TROUBLESHOOTING GUIDE

PROBLEM & ITEMS TO CHECK

UNIT WILL NOT TURN ON

· Is unit plugged in?

· Are batteries charged?

· Are fuses blown?

UNIT OPERATES ON AC BUT NOT BATTERY

Check battery terminals

Check Fuse in Power Receptacle. Replace if needed.

SOUND IS MUFFLED

Bass too high

Treble too low

FEEDBACK: A LOUD SQUEALING, SHRILL OR HOWLING

SOUND THAT IS SELF GENERATED

Feedback occurs when a microphone is too close to the

speaker or the microphone volume is too high, or the

microphone is pointed towards the speaker. It is also caused

by sound reflecting off hard surfaces.

Reduce or eliminate Feedback by

- Pointing the microphone in a different direction

- Keeping the microphone BEHIND the speakers

- Turn down the volume levels

POWER IS ON, BUT NO SOUND

Check main volume level.

If using wireless, be sure receiver and transmitter battery is

installed and both units are turned on.

MICROPHONE SIGNAL IS WEAK

If microphone has batteries, check batteries.

Check cables/connectors.

WIRELESS MIC DOES NOT WORK

Check that transmitter batteries are fully charged and ensure

transmitter is on.

Does yellow "signal" LED light when transmitter is turned on?

Are the transmitter and receiver on the same channel? (1-16)

WIRELESS MIC CUTS IN AND OUT

Is unit visible (line of sight) from user? If not, move unit into

view when using wireless microphone.

Does the yellow "signal" LED go out when signal drops out?

Check battery in transmitter.

SW800 MAKES BUZZING NOISE

Check cables – a damaged cable will cause this. Unplug

cables one at a time until buzzing stops.

Check for Ground loops – use a ground loop isolator where

needed.

BATTERIES WILL NOT HOLD CHARGE

Replace Main Batteries every 1-2 years if unit is not left

charging when not in use.

A full charge is best obtained when the unit is off and

plugged into the AC outlet for several hours. After a

year or two the battery may need to be replaced. Batter-

ies are available from Amplivox.

To replace the batteries use a Phillips screwdriver and

take out the 3 screws from each battery cover (there are

two batteries) on the back panel. Remove the foam

spacer, set aside. Pull out the batteries to access the

terminals.

Carefully hold the battery with one hand while you re-

move the mating connector. Replace with new battery

and push mating connector of battery wire onto the cor-

responding color/polarity. RED = POSITIVE, BLACK =

NEGATIVE.

Place the batteries back in the compartment. Replace

the foam and screw on the covers

CD DOES NOT PLAY

Is unit turned on?

Be sure CD or CD-R is loaded into tray correctly.

UNIT WILL NOT PLAY CD-R/W MEDIA.

Inspect disc for deep scratches or cracks

Check if player is in "pause" mode

CD SKIPS

· Be sure unit is steady. If it is jarred, this may occur.

· Check for scratches on disc surface
