SC2 HANDHELD TRANSMITTER FEATURES AND CONTROLS
(FIGURE 3)
1. Grille: Protects the microphone element and helps minimize breath
and wind noise. Various models have different grille styles.
2. Battery Fuel Gauge: An array of LEDs that light to indicate level of
battery life remaining when battery check switch is pressed. The
transmitter must be turned on in order for the fuel gauge to function.
3. Battery Check Switch: Activates the battery fuel gauge. Allows user
to check amount of battery life remaining at any time while the
transmitter power is on.
4. Power ON/OFF Switch: Turns transmitter power on and off. When the
receiver tone key squelch feature is enabled, this switch also functions
as a system “mute” switch, allowing the receiver to reject unwanted
signals when the transmitter is turned off.
5. Power ON LED: Green indicator lights when power on/off switch is
turned on and a good battery is installed. If this LED is not illuminated,
the transmitter is not operational.
6. Audio Gain Control: Provides audio level adjustment to accommodate
different sound sources. This control is accessed by removing the
battery cover. A small screwdriver located behind the SC4 control
compartment door is supplied to make adjustments.
7. Frequency Selector Switch: Provides system frequency agility by
allowing user to select from eight different operating frequencies at 200
kHz intervals. It is factory pre–set to position #4 and is identical to the
frequency selector switch on the SC4 receiver.
8. Battery Cover: Unscrews to provide access to the battery, audio gain
control and frequency selector switch.
SYSTEM SETUP AND INSTALLATION
RECEIVER CONNECTIONS
1. Connect the supplied AC adapter to the POWER jack on the rear panel.
2. Plug the adapter into a power source (120V, 60 Hz power for the PS40;
230V, 50 Hz power for the PS40E).
3. Attach the supplied 1/4–wave antennas to the antenna connectors on
the back panel. For best performance, point the tips away from each
other, at an angle 45°from vertical. If the receiver is rack-mounted, both
antennas must extend above the rack cabinet or be remotely located.
NOTE: For improved diversity performance, use 1/2–wave antennas and
WA420 Extension Cable Kits. Install one or both antennas at a remote
location within sight of the receiver.
4. Connect the SC4 output to the mixer or amplifier input, using a standard
audio cable with a female XLR connector or a 1/4-inch phone plug on
one end.
