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.

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
