DESCRIPTION
The Tactical Technologies Inc. Model CTR-751/V series ("Joey") is a 1 channel 1/2 Watt VHF-FM synthesized voice
transmitter, combined with a solid state recorder.
The transmitter and recorder combination ("Transcorder") requires 9 volts DC for its power supply, utilizes an external
antenna for the transmitter, and a single microphone for both the transmitter and recorder operations. It can be optionally
equipped with a scramble for added security.
The CTR-751 series transmitter operating frequencies are programmed via an open serial port on an IBM compatible PC.
The transmitter's firmware is compatible with ANY vintage IBM compatible PC's communications program - such as
Microsoft's Hyperterminal. The recorder can use the same PC serial port. Proprietary software for recorder operations is
included. You can also program the transmitter in the CST-751/V direct from the panel of a Citation 20 Synthesized
Intelligence Receiver Recorder Kit!
Features of the Joey Solid State Recorder include: Easily concealable, Multiple MONO recordings, Very low power consumption, 2 Selectable sampling rates of 8 or 11 kHz, ability to download individual recordings, RS232 interface to standard PC
serial port, raw data download with audit trail identifiers and checksum information. The Joey recorder is also available with
either a 64Mbyte or 128Mbyte memory chip which respectively yields record times from 100 minutes to 440 minutes.
The supplied instructions are for the Window 95, 98, or XP operating systems.

TRANSCORDER OPERATION SETUP
1.) Connect the external antenna to the CTR-751 by inserting the
male end of the SMC type antenna connector on the transmitter to
the female connector end on the wire antenna. Twist the connector
clockwise to tighten (HAND TIGHT ONLY!).
2.) Connect the Microphone. Determine which of the two supplied
microphone configurations are best for your application: the long
leadwire microphone or the short/stubby microphone. Connect the
microphone by inserting the female end of the friction-locking 2 pin
connector on the microphone cable into the male connector found on
the CTR-751. This connector is keyed for proper installation. Push
the connectors firmly together.
3.) Connect the power lead to the transmitter. Connect the 9 VDC
battery lead by inserting the female end of the friction-locking 6 pin
connector on the power cable into the male connector found on the
CTR-751. This connector is keyed for proper installation. Push the
connectors firmly together.
4.) Any 9 VDC power supply (batteries, regulated supply, etc.) can be
applied to the CTR-751. When using disposable batteries, always use
either Alkaline or Lithium cells. Lithium cells are recommended for
longer operating life.
NOTE: DO NOT APPLY 12 VDC DIRECTLY TO THIS UNIT.
NOTE: THE CST-751 IS REVERSE POLARITY PROTECTED,
HOWEVER PLEASE BY SURE TO CONNECT THE + AND LEADS TO YOUR POWER SUPPLY CORRECTLY FOR PROPER
OPERATION OF THE TRANSMITTER. PAY PARTICULAR
ATTENTION TO THE MARKINGS ON SMALL BATTERIES.
WHEN USING THE FLYING LEAD CONNECTORS, THE
BLACK LEAD IS NEGATIVE AND THE RED OR WHITE
LEAD IS THE POSITIVE.
5.) Once power is applied to the CTR-751, the internal solid
state recording unit is ON and RECORDING. To turn the
recorder OFF, simply disconnect the power. Each time power is
applied to the unit, a new recording session begins.
6.) Turn ON the VHF transmitter. Locate the ON/OFF slide
switch. It is found between the antenna connector and the
microphone/power connectors on the top of the CTR-751. Turn
the transmitter ON by sliding this switch AWAY from the RED
DOT. The transmitter can be turned OFF by sliding the switch
TOWARDS the RED DOT.
NOTE: Once power is applied to the CTR-751, only the
transmitter can be turned ON or OFF. The recorder is always
ON.
7.) To turn the unit completely OFF, remove the power supply.

c.........Selects CLEAR transmission mode (for
units equipped with scrambling).
s..........Selects SCRAMBLE transmission mode (for
units equipped with scrambling).
Remember: All commands are lower case letters.
6.) Begin by VERIFYing the information about your transmitter.
Type a v.
Immediately upon your entering a "v", the program will report the unit's
ID (CTR-751/V) , and the frequency that is programmed into the current
channel. If your transmitter is equipped with scrambling capabilities, this
will be noted with an "S" after the model number (CTR-751/VS), and
whether the unit is in scrambled mode or clear mode (noted with a "c"
or an "s" before the frequency notation). The screen will look something
like this:
