Operation with the aid o 1 a repeater
The Signal coming from your radio is received by the Repeater Station and then re¬
transmitted at the same time on another channel. This operation is called "Duplexing".
Your UH-088 is designed with the capability to access and use repeater stations.
Channels 01 through 08 have the option to operate in Duplex Mode. When any of
these channels are set to operate in duplex mode during transmission, the UH-088
automatically sends the signal at a frequency 30 channels above the original. After
transmitting, the radio reverts back to its original operating frequency.
For example,
CHOI on Duplex Mode will Receive on CH 01 but Transmit on CH31
CH02 on Duplex Mode will Receive on CH 02 but Transmit on CH32 etc....
If you transmit on CHOI Duplex mode, you are actually transmitting on CH31, the
repeater station down-converts your signal and retransmits on CHOI.
To operate UH-088 in Duplex Mode,
eg. CHOI is being used in your area
for repeater use.
Press DUPLEX momentarily.
The DUP icon appears.
