channel, VHF-FM synthesized voice transmitter combined with a state

of the art solid-state digital recorder, specifically designed for law

enforcement use. The concise product description of the

J1W

would be

TRANSCORDER

The unit utilizes an external antenna for the transmitter and a single

microphone for both the transmitter and recorder operations. The

J1W

can be equipped with an optional scrambler for added transmitter

security.

The

Joey1W

, whilst utilizing an onboard hardware compander, derives

unprecedented audio quality from its ability to capture sounds at user

definable settings. The

Table 1, Joey1W Standard Packing List

1.3 Using the J1W Transcorder

The

J1W

is designed to be used,

 operationally in a stand alone configuration, or

 in conjunction with its USB cable and a personal computer

for configuration, downloading and replay of stored audio, or

 connected to a personal computer, TTI Citation Receiver, or

TTI PTX-100 for Transmitter Only Frequency Programming.

Before using the

J1R

in an operational environment, it should first be

run in PC Mode and the recorder configured using the accompanying

Joey

software. The Transmitter operating frequency must be

programmed separately.

NOTE: Transmitter must be switched OFF while operating in PC Mode.

1.4 PC Mode – Recorder Operation

Install the

Joey

software and USB device drivers.

Using the USB cable supplied, connect the

J1R

to the computer and

configure the unit to the desired operational parameters by running the

Joey

software. Make sure the Transmitter ON/OFF switch is in the OFF

position.

To connect the USB cable to the

Joey1W

, align the arrow and yellow

dot on the USB Cable 6 pin connector with the yellow dot 6 pin

connector of the

J1W

unit. If you attempt to install the cable upside

down, you will damage the

Joey1W

Make sure that the connector makes contact head on with the

J1W

ensuring no twist in the connection which may result in connector

damage. Removal of cables also requires the connectors to come off

without much twist, so that damage does not occur to the unit.

When using the USB cable, the

Joey1W’s

recorder draws power

directly from the computer through the cable.

After you are finished configuring the

Joey1W

, disconnect the

recorder from the USB cable. The recorder will remember it’s

configuration parameters and will operate according to those

parameters the next time power is applied.

1.5 Stand Alone Mode

Once the recorder is configured using the

Joey

program and

transmitter frequency has been programmed using a Citation Receiver,

Personal Computer, or PTX-100 programmer. The transmitter and

recorder will remember and use the current configuration each and

every time power is applied to the unit.

1.5.1 Making the Connections

For an operation, you must decide how you want to configure your

J1R

1. No matter what, you must connect the antenna.

2. External tethered or internal microphone?

3. Is there a need for the optional, tethered remote ON/OFF switch?

See the diagram below for connector placement on the

J1W

Figure 2, J1W Connections

A: External Microphone Connector

B: Transmitter ON/OFF Switch

C. Antenna Connector

D: MASTER On/Off Switch

E: 6 Pin connector for recorder programming, or external

remote on/off switch.

Antenna

Connect the external antenna to the

J1W

by inserting the male end of

the SMC type antenna connector on the device to the female

connector end on the wire antenna. Twist the connector clockwise to

tighten, HAND TIGHT ONLY!

Microphone

Determine which of the two microphone configurations are best for

your application: the long tethered remote microphone or the internal

microphone.

If you choose the internal microphone, you do not need to do

anything. If you choose the external microphone, connect the external

microphone by inserting the plug male end of the mini connector on

the microphone cable into the female jack found on the

J1W

. Push the

connectors firmly together. Twist the plug clockwise slightly to lock

the connector in place. HAND TIGHT ONLY! Switching between

the internal and external microphones is automatic and accomplished

when the external microphone plug is inserted into (or removed from)

the microphone jack on the J1W.

Power

IMPORTANT: Before applying power to the

J1W

ensure that:

a) The Transmitter On/Off Switch is OFF, or

b) An antenna is connected to the

J1W.

Never apply power to the

J1W

without an antenna connected.

The J1W is powered by two 9 volt batteries which will operate both

the transmitter and the recorder for up to 3 hours.

1.5.2 Microphone and Antenna Placement

As a general rule the external microphone should be as close as

possible to mouth level. Sound waves travel in straight lines and the

placement should reduce obvious obstructions. If a microphone is to

be placed behind a surface, which is not porous, a small pin hole

should be placed in the surface opposite the microphones diaphragm.

Ensure that any material will not rub against the surface of the

microphone.

For maximum efficiency, the

J1W

antenna should be kept

vertical whenever possible. Placing the antenna on a metal

object may result in quite poor performance of the

J1W

’s

transmitter. The antenna should not be wrapped around the

J1W

, nor should it be coiled or bunched in a ball. The antenna

used for this transmitter must not be collocated or operating in

conjunction with any other antenna or transmitter. The antenna

must be installed to provide a separation distance of at least 20 cm

from all persons.

1.5.3 Operational Mode

When power is applied to the

J1W

via the master power switch, the

unit will wait for approximately three seconds, and then start to

record using its current configuration.

Note: The exception to this is if the unit has been previously

configured for timer mode. (See Error! Reference source not

found. Error! Reference source not found.)

Once the unit is recording, the transmitter will come on instantly when

the Transmitter Power Switch is turned ON (towards the red dot).

Removing power stops the recording and the RF transmissions.

Subsequent recordings and resumption of transmissions may be made

by re-applying power to the recorder. This is repeatable up until the

unit becomes full and cannot record any more audio. The transmitter

will still operate, even if the recorder is full..

When the operation is completed or the recorder becomes full, it

should be downloaded using the

Joey

program. The recorder does not

require power to retain its recordings and downloading can happen at

any time subsequent to a recording being made.

Noteworthy Operational Considerations

Before ANY use of the

Joey1W

1. Verify the TRANSMITTER is functioning correctly by

checking its transmission with a good quality receiver

programmed to the correct frequency.

2. Verify the RECORDER portion by operating the

J1W

in PC

Mode and making a test recording.

3. ALWAYS use a fully charged battery at the start of any operation.

4. PRACTICE with this piece of equipment prior to official use.

1.6 Timer Mode

When configured to timer mode, the

J1W

’s recorder will sleep until

the next preset start time has been reached. After all timers have

expired, the

J1W

’s recorder remains in sleep mode until a power reset

returns it to normal operation. If all start times have expired prior to

power being applied, the

J1W

’s recorder operates as if no timers had

been set.

1.7 Recording Quality

The

Joey1W

’s

audio front end and data storage algorithms are

designed to provide the user with a range of quality options ranging

from direct storage of the 8 bit samples (Linear Pulse Code

Modulation, LPCM) to Adaptive Differential Pulse Code Modulation

(ADPCM) for the 4 bit modes.

Sampling Speed (kHz) Typical Bandwidth (Hz)

8 3200

11 4700

Table 2, Typical Joey1W Recorder Audio Bandwidths

1.8 Recording Times

The

Joey1W

will yield the following recording times based on its

recording profile,

Quality Bits 64 MB 128 MB 256 MB 512 MB

8 bit – LPCM 1.7 hrs 3.3 hrs 6.6 hrs 13.2 hrs

11 kHz

Mono 4 bit – ADPCM 3.3 hrs 6.6 hrs 13.2 hrs 26.4 hrs

8 bit – LPCM 2.3 hrs 4.6 hrs 9.1 hrs 18.2 hrs

8 kHz

Mono 4 bit – ADPCM 4.6 hrs 9.1 hrs 18.2 hrs 36.4 hrs

Table 3, Recording Times

The new 1024 MB J1W will double the times found in the chart for

the 512 MB unit.

The total recording time is not diminished if more than one recording

is made on the

Joey1W

to make up the total.

1.9 Power Considerations

The J1W will operate continuously with two new 9volt batteries and

both the recorder operating and the transmitter operating for up to 3

hours.

The following table is indicative of the typical recording times

available using some standard battery configurations.

hours must be reduced.

1.10 Concealment and Tactical Issues

Concealment and tactical issues surrounding the use of the

Joey1W

are beyond the scope of this guide.

1.10.1 Range of the J1W Transmitter

It is impossible to state absolutes about how far an RF transmitter like

the

J1W

will transmit. Many variables affect the range of a device

including buildings, trees, weather, construction materials,

installation, etc.

All things being perfect (meaning transmissions are outdoors over flat

terrain with no obstructions), a

Joey1W

should be able to easily

transmit over a mile. You should expect less distance than that

however, in a real world operation.

One of the most important variables, and one that the operator can

actually control, is the placement of the receiver and the receiving

antenna. A good rule to follow is the higher the antenna placement, the

better chance you have of quality reception. This alone will increase your

operating range. Just having the

J1W

in an ideal location is not enough.
