range.
Keep antenna vertical. Keep intercom away from metal
objects and electrical wiring. Cell phones, cordless
phones, or other radio devices may also limit range.
Intercom beeps every ten minutes.
The battery is low in the intercom. Replace with AA
Alkaline batteries or operate it with DC Adapter
(not provided). A 12 Volt, 300mA DC Adapter may be
used (center positive polarity on the round plug).
Static and feedback is heard in intercom.
The intercoms are too close to each other. A cordless
phone, cell phone, or other radio devices can also cause
static.

and a green light is on longer than 3-1/2 minutes.
The intercom is out of range. Place the intercom closer
to the other intercoms in the network, with the antenna
pointing up.
