HOW TO USE WIRELESS INTERCOM I. TALK: Step 1: After receiving the call signal from another equipment, the equipment emits a series of ringing. Press TALK key to start emitting and the light become red, talk to MIC 5-10cm away from it with normal volume. After speaking, release TALK key. The another device with the same channel code receives the sound. Release TALK key after speaking and wait for reply. Step 2: After receiving the reply, if you want to continue to talk, just continue to press TALK key to start emitting, continue to talk, then release TALK key to emit the speech to another equipment. Note: 1.The intercom system is the same-frequency simplex system, which does not receive message when TALK is pressed to emit, and can not receive when TALK key is pressed in receiving. 2.TALK: It is provided with TOT function (Time out Timer), i.e. the device automatically exits emit mode after emitting for 1 minute, which is to say, the time for each talking shall not be longer than 1minute. 3.One piece of device can only talk with the same channel code at the same time node. If the channel code for multiple pieces of device are the same, these device can all receive voice information. 4.When talk ends, the channel code of calling device automatically change to the originally set channel code after 1 minute. For example, if the previous channel code is channel 1 code A, the device's channel code will automatically change to channel 1 code A 1 minute after talk ends. CH7 462.7125MHz CODE C: 734N CH8 467.5625MHz CH9 467.5875MHz CH0 467.6125MHz GROUP 462.7000MHz CODE:743N
II．CALL Please call another device by following steps 1.Step 1: Confirm the calling device's channel code is the same with that of the to-be-called device. If the to-be-called device is in channel 4 code B, you shall set the calling device's code as channel 4 code B. 2.Step 2: Press CALL key and the talk cue indicator turns red. The calling device emits a series of ringing, and the device with the same channel code receives a series of ringing that prompts reply to the calling equipment. 3.Step 3: When receiving the reply from other device, press TALK key to talk to MIC with normal volume. After speaking, release TALK key to send the speech to the another device. Similarly: To call another device, first confirm the channel code of calling and to-be-called device are the same, then follow above steps. For example: If the calling device is in channel 1 code A, while the to-be-called device is in channel 7 code B, first set the calling device's channel code as channel 7 code B, then press CALL key to call. NOTE:When talk end, the channel code of calling device automatically change to the originally channel code after 1 minute. For example, if the previous channel code is channel 1 code A, the device's channel code will automatically change to channel 1 code A 1 minute after talk end. III.VOX （Voice Operated Exchange） VOX: Press VOX key and channel number indicator flashes to prompt that currently the VOX state is enabled. Talk to MIC or surroundings to activate starting and emitting with sound, the emitting indicator becomes red, the sound content will be sent to the device with the same channel code. There is a time lag of 2 second after speaking. It will work 24 hours per day.Press any key to cancel VOX function. IV. MONITOR MONITOR: Put the equipment in the to-be-monitored place, press MONITOR key and the equipment goes into state of emitting. The monitor time is 10 hours only. Description: 1.The MONIOTOR function is similar to VOX sound control and TALK function, that is to set the device as always in emitting state but not need to press TALK key to automatically emit the received speech content. 2.Use range: It can be placed in room needing to be monitored emphatically,
such as kindergarten, baby's room, game room, the elder's room, ward, etc. 3.When you press MINITOR key, the emit indicator becomes red, indicative of setting success, then the device will be monitored by another device with the same channel code. 4.Use method: For example, to monitor a baby's room, just put the equipment in the baby's room, press MONITOR key, then you can monitor it in another room via the device with the same channel code. 5.The MONITOR will automatically terminate 10 hours later, so a knowledge of the starting time you set is more favorable for your monitoring. 6.The TALK key indicator on the device receiving monitored voice will turn red when receiving the voice, meaning voice is transmitting. V:GROUP（Group-Call Function） Step 1: Press GROUP key, and the whole intercom system can receive the voice message no matter what channel code of the device is in. When the device is receiving group-call signal, all the channel number indicators of equipment flash. Step 2:When other equipment reply, press GROUP key and talk with normal volume.After talking,then release the key,the speech will be send out. Note: The group-call function entails to press GROUP key for talking to establish group-call instead of pressing TALK key. SET CHANNEL CODE Please set different channel codes for different device by following steps, then these different devices within a wireless intercom system can talk with others. Example: If you want to set your device as in channel 2 (General Manager Room) Step 1: Connect power and start, the device emits a starting cue tone of "Du", the factory default channel code is channel 1 code A, then the channel 1 light turns blue. Step 2: Long press channel 2 for 3 second, when hear a cue tone of "Bi", channel 2 light turns blue, then release the key. The channel 2 light turns blue,meaning the device has been set as channel 2. This also means the equipment in the general manager's room is in channel 2. Step 3: If you need to place the device in other offices and set channel, such as setting financial department as in channel 3, HR department as in channel 4, sales department as in channel 5, please follow above step 1 and step 2. Note: 1.If you desire to talk with all equipment at the same time, please set the came channel code of all device or use GROUP function. 2.To communicate with a single piece of device, just set the device as different channel code, i.e. set channel code in all office/room as different. 3.When the calling device calls another device, the called device cannot
recognize the calling device's channel code, so please first indicate the channel code of device, i.e. your identity when calling another device. 4.Please keep digital code consistent in setting channels, for example: all equipment uses code A or code B, and please record the channel code of each office/room, to enable you to rapidly and accurately call others. Channel: 2 3 4 5 Code: A A A A Device Location General Manager Room Financial Department HR Department Sales Department Connect Device of Other Brands: If the device’s channel code of other brands is the same with any channel code of our device, you can connect it for talking via the same channel code by adding the device of other brands into our wireless intercom system.
