Setting up the System
1. Make sure that all units are installed and wired properly. Turn
on the power switch to GH-BC. When the system includes GHNS, program the resident information (names and room
numbers) in advance. (For details, see 4-2)
2. Loosen the base screw and open and remove the front panel.
3. Set the system to program mode.
• Lift up the rubber cap.
• Press the program switch once. Use any long thin tool, such as
a fine screwdriver.
• The In-Use LED will blink for approximately 15 seconds for
entrance stations with GH-SW and between approximately 6 to
15 seconds for entrance stations with GH-NS.
4. Once the In-Use LED is lit solid, press the talk button of the
first residential station. The corresponding communication
channel will be established.
5. For GH-SW, press the (corresponding) call button and release
quickly. (Do not press the button longer than 1 second) For GH-NS,
display the assigned room No. and press the call button
(bell symbol). (Do not press the button longer than 1 second)
An electronic beep will be emitted once.
6. Press the talk button to end. Repeat these steps and program all
residential stations.
If there is a second residential station installed in a single apartment,
program the residential station following the same method detailed
in steps 4 through 6. An electronic beep will be emitted twice. An
electronic sound will be emitted three times for a third residential
station and four times for a fourth residential station.
7. Correcting or changing the settings
• Press and hold down the call button of GH-SW or GH-NS until
you hear a continuous beep. For GH-NS, display the room you
want to correct and reprogram all the residential stations in the
single apartment (following steps 4 and following).
8. Ending programming
• Push the GH-DA program switch. The In-Use LED will go off.
• Replace the cap.
9. Checking the programming
• Pressing the program switch for 5 seconds or more will light up
the In-Use LED.
• In the case of GH-SW, an electronic beep will be emitted once
when the programming was successful. If the programming was
unsuccessful, an alarm beep will be emitted.
• For GH-NS, use the arrow keys or 10-key to select the room
and press the call button. An electronic sound will be emitted
once when the programming was successful. If the
programming was unsuccessful, an alarm sound will be emitted.
• Press the programming switch to end the check.
If power supply is interrupted during programming, the
programmed information might be lost. In such cases, retry
the programming again from the beginning.
NOTES: 1. Setting up the light button (GH-SW) In Step 3, press the
call button of the assigned GH-SW while the In-Use
LED is blinking (within 15 seconds in program mode),
the light button will be set up. (The assigned call button
cannot be used as the residential call button
simultaneously.) An electronic beep will be emitted once.
2. If you attempt to setup a fifth residential station when four
residential stations have already been established, an alarm
beep will be emitted. To cancel the communication link,
display the assigned name and press the call button for at
least 3 seconds. A continuous beep will be emitted to verify
the communication link has been cleared.

Programming (GH-NS)
a. Programming with a PC
• You can use a PC to enter data and write in or change resident
names.
• Use the connection cable that comes with GH-NS to connect
your PC to GH-NS.
• In your PC, install the setup tool program from the CD that
comes with the GH-BC.
For information on how to use the setup tool, see the text (.txt)
file that is installed in the same folder as the setup tool (.exe).
b. Programming with GH-NS and GH-10K
• Confirm that "Welcome" is shown on the Display, indicating
that the system is in standby mode.
You can change the "Welcome" text.
• First, set the system to program mode. (For details, see above.)
Before you begin programming, we recommend that you
register a new exclusive ID code for yourself so that the
system is not accessed by others. (For details, see 4-3)
If you have forgotten your ID code, set the switch (#1) to ON
for approximately 2 seconds. The ID code will be reset to the
default setting of " 1111".

TECHNICAL PRECAUTIONS
Technical precautions
• Operating temperature: Entrance Station: -10 - 60 C
Residential Station: 0 - 40 C
Security Guard Station: 0 - 40 C
Control Unit: 0 - 40 C
• Mounting location:
Do not install the entrance station in a
place where there would be a bright
light behind a visitor (or where there
would be a bright background) or in a
place where the camera lens would be
directly exposed to sunlight or a bright
light.
• Rain hood (option):
Although the entrance station is
weather resistant, it is recommended
that it not be directly exposed to
weather conditions. The rain hood (GF-H)
can be installed to protect the
entrance station from rainfall.
• Post-replacement setup: After all wiring is completed and the
residential station has been replaced,
turn off the power to GH-BC
temporarily and then turn it back on.
Next, reprogram the relevant
residential station.
• Operation:
When an entrance station is calling a
residential station, the call tone from
the doorbell button will not sound.
• Cleaning:
Clean the units with a soft cloth
dampened with a neutral household
cleanser. Never use an abrasive
cleanser or cloth.
• Repair requests:
When units do not operate normally,
request repairs from a qualified
technician.
