QUICK ASSIST

PROGRAMMABLE FEATURES ...............................................................................................................................

QC or DQC Code

Select from a list of QC and DQC Codes to transmit subaudible

squelch tones for interference elimination.

The Quick Assist

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 transmit frequency.

QC Quiet Call

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 Subaudible Squelch).

DQC Digital Quiet Call

is Ritron’s digital coded squelch, and

works the same as QC, except it is a digital code that is

transmitted with the voice messages.

To identify your QC or DQC tone:

• Read-out the Tone Code of the RITRON radio you intend to

use with the Quick Assist

• Refer to your radio manual.

• Contact your radio dealer or Ritron if you are unsure about

this issue.

DQC Invert

The DQC Digital Quiet Call

code can be inverted for systems

that require inversion.

Compand

Some two-way radios have a feature referred to as

“companding”. It is a way of eliminating background hiss or

noise, making the radio sound clearer. “Companding” is a

combination of audio “compression” in the transmitter and

audio “expanding” in the receiver. The Quick Assist

can be

programmed for audio compression. To determine if your

existing 2-way radios are using the Companding feature, you

can check the radio’s User Manual, contact your radio dealer,

or call Ritron for help.

If you are unable to determine if your portable radio uses the

companding feature, we suggest the following:

1. Leave the radio in the factory default setting with no

companding.

2. Activate the transmitter of the Quick Assist

and listen to

the message from your portable radio. If the received

audio is acceptable, you should not need to set the Quick

Assist

for companding.

TX Alert Tone

By default, the Quick Assist

will transmit an alert tone before

each voice message transmission. This feature can be

disabled via the PC programmer.

Press and Hold Reset

Often it is desirable to repeat the “Assistance message”

without limitation until the call has been answered. With Press

and Hold Reset enabled the front panel push button can be

held down for 5 seconds to reset the Quick Assist

to the

standby condition.

Example: To use a Quick Assist

in a paint department, you

want it to re-transmit a message several times after a “Press

for Help” push-button is pressed. With the Quick Assist

set

for Press and Hold Reset an employee can terminate the

message transmissions, and in the process send a “Quick

Assist call cleared” message.

ANI

The “Assistance needed” and “Quick Assist call cleared”

conditions can each be programmed with a unique 1-9 digit

DTMF or 3-7 digit Selcall ANI string. The ANI will be

transmitted immediately prior to the Alert Tone and Input

message. To program an ANI string, select Selcall or DTMF

and enter the string in the value field.

Message Repeat

Number of Message Transmissions

You can set a limit to the number of times the message will be

transmitted at a scheduled interval.

Time Between Transmissions

This sets the amount of time the Quick Assist

will wait

between repeated transmissions. You can program a different

Wait Time for the “Assistance needed” condition, and for the

“Quick Assist call cleared” condition.

Example: When the “Press for Help” push-button pressed in

the paint department, an “Assistance needed in paint”

message is to be transmitted every 30 seconds for 5 minutes.

To accomplish this the Quick Assist

is programmed for 10

message transmissions with a time between transmissions

setting of 30 seconds.

The Quick Assist

is set at the factory to transmit the “Quick

Assist call cleared” message only once.

Repeat Message on each transmission

Your recorded voice message can be programmed to repeat

from one time to nine times on each Quick Assist

radio

transmission. Urgent messages may require more phrase

repeats.

Example: The Quick Assist

is to be used as an emergency

call button in a parking garage. If “Repeat on each

Transmission” is set to 3, the Quick Assist

would transmit

“Emergency in garage level 2, Emergency in garage level 2,

Emergency in garage level 2” when the front-panel pushbutton

is pressed.

Voice Messages

The Assist and Reset messages are recorded via the Input

Screen. Refer to the Recording Your Quick Talk

Messages

section of this manual for instructions on recording voice

messages. The Recorded box indicates whether or not a

message has been recorded. The Maximum Record Time for

each message is also indicated.
