GENERAL OPERATING INFORMATION

This transceiver is easy to use. Please take a few mo-

ments to read through this section and familiarize

yourself with general operating information.

BEEP TONES

The transceiver responds to all button depressions with

an audible beep (unless the function is deactivated).

They are as follows:

1 short tone for any button depression (if enabled within

the Setup Menu).

3 short, rapid succession tones for confirmation.

1 long, low tone for any invalid button depressions.

GETTING STARTED

1. Make certain that an antenna is connected to the

appropriate rear panel ANTENNA ‘1’ connector. It is

important that this antenna is resonant in the 144 -

148 MHz range and is capable of handling 25 Watts

transmit RF power. An additional antenna can be

connected to the ANTENNA ‘2’ connector at this time

also, if desired.

2. Please refer to FIGURE 7 and adjust the controls as

shown.

Connect the microphone.

3. Connect the transceiver to a source of AC power.

Switch power on to the TR270 with the POWER switch.

The front panel display should light and show VFO 1

selected for Receiver ‘A’. If the upper frequency display

is not shown (Standby condition), press the

MODE

button

to display ‘VOICE’ in the lower left-hand portion of the

display. Note that the frequency is displayed.

4. Adjust the appropriate VOLUME control (‘A’ or ‘B’) for

a comfortable listening level.

5. Tune to the desired receive frequency by using one of

several methods covered in this section.

6. Adjust the SQUELCH control at any time to set the

desired received signal strength required to unmute the

audio. Usually this control is set to a point that just quiets

the receiver when not tuned to a station, and is for

example, receiving noise. Rotating the control clock-

wise requires stronger signals to open the squelch.

7. Prior to transmitting, set low, medium, or high power

for transmit by pressing the

P. OUT

button.

PLEASE NOTE: A ‘ ’ box

around ‘A’ or ‘B’ indi-

cates whether trans-

ceiver ‘A’ or receiver ‘B’

can be tuned.
