3. The Squelch Settings Screen is now displayed with two

options “IC1 Squelch” and “IC2 Squelch” and a bar level

indicating their current status.

4. Use the <UP>/<DOWN> buttons to navigate the cursor to

the desired setting to modify and press <SET> to select it.

Both the cursor and the number will flash indicating that the

level is ready to be modified.

5. Use the <UP>/<DOWN> buttons to move the bar level up

and down and change the corresponding squelch level

6. When the desired level is flashing, press <SET> to select it.

The cursor and number will stop blinking indicating that the

level has been set.

7. At this point, the user has four options.

a. Press <SET> again to re-adjust the same level (return to

Step 5).

b. Use the <UP>/<DOWN> buttons and navigate to

another selection to modify (return to Step 4).

c. Press the <MENU> button to go back one menu screen

(return to Step 2).

d. Press and hold the <MENU> button for 1/2 second to

return directly to the Status Screen.

NOTE: The squelch setting never disables the base station

wireless transmitter. The base station continues to

transmit data regardless if the squelch level is met or

exceeded.

External Audio Interface Settings

The base station can be configured to work with several different

external audio interfaces including:

•

2-Wire Intercom

•

4-Wire Intercom

•

Auxiliary Input

•

Auxiliary Output

•

Speaker Output

2-Wire Intercom

The BTR-240 base station has the ability to interface to two,

2-wire external audio intercom systems. As shown in Figure

5-12, these XLR jacks are designated as “Intercom 1” and

“Intercom 2” on the rear panel. They accept RTS, Audiocom

(Telex) and Clear-Com types of intercom systems. The hardware

specifications and pinouts for each of these intercom types will

vary. It is important to ensure that the cables are wired correctly

for proper system operation. Refer to Section 11 for the 2-wire

hardware specifications and pinouts for each of these intercom

types.

The 2-wire intercom may be used at the same time as the 4-wire

intercom.

The base station does not require “wet” intercom lines for

operation. Wet intercom lines are those with D.C. voltages on

them for powering 2-wire devices. The base station will loop thru

wet intercom lines with currents up to 2 Amps.

CAUTION:

Do not loop thru more than 2 Amps of current. Damage to the

base station may occur.

CAUTION:

Only connect and remove 2-wire connections from the

BTR-240 when the settings have been turned “off”.

Operating the BTR-240 while 2-wire settings are active and

without the proper system load could result in undesirable

audio quality including potentially loud audio bursts.
