4.) Select the operation for the DSP switch (DIGITAL SIGNAL PROCESSOR FILTER - or the

Adaptive Digital Audio Filter)

This switch toggles the Citation's Digital Signal Processor Filter operation between three settings:

OFF, 14dB of digital filtering (max. filtering), and 8dB of digital filtering (minimal filtering).

Each time you press the switch, the LED indicator cycles color from OFF to RED to YELLOW.

When the LED is OFF, the filter is off. When the LED is RED, the filter is in the MINIMAL

FILTERING or 8dB setting. When the LED is YELLOW, the filter is in the MAXIMUM

FILTERING or 14 dB setting.

This filter can eliminate unwanted backgrounds noise. By using its internal algorithms,

the filter detects repeating noises such as receiver white noise, background rumble, etc., and filters

them out. The filter processes are NOT recorded by the on-board recorder, however. This retains

the integrity of the original reception from the receiver. The filter can be used 'live' during receiver

reception, as well as during playback of a prerecorded tape. You should experiment with this filter

to see what settings you should use to best fulfill your needs.

5.) Adjust the VOLUME control to the center position. Alter the volume to operator preference

once transmission has begun.

6.) Adjust the SQUELCH control fully to the counter-clockwise position. The noise you hear

coming from the audio system is called "White Noise". Turn the squelch control clockwise until

this white noise just disappears and the audio system is quiet. This is called the "Critical Squelch"

point. Critical Squelch is the optimum point of squelch for the system. Squelch may then be

adjusted to the operators preference at any time by turning the control clockwise to increase, or

counter-clockwise to decrease the amount of squelch in the circuit.

7.) If receiving transmissions from a scrambled TACTICAL TECHNOLOGIES INC transmitter or

repeater, set the SCR switch to ON (corresponding LED is ON). If the transmission is not

scrambled, set this switch to OFF (LED is OFF).

8.) The Citation will now receive transmissions from your transmitter. Audio will be heard

through the internal speaker.

9.) If you prefer private listening, insert a male stereo phone jack from any stereo headphones or

earphone into the EAR jack. This will disconnect the external speaker. The volume control will

now control the audio level in your headphones.

RECORDING TRANSMISSIONS

1.) Complete the steps outlined above for Receiving Transmissions.

2.) Press the STOP/EJECT button to open the CASSETTE TAPE COMPARTMENT. Insert a

BULK ERASED blank cassette into the slot on the compartment lid so that the open edge of the

cassette faces up and the full reel of tape is toward the left. Close the cassette compartment lid.

NOTE: TACTICAL TECHNOLOGIES INC. RECOMMENDS USING A BULK ERASED TAPE ANY

TIME THE RECEIVER/RECORDING SYSTEM IS IN OPERATION. A BULK ERASED TAPE

ASSURES THAT THE CASSETTE BEING USED IN THE OPERATION IS CLEAN AND FREE OF

ANY UNWANTED PREVIOUSLY RECORDED MATERIAL, AND WILL ASSIST IN ACHIEVING

THE OPTIMUM QUALITY IN RECORDING OPERATIONS. RECORDING QUALITY WILL VARY

HOWEVER DUE TO TRANSMISSION AND RECEPTION CONDITIONS.
