TROUBLESHOOTING GUIDE

BEFORE GOING THROUGH THE FOLLOWING CHART, BE SURE THE BATTERY PACK IS FULLY CHARGED. The

POWER LAMP should light up when the unit comes on. The POWER LAMP will grow dim as the batteries discharge.

Because of the nature of nicad batteries, the batteries may fail during use or be permanently damaged by the time the

POWER LAMP is dim enough for you to notice a change. Keep the batteries fully charged when not in use to insure

long battery life. Continuous charging will not harm the battery pack, although it is not necessary. In extreme cases a

continuous charge of two to three days may be necessary to restore a deeply discharged battery pack. If the battery

pack still will not except a charge after two to three days then the pack will need to be replaced. See page 2 for

charging instructions.

It is important to follow these steps in the sequence listed.

SYMPTOM POSSIBLE CAUSE

POWER LAMP NOT ON 1) Equipment turned off. Check Volume - On/Off control.

2) Battery pack discharged. Recharge unit.

CHARGING LAMP NOT ON WITH CHARGER

PLUGGED INTO CHARGING JACK 1) CH-40 not plugged into 110v supply.

2) 110V supply switched off or defective. Check 110VAC

outlet for voltage by plugging in a lamp or other AC device.

3) CH-40 charger defective.

NO SOUND FROM SPEAKER 1) Volume turned down. Check Volume - On/Off control.

2) Mic not plugged in.

3) Mic muted. Check mute switch on microphone body.

4) Defective mic or cable.

INTERMITTENT AUDIO OR “CRACKLING”

SOUND FROM SPEAKER 1) Defective mic or cable. Try different mic and cable.

2) Dirty cable plugs. Clean cable ends with clean alcohol and

a clean soft cloth. A brand new cord stored in a sealed

container such as a plastic bag will give off a gas that forms

a coating on the plugs (“outgassing”). This coating can

cause improper contact when the plug is connected to the

jack on the equipment. It will appear that the cord is

defective. It is a good idea to clean the cord periodically,

and after the system has been stored. Clean the plugs with

alcohol and a clean cloth.
