FUNCTION- Using The UHF Radio
TRANSMIT AND RECEIVE PROCEDURE
Your UHF radio contains a transmitter and receiver. To control your exposure and ensure
compliance with the general population/uncontrolled environment exposure limits, always adhere
to the following procedure:
•
Transmit no more than 50% of the time.
•
To receive calls, release the
“(PTT) BUTTON”
on the microphone handpiece.
•
To transmit (talk), press the
“(PTT) BUTTON”
on the microphone handpiece.
When powered on and not transmitting, the radio is always in receive mode. When a signal is
received RX will display on the screen, when transmitting TX display on the LCD.
For others to receive your transmission, they must be on the same channel as you and if CTCSS
or DCS is enabled, the same sub channel must also be selected.
NOTE:
Before transmitting on a UHF channel, always listen to ensure it is not already in use.
NOTE:
Transmitting 50% of the time, or less, is important because the radio generates
measurable RF energy exposure only when transmitting (in terms of measuring standards
compliance).
NOTE:
Do not transmit between two radios that are less than 1.5m apart, otherwise you may
experience interference.
NOTE:
The UHF radio is simplex “one way at a time”. While you are speaking, you can not
receive a transmission.
NOTE:
The UHF radio is an open licence band. Always identify yourself when transmitting.
TRANSMITTING RANGE
The transmitting range will depend on the antenna, terrain, surroundings and environment, it will
be affected by obstructions such as hills, buildings and foliage. The use of duplex mode will
extend the transmission range in areas where a repeater station is present.
