Weak or Hard to Hear Audio
If.the.caller’s.voice.sounds.weak.or.soft,.the.signal.might.be.blocked.by.large.metal.objects.or.walls;.you.might.also.
be.too.far.from.the.base,.or.the.handset’s.battery.may.be.weak.
•.Try.adjusting.the.volume.of.the.earpiece.(see.page.36).or.the.audio.tone.(see.page.37).
•.Try.moving.around.while.you’re.on.a.call.or.moving.closer.to.the.base.to.see.if.the.sound.gets.louder.
•.Make.sure.the.handset’s.battery.is.fully.charged.
Noise or Static on the Line
The.most.common.cause.of.noise.or.static.on.a.cordless.phone.is.interference:.other.wireless.or.electronic.devices.
can.radiate.energy.that.disturbs.the.radio.signal.between.the.base.and.the.handset.(much.like.overhead.power.lines.
can.cause.static.on.your.car.radio)..Some.common.household.sources.of.interference.are
•.electrical.appliances,.especially.microwave.ovens.
•.computer.equipment,.especially.wireless.LAN.equipment.and.DSL.modems
•.radio-based.wireless.devices,.such.as.room.monitors,.wireless.controllers,.or.wireless.headphones.or.speakers
•.large.fluorescent.light.fixtures.(particularly.ones.that.give.off.a.“buzzing”.noise)
•.other.services.that.use.your.phone.line,.like.alarm.systems,.intercom.systems,.or.broadband.Internet.service
For.static.on.only.one.handset.or.in.a.specific.location:. For.static.on.more.than.one.handset:
•.Check.nearby.for.one.of.the.common.interference.
sources.
•.Try.moving.the.handset.away.from.a.suspected.
source,.or.try.moving.the.suspected.source.so.it’s.not.
between.the.handset.and.the.base.
•.Check.near.the.base.for.the.source.of.interference.
•.Try.moving.the.base.away.from.a.suspected.source,.
or.try.turning.off.the.source.if.possible.
•.If.you.have.any.services.that.might.use.your.phone.
line,.see.if.you.need.a.filter.on.the.phone.line.
