3. PREPARATION FOR INSTALLATION
h About 3 hours are required for the installation.
h Before you begin, coordinate the time of installation with the store owner/manager to
minimize disruption of business.
h Be certain electrical power is available.
h Be certain some type of compatible vehicle detector loop or other vehicle detector system has
already been installed in the drive-thru lane(s).
3.1 Tools Required
h Phillips (cross-point) screwdriver, size #2
h Standard (slotted) screwdriver, ⅛ inch (3.2 mm)
h Power drill and drill-bit set
h Fish tape, 100 feet (30 meters)
h Wire cutter/stripper
h Soldering iron
h Rosin-core solder
h Electrical tape
3.2 Interference Prevention
CAUTION: Interference may occur if the headset system is not properly installed.
The following types of interference could occur if precautions are not taken during installation. Read
this section carefully before proceeding.
3.2.1 Electrical Interference
Electrical faults in appliances and other electrical equipment can cause interference such as static,
hum, crackling, buzzing and zip sounds in the headset when the system is active. Interference caused
by electrical faults in lighting systems might not be noticed immediately, since most lighting systems
are controlled by a timer or light sensing device.
Faulty Wiring or Components:
Faulty components or electrical wiring in menu boards or speaker posts can cause symptoms identical
to those caused by AM interference. Remove power to the menu board or speaker post at the circuit
breaker until the electrical system can be repaired.
Improper Earth Grounds:
Improper earth grounds in the building can cause random buzzing and zip sounds in the headset when
operating in either channel A or B. Placing a surge protector between the base station AC adapter and
the electrical outlet can eliminate the problem.
In the event of an electrical power outage
If you experience problems with your HME equipment after the electricity
returns, unplug the equipment, wait 15 seconds and then plug it back in.
3.3 Hop Band: Radio Frequency Interference
Radio Frequency Interference caused by Wi-Fi routers and Access Points
Most Wi-Fi access points allow the administrator to set the channel and bandwidth for the system. Some
systems employ an ‘Auto’ mode, in which the Wi-Fi access point will automatically select the channel.
With Wi-Fi access points, it is sometimes advantageous to manually select a channel number to keep the
Wi-Fi transmission at a xed location. Common Wi-Fi channels used are 1 and 11.
