G-Link motors and control modules provided by Girard Systems communicate by
use of RF signals on a frequency of 433.92 MHZ. This eliminates the need for wiring
and the drilling of holes in the vehicle. These components must be electronically
matched, programmed or paired before use. This is usually done at the Girard Systems
factory. Should the need arise for the user to pair a device with the motor controller
they must refer to the appropriate manual for the devices applicable to their particular
installation.

PRODUCT DESCRIPTION
Fig.1
This module is designed to control a single Standard 110v AC Motors UP to 8 Amps. It
can be remotely operated with any paired G-Link handset or wall switch. The controller
will receive signals from a distance of more than 500ft in open air and more than 100ft
in the presence of obstructions. The RF transmission frequency is 433.92MHZ.
The awning may be operated from the GC274C using the FWD/STOP/REV buttons (see
figure 1.). The direction of travel of the motor can be reversed without the need of
changing the wiring by pressing the Left and Right buttons of the module
simultaneously for least 6 seconds.
The GC274C may be programmed with up to 20 compatible remote modules. If an
additional module is programmed it will replace the most recently programmed module.
The previous 19 modules will remain unchanged.
The GC274C operates in Continuous mode.
Continuous mode means that a single press of the button on the module or the Remote
handset will cause the Awning to move in the chosen direction until the limit switch is
actuated, unless the Stop button is pressed.
