OPERATION
Once you have connected your controller to a receiver / transmitter and adjusted the audio, you should then confirm its basic
repeater operation. This can be done by transmitting a carrier in the input of the repeater and observing the “NSQ” LED
turning on and off when you key and un-key. If you have enabled the Repeater Port Mode, System Command 01, you should
next see the “PTT” LED turn on while the repeater transmitter is on. Next, you can confirm the repeater audio path by listening
to yourself on the output of the repeater.
SYSTEM STATUS INDICATORS
The system status LED indicators will display the current status of the controller. During the controller power on self-test, the
RI-1 will turn on all of the status LEDs for about 1 second. These LED’s are located in the middle of the circuit board, see the
figure below.
INDICATOR DESCRIPTION / FUNCTION
NSQ
Noise Squelch; indicates when a signal is present at the receiver.
TSQ
Repeater Tone Squelch indicates when a CTCSS (Continuous Tone Controlled Squelch System) or DCS
(Digital Coded Squelch) has been enabled in the repeater tone panel and is present at the receiver.
PTT
Push-To-Talk; indicates when the controller is keying the repeater transmitter.
DTMF
Dual Tone Multi-Frequency; indicates when the controller is decoding DTMF (Touch-Tones).

DTMF COMMAND INPUT
Dual Tone Multi Frequency (DTMF) is typically used in the telephone system for dialing. The RI-1 uses DTMF as the primary
means for the owner and users to control and communicate with the repeater. DTMF is made up of eight tones with two of the
eight turned on in each of the sixteen keystrokes. DTMF is used because of the reliability and ease of use in the audio
transmission range. When sending commands to the controller, you must send each DTMF digit with a delay of 3.5 seconds or
less between digits. Then un-key the transmitter. This action is the same as the "enter" key on your computer keyboard. If the
squelch is open or not properly set, the controller will not be able to detect the un-key action. In this case you can wait for the
inter-digit timer to expire, at which time the controller will attempt to process the command. Once the command is sent, the
controller will respond with one of three actions.
1. CW “OK” is a result of a successful command.
2. CW “ERROR” is a result of an error in the data of a S-Command or macro.
3. No response, the controller did not receive the command or the command was not valid.
