Before Using the TUN-3.7 —Continued
Notes:
• If the remote controller doesn’t work reliably, try
replacing the batteries.
• Don’t mix new and old batteries or different types of
batteries.
• If you intend not to use the remote controller for a
long time, remove the batteries to prevent damage
from leakage and corrosion.
• Flat batteries should be removed as soon as possible
to prevent damage from leakage and corrosion.
When using the remote controller, point it toward the
TUN-3.7’s remote control sensor, as shown below.
Notes:
• The remote controller may not work reliably if the
TUN-3.7 is subjected to bright light, such as direct
sunlight or inverter-type fluorescent lights. Keep this
in mind when installing.
• If another remote controller of the same type is used
in the same room, or the TUN-3.7 is installed close to
equipment that uses infrared rays, the remote control-
ler may not work reliably.
• Don’t put anything, such as a book, on the remote
controller because the buttons may be pressed inad-
vertently, thereby draining the batteries.
• The remote controller may not work reliably if the
TUN-3.7 is installed in a rack behind colored glass
doors. Keep this in mind when installing.
• The remote controller will not work if there’s an
obstacle between it and the TUN-3.7’s remote control
sensor.
