401X Quad Receiver
1. Powering the Receiver
Plug the
16V AC/DC ADAPTER (1)
provided into the
DC INPUT JACK (11)
on the back
of the receiver. Then plug the power supply into an AC outlet.
(Note: Any 16V DC source with 800mA capability can also be used.)
Turn
VOLUME CONTROL (6)
for all four channels counterclockwise to mimimum located
on the front of the receiver. Once the receiver is connected to a power source, press the
POWER SWITCH (3)
to ON position. The
POWER ON LED (4)
indicator will light up.
The
TX LED INDICATOR (7)
on the front panel of the receiver will not light up until one
or more of the four channels is receiving a signal from your system’s transmitter.
2. Antennas
The
ANTENNAS (2)
assembly consists of two antennas. Connect antennas into the
ANTENNA JACKS (5)
on the front of the receiver. Extend the antennas fully to obtain
maximum range. Position
ANTENNAS (2)
at 45 degrees from the horizontal; 90 degrees
from each other. For maximum range, it is always best to maintain a line of sight (no
obstructions) between the receiver antennas and the transmitter whenever possible.
3. Mute (Squelch) Adjustment
In normal operation, the
MUTE CONTROL (9)
should be set fully counterclockwise to the
factory preset minimum RF level of 1µV for maximum sensitivity. Doing so sets each
receiver for maximum range. However, in areas of high RF activity, the mute (or squelch, as
it is sometimes called) may need to be adjusted to compensate for the adverse conditions in a
particular location. If, with the transmitter off, its corresponding LED on the receiver front
panel flickers or stays on, the
MUTE CONTROL (9)
should be turned clockwise until the
LED extinguishes. For each of the four channels, when the Mute is properly adjusted, the
corresponding LED will light only when the system’s transmitter is turned on. Turning the
MUTE CONTROL (9)
too far clockwise will result in reduced range, but yield a quieter
signal during dropouts or at the end of the operating distance range.
