Controls And Operation - Intek HR-5500 Owner's Manual

it is desired that the control be adjusted only to the point where the receiver
background noise or ambient background noise is eliminated. Turn fully
anticlockwise then slowly clockwise until the receiver noise disappears. Any
signal to be received must now be slightly stronger than the average
received noise. Further clockwise rotation will increase the threshold level
which a signal must overcome in order to be heard. Only strong signals will
be heard at a maximum clockwise setting.
3. ECHO (Inner Dual Concentric)
This switch is used to control echo effect.
4. TONE (Outer Dual Concentric)
This switch is used to control intervals of echo sound.
5. RF GAIN (Inner Dual Concentric)
This switch is for adjusting sensitivity during reception. For long distance
communications RF GAIN should be set to maximum. RF GAIN can be
reduced to avoid distortion, when your correspondent is close by and when
he does not have RF POWER. The normal setting of this function is on
maximum (fully clockwise).
6. RF POWER (Inner Dual Concentric)
Adjustment of the output power is for AM and FM mode only. Reducing the
power is allowed when communicating with a person who has no RF GAIN.
The normal position of this function is set to maximum, fully clockwise.
7. BAND SELECTOR
Rotate this switch to select A, B, C, D, E, F band of operation
8. MODE (PA/CW/AM/FM/USB/LSB)
This switch allows selecting the modulation mode PA, CW, AM, FM, LSB or
USB. Your modulation mode has to correspond with the one of your
correspondent. The mode selector changes the mode of operation of both
transmitter and receiver simultaneously.
Frequency Modulation/FM: for nearby communications on a flat open field.

Controls and Operation

Amplitude Modulation/AM : Communication on a field with relief and
obstacles in middle distance (the most used).
Upper and Lower Side Band/USB-LSB : Used for long distance
communications (according to the propagation conditions).
9. CLARIFIER
This is frequency tuning knob which can be set as different modes (refer to
CLA Specifications in Functions Menu for more details).
10. PUSH
This is PUSH Key which can be set as different modes (refer to PSH
specifications under Functions Menu for more details).
11. CHANNEL SELECTOR
Rotate this switch to select any desired channel from forty citizens band
channels. The selected channel appears on the LED directly above the
channel selector knob.
12. CHANNEL INDICATOR
Numbered LED indicates the selected channel to operate on.
13. RECEIVER/TRANSMIT INDICATOR
When it is receiving, the LED will be green. The LED will be red when it is
transmitting.
14. LCD DISPLAY
Display frequency, all kinds of information and icons.
15. FUNC
This is functional key. Press and hold this key for 2 seconds to enter into
Functions Menu Setup (refer to Functions Menu for more details).
