3 of message box for record - Auto Message send out at 15/30/45mins -Up to 180 seconds total recording time -DTMF remote control for all functions. A simplex repeater can be set up with a single handheld radio and operated from batteries. This makes it perfect for disaster response, home or campground use, and any place where radio range needs to be extended but the cost and complexity of a traditional repeater can’t be justified.Auto message send system 15/30/45 minutes setting. A simplex repeater records incoming transmissions and retransmits them on the same frequency. This has the effect of doubling the time required to transmit a message, while a traditional repeater typically costs thousands of dollars and might be semi-portable at best. The SR-112 s voice mail function operates like a telephone answering machine, allowing users to record messages for later retrieval. Up to 3 incoming messages can be recorded, total recording message up to 180sec. The SR-112 is a multi-function voice recorder device that connects to virtually any handheld, base, or mobile radio. It features exceptional voice recording quality and higher capacity than any other comparable device on the market.
