Technical precautions
• Operating temperature: Entrance Station: -10 °C to 60 °C
(14 °F to 140 °F)
Residential Station: 0 °C to 40 °C
(32 °F to 104 °F)
Security Guard Station:0 °C to 40 °C
(32 °F to 104 °F)
Control Unit: 0 °C to 40 °C
(32 °F to 104 °F)
• 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 (GFH) 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 properly,
request a qualified technician for repairs.
