un i t s, etc .) BEFORE pow e r in g up ampli f ie r s . Transient

voltages from powering up source equipment can damage

speakers if ampliers are already turned on. Make sure that

amplifier volumes are set to their minimum settings and

power up any system amplifiers L AST. It is recommended

that all system components be allowed to stabilize for several

seconds before any source signals are introduced or level

se t ting adjustments are made. Simil a r l y, when shutting

systems down, turn all amplifiers off first, before powering

down any other system components.

13. CABLES – Do not use shielded or microphone cables for

conne c tion bet ween amplifiers an d sp e a kers. Use only

approved speaker cables with proper connectors.

14. RI G GI NG – SU SPE NDI NG – MO UN TIN G – R ig g ing ,

TRANSMITTER / MICROPHONE (FIG.3)

Install the provided “AA” batteries in the microphone battery
compartment (Fig.4 / 5) by holding the main bar rel of the
microphone firmly while turning to unscrew the transmitter
section (the portion with the LCD display) and slide it open to
reveal the battery compartment in the middle section of the
mic.

Once the batteries are installed and the battery compartment
is closed and tightened, switch the microphone ON (the “1”
set ting on the small switch at the end of the microphone
barrel) to verify correct installation. The red LED on the mic
should illuminate and the LCD display on the mic will become
active.

Turn the microphone off (the ‘0’ switch setting at the end of the
microphone barrel) before proceeding.

AUDIO OUTPUT CONNECTIONS

Select the ‘LINE’ position of the ‘LEVEL’ switch when the
output of the receiver is connected to the line level input of

a mixer or amplier. Select the ‘MIC’ position of the ‘LEVEL’

switch when the output of the rec eiver is co nnected to a
microphone level input of a mixer. Distortion may occur if the
‘LEVEL’ switch is set to the wrong position. (Fig.8)

The ‘BALANCED OUTPUT’ should be used when the receiver
is going to be connected to either a microphone or line level,
balanced input of a mixer. (Fig.9)

Longer runs are less likely to cause problems with balanced
cables.

The ‘UNBA L ANCED OUTPUT’ should be used when the
receiver is going to be connected to a ¼” input jack of a mixer

or an amplier (usually line level) that uses a ¼” jack. Use the

appropriate setting on the ‘LEVEL’ switch on the rear panel
of the Contact 800T. Cable length for this type of connection
should be limited to less than 15 feet (5 meters). (Fig.10)

RECEIVER SETTINGS

Verify that the ‘VOLUME’ control setting is at its minimum (fully
counterclockwise).

With the microphone still turned OFF, Press and hold the
‘POWER’ button on the front panel of the receiver until the
LED display lights up.

Once the display is fully illuminated, press the ‘MENU’ button,
repeatedly, until the “G/CH” icon is highlighted. The display will
read the currently selected “GROUP” number and “CHANNEL”
number. These settings can be changed with the UP/DOWN
buttons. It is not necessary to change these settings in order
for the system to work, but they can be changed if any signal
interference is experienced. See the Appendix for Group /
Channel / Frequency assignments.

To change the ”GROUP” setting, press the “up” button (next
to the ‘VOLUME’ knob) repeatedly until the desired “GROUP”
number is displayed. There are 9 Groups available.

To change the ”CHANNEL” setting, press the “down” button
(next to the VO LUME knob) repeatedly until the de sired
“CHA NNEL” number is displayed. See the Ap p end i x for
Group/Channel correlations.

Once these settings are made, turn the microphone on and
press the ‘SYNC’ button and the receiver will automatically
synchronize with the microphone transmitter at the selected
Group/Channel frequency assignment. The synchronization
is suc c es sf u l when the “RF” level meter shows a signal
indication. The “AF” meter will respond to any sounds being
picked up by the microphone. Speaking into the mic should
show significant audio level indications on the “AF” meter.
Other indications on the receiver’s display will also indicate
“TX” (transmit) and one of the “A” or “B” antenna indicators will

LOCK / UNLOCK function:

Holding the ‘MENU’ button down for more than 3 seconds will
result in the word “LOCK” being displayed on the LCD panel.
This function stores the unit’s settings at the currently selected
configuration. When the unit is in “LOCK” mode holding the
‘MENU’ button for 3 seconds will toggle the function back to
the “UNLOCK” mode and parameters can be changed.

Display Modes:

Pressin g the ‘ M EN U’ butto n r e pe a te d l y wil l c h an g e the

-SQ (Squelch)

-VOL (Mute)

-NA ME (Name) will be highlighted in the display with each
press of the ‘MENU’ button

be highlighted showing which antenna has been automatically
selected for the strongest reception.

In accordance with the operating instructions of your mixer or
output device, adjust the gain controls and gradually increase
the ‘VOLUME’ knob on the Contact 800T receiver to achieve a
suitable level setting of the microphone signal.
