Operation of Cross-Band Repeater

This product can be set into an all-function cross-band repeater by simple menu operation. This is
very useful in emergency when using a handheld device for cross-band communication in remote
region.
Please note the following prior to using the cross-band repeater function:

Consult the national laws, regulations and restrictions concerning amateur radio and make
sure such operation is permitted.

Make cautious selection of frequency pair to avoid generating harmful interference. Using
cross-band repeater may cause potential damage to the communication environment and also
seriously interfere with the operation of normal repeaters. All this may be illegal! If you do
not know the repeater frequencies used locally, one safe way is to avoid using the repeater
frequency sub-band but to use the frequency in the FM simplex operation band. You may also
inquire of local frequency administrative organ about it.

Always remember that the transmission busy/idle rate is high in repeater service, and
therefore, we recommend you to use a smaller transmission power and keep the device in
good ventilation.
The repeater may set squelch (CTCSS, coding/decoding) for each selected band so as to enable
your repeater to selectively receive calls. However, if the selected channel is so busy that it adopts
CTCSS decoding, it may be because you have not selected a proper frequency pair and this may
also cause very high potential interference to other people.
