Using preset search channel
What is preset search channel?
The mobile station or fixed station uses a preset channel when searching for a WIRES-X node. You can quickly find a local node by
registering (presetting) the channel frequency to the mobile station transceiver.
You can also find the nearest local node even when connecting from a mobile or fixed station at a place different from your usual
location, by using the preset search channel.

Setting the preset search channel
There are two methods to operate a WIRES-X node using a preset search channel:
●
When operating with 1 transceiver
Connect the C4FM digital transceiver to the HRI-200 RADIO 1 jack (See page 12).
When in the standby state, the preset search channel and the voice channel are monitored alternately.
When the node connects with another node or room, monitoring of the preset search channel is suspended and only transmitting/
receiving via the voice channel is performed.
●
When operating with 2 transceivers
Connect a C4FM digital transceiver for the voice channel to the HRI-200 RADIO 1 jack, and also connect a C4FM digital transceiver
for the preset search channel to the HRI-200 RADIO 2 jack (See page 12).
When in the standby state, the preset search channel and the voice channel are constantly monitored in a receive-ready state.
When a signal is received on the preset search channel, the voice channel information is transmitted to the mobile or fixed station of
the sender.
Even when the node is connected with another room or channel, the monitoring of the preset search channel continues.
