The SGC Building, 13737 S.E. 26th St. Bellevue, WA. 98005 USA

frequency displayed does not have an assigned channel

number, four dashes will appear on the display. This indicates

that the radio is not operating on a channel (and mode) which

13.7 Channel

Change Channel - Voice Mode

In order to change the operating channel, press the CHAN key until four

dashes appear. You will need to press it one or two times before the

dashes appear.

With the dashes displayed, type in the desired channel number with the

key pad. Then press the CHAN key a second time to enter the command.

(Refer to the Quick Reference Card)

If the channel desired is a four digit channel number, the function will be

entered automatically following input of the fourth digit.

Change Channel - Telex ModeIf the new operating channel desired involves the use of

the Telex mode, you must change the mode to Telex before attempting to

change to a SITOR channel.

This feature is incorporated into the SG-2000's software programming to

prevent accidental entry and accidental voice use of SITOR channels. Voice

on these channels could interfere with data reception.

As you can imagine, if this feature was not incorporated, it would be

possible to enter channel 812, a SITOR channel, accidentally when you

meant to enter channel 812, a semi-duplex ITU voice channel.

Use the following sequence to change to a Telex SITOR channel:

1) Set mode to TLX by pressing the “VOC/TLX” button. TLX will be

displayed on the right hand side of the LCD display.

2) Depress “CHAN” button until dashes appear. Press “CHAN” once

if CHN flag is on left of numbers, or twice if FRQ flag is on).

3) Enter the desired SITOR channel number.

4) Depress “CHAN” key to enter the channel and make it current.
