PNI B5000 User Manual - Trouble Shooting:

If the receiver is too far from transmitter, the system cannot work 

properly. You will hear “ beep beep” sound which is Out of range alert. 

At the same time all volume LEDs flash simultaneously . In this case, 

you have to put the two units nearer to each other. 

If the receiver is too close to the transmitter, an acoustic feedback 

might be heard. In this case, you have to either put the two units a bit 

farther away from each other, or turn down the volume of the receiver. 

A background noise from the receiver may mean that the batteries are 

exhausting and they need to be replaced. Check that if power LED 

turns into orange color, it means it needs to be replaced if it is the case.

Trouble

Solution

Hearing much background noise 

when operating the baby monitor 

with batteries.

Please check if the battery 

becomes weak. It is better to 

replace for a new battery if power 

LED turns into orange color

No response from the receiver 

suddenly.

If there is no voice from the baby 

unit surrounding, the baby unit 

will stop transmitting the signal to 

the parent unit. The parent unit is 

in VOX mode (standby mode). 

When there is voice again from 

the baby unit, it will trigger the 

parent unit to work again.

Poor signal

Please make sure the baby & 

parent units are not out of range. 

In extreme case, you can try to 

change the channel by doing 

pairing.
