Query: Tip to reduce interference/static

The reception of this monitor is excellent - we can hear the baby smack her lips as she starts to wake up - and having 2 receivers is VERY convenient.This monitor and others were sometimes given low marks due to problems with static. We found that older portable phones can cause static when in use and that using certain outlets produced static. So if you experience static, try different outlets and check the channel options on your portable phones.
