UT01913ZZ_1 11/21/03 TO TRANSMIT AND RECEIVE The UH075 uses the 40 UHF-CB Channels. For your reference a list of the available channels and corresponding frequencies is printed at the end of this manual. 1. The maximum RF transmit power of UH075 is 5 watts.
With Duplex operation, the signal coming from your radio is received by the Repeater station and then re-transmitted at the same time on another channel. Your UH075 is designed with duplex capability on Channels 1 to 8. When any of these channels are set to operate in duplex mode during transmission, the UH075 automatically sends the signal at a frequency 30 channels above the original in order to access the repeater station.
UH075 will return to simplex operation. Check with your local retailer for available repeaters. SCANNING The UH075 has two types of scanning; Open Scanning (OS) and Group Scanning (GS). Scanning allows you to search for active channels programmed in the OS or GS memory.
To deactivate SCAN, press the If SCAN is deactivated while it is turned to an active channel, the UH075 will stay on that active channel. If none of the channels are active, the UH075 will reinstate the Priority channel. 5:50 PM...
, to select a lower channel. DROP-OUT DELAY While scanning, the UH075 stops at a busy channel and receives a transmission. When the received signal is over, the unit will wait for 3 seconds for the return of the signal, otherwise, the radio resumes scanning.
2. Press and hold 3. When a signal is sensed on a CTCSS CH, the UH075 stops for about 400 msecs (decode time) to decode the CTCSS code. If there is no code or the receive code does not match the one programmed on the unit, the unit resumes scanning.

UT01913ZZ_1 11/21/03 ➤ POWER SAVE Battery Save feature extends the battery life by switching the receiver circuit power ON and OFF. This feature automatically activates during standby mode (RX mode without signal). ➤ BACK LIGHTING The Liquid Crystal Display (LCD) and function keys are backlit for easy viewing at night or in low light situations.
UT01913ZZ_1 11/21/03 ➤ BUSY CHANNEL LOCK-OUT (BCL) This feature prevents accidental transmission on a busy channel. This is recommended on channels where CTCSS is being used. If the channel is "active" and the signal is coming from a non or different CTCSS code user the BCL feature will prevent you from transmitting.
