* Use Code "44" to program No Tone for systems without

a Coded Squelch Interference Eliminator feature. Refer

to the text at right.

TABLE 2: QUIET CALL TONE CODES

*44

What is Quiet Call Sub Audible Coded Squelch? The

Quick Talk radio transmitter is compatible with two

standard communications industry sub-audible signaling

formats: QC® (Quiet Call Interference Eliminator), and

DQC

(Digital Quiet Call Interference Eliminator). Both

Quiet Call formats unlock receivers programmed to

require these codes -- they screen out interference from

other radio systems operating on your same frequency.

QC® QC is Ritron’s trade name for what the

communications industry calls sub-audible

(below the range of human hearing) tone squelch,

or CTCSS (Continuous Tone Coded Sub-audible

Squelch). Other radio manufacturers use different

trade-names for essentially the same system.

You may program a specific QC code into your

Quick Talk to transmit with the voice messages,

which will "unlock" the receivers in your radio

system.

DQC

DQC is Ritron’s digital coded squelch which

works basically the same as QC, except a digital

code is transmitted with voice messages.

Do I need to program my Quick Talk with a Quiet Call

Code? Your radio system may or may not use coded

squelch signaling. If you have programmed the Quick Talk

to match your radio frequency, and your radios are not

receiving Quick Talk transmissions unless the "monitor"

or "test" button is pressed, your system is probably using

Coded Squelch. Refer to your radio manual, or contact

your radio dealer or Ritron if you are unsure about this

issue.

If your Quick Talk was previously programmed with a QC or

DCC code and you need to remove it, follow the procedure

below, using No Tone code, "44", shown in Table 2, at left.

To Program a QC Sub-audible Squelch Code:

a. Determine the Quiet Call code tone that your radio

system uses. If your system uses Digital Quiet

Call, go to the next page.

b. Select the desired Tone Code from Table 2 at left;

enter the code below.

NOTE:

If your radio system does not use coded

squelch, program No Tone, code "44".

c. Pick up the telephone receiver and listen for the

acknowledge tone.

d. Dial "21", then the 2-digit QC Code you have

selected.

For example, if your Quiet Call frequency is

103.5 Hz (Code 13), dial: "2113".

Quick Talk will respond with a confirmation tone.

e. You may either hang up or continue programming

additional features.

PROGRAMMING QUIET CALL

SUB-AUDIBLE SQUELCH

INTERFERENCE ELIMINATOR

RECORD your frequency and squelch code—

Frequency: ______________________________ ;

QC or DQC Code: __________________________

TO SET TRANSMIT FREQUENCIES:

Set standard (tabled) transmit frequencies following the

instructions on page 6.

See the box below. Set other frequencies as follows:

a. Pick up the telephone receiver and listen for the

acknowledge tone.

b. Dial "12", followed by the first six digits of the

frequency setting.

UHF UNITS: Frequency step size is 12.5 kHz;

the selection range is 450.000 to 469.9875 MHz.

VHF UNITS: Frequency step size is 5 kHz

OR 12.5 kHz. Refer to the following guidelines:

• For VHF 5 kHz step size, transmit frequency

range is 150.000 to 164.995 MHz.

• For VHF 12.5 kHz step size, transmit frequency

range is 150.000 to 164.9875 MHz.
