SYSTEM MODE
System mode determines what conditions are required to key the repeater and pass audio from the repeater receiver to the
repeater transmitter. When the system is in mode 0 (Off), the repeater will appear dead to the users and all functions like
telephone and auxiliary are disabled. User and S-Command are still available. When the system is off, the “SYSTEM” status
LED will also be off. All other LED’s like COS and CTCSS will still show their associated status.
SYNTAX:
01 [Mode]
MINIMUM:
0
MAXIMUM:
6
UNITS:
Mode 0 = System off.
Mode 1 = COS or carrier access only.
Mode 2 = Repeater CTCSS/DCS access only.
.
Mode 3 = COS and CTCSS/DCS access.
Mode 4 = Open squelch, the repeater will blow squelch noise.
Mode 5 = System on, repeat audio off but repeat PTT still on. Used for remote base operation.
Mode 6 = System on, repeat audio and PTT off. Used for remote base operation.
DEFAULT:
Mode 1 = COS or carrier access only.
EXAMPLE:
01 0
Turns off or disables the Repeater PTT, Auxiliary PTT, and all telephone features.
01 3
Carrier and CTCSS or DCS required to operate the repeater

RECEIVER AUDIO SOURCE MODE
Select the receiver audio source for the transmitter. The HPF (High Pass Filter) removes the CTCSS tone so that it will not
be passed to the repeater output. The LPF (Low Pass Filter) reduces bandwidth above 4.5 kHz. Use the de-emphasis filter if
you plan to drive a transmitter with PM or pre-emphasis modulation.
SYNTAX:
02 [Mode]
MINIMUM:
1
MAXIMUM:
4
UNITS:
Mode 1 = Includes a low pass filter (LPF) and a high pass filter (HPF), reject CTCSS tones.
Mode 2 = Include the low pass filter (LPF) only, pass CTCSS tones.
Mode 3 = Select the de-emphasis output for driving pre-emphasis modulation and reject CTCSS tones.
Mode 4 = Select the de-emphasis output for driving pre-emphasis modulation and pass CTCSS tones.
DEFAULT:
Mode 1, Includes a low pass filter (LPF) and a high pass filter (HPF), rejects CTCSS tones.
EXAMPLE:
02 2
LPF, Low Pass Filter only, and pass CTCSS on the repeater output.

REPEATER CARRIER DELAY TIMER
This is the time that the repeater transmitter stays keyed after the receiver input has dropped. The repeater carrier delay is set
in tenths of seconds (100 mili-second) increments.
SYNTAX:
04 [Time]
MINIMUM:
0
MAXIMUM:
255 (25.5 Seconds)
UNITS:
Tenths of Seconds (1/10 Seconds or 100 mili-seconds)
DEFAULT:
30 (3.0 Seconds)
EXAMPLE:
04 055
Set carrier delay to 5.5 seconds
04 10
Set carrier delay to 1.0 second
