THE 1200URX/Si
The 1200URX/Si receiver is specially designed to work with specific
Panasonic “Slot-In” or Ikegami “Uni-Slot” cameras. Once mounted in
the camera, the DB-25 connector on the bottom provides the receiver
with power directly from the camera’s power supply (battery) while
delivering audio directly to the camera’s audio input. Items

The MODE Switch
[

]
performs 1 of 5 functions.
Initial MODE display:
The initial MODE shows the receiving band shown as Group, Channel
and Frequency. If there is no action taken with the MODE switch for 4
seconds the display will return to the Initial Display. Pressing the MODE
switch for one second while showing the Initial Display will cause the
currently set frequency to be displayed.
Mode#1 (GR):
From the Initial Display , quickly pressing the MODE Switch once dis-
plays the Group Display. Pressing the UP or Down buttons will change
the Group Number . There are 7 Groups, 6 of which have the best
selection of frequency combinations when using multiple systems.
Group 0 allows for choosing any channel/frequency. The last set Group
is memorized when the receiver is turned off. The chart on page 3
shows the Group vs Frequency combinations.

1200URX/Si Top panel display and operation (continued)
As the RF signal from the transmitter gets stronger (or weaker) the
number of illuminated LCD segments in the display will change - with 3
segments being the maximum and best. Similarly, the AF (audio level)
segments will light from 1 to 3 segments as the audio gets stronger or
weaker. In this case the best level is achieved as the display shows
between 2 and 3 segments. If all 3 segments stay illuminated for a
continued period of time it is likely that you are over-driving the
receiver’s input and you should reduce the transmitting level by either
moving the microphone further away from the sound source or reduc-
ing the input gain on the transmitter.

Mode#2 (CH):
To change the channel/frequency within the selected group, press the
MODE switch a 2nd time. “CH” will be displayed. Using either the UP
or DOWN button [
l
] the desired receiving channel/frequency
combination can be set (the chart on page 3 shows the relationship).
Tapping the button steps the channel/frequency number one at a time
while pressing and holding moves through the combinations rapidly .
There are 188 different channel/frequency combinations to chose from
(Group “0” allows you to select all of the combinations). Once the
desired channel/frequency has been determined set both the transmitter
and receiver to match. When the receiver is turned OFF the last channel/
frequency chosen is stored in memory .
Mode#3 (SQ):
To change the squelch level, press the mode switch for a third time.
SQ will show in the display . There are 3 settings to choose from:
on on = RF mute ON - Tone mute ON (default)
on off = RF mute ON - Tone mute OFF
off off = RF mute OFF - Tone mute OFF
You can cycle through these with the UP/DOWN buttons. The Squelch
returns to the default when the receiver is turned OFF .
Mode#4 (SQ Level):
There are four levels of Squelch to choose from:
0 = Default
3 = 3dB (RF) increase to the default
-6 = 6dB (RF) decrease to the default
-3 = 6dB (RF) decrease to the default
You can cycle through these with the UP/DOWN buttons.
See the discussion at the bottom of page 2 and the top of page 4 for
information concerning the other parts of the display .
