TESTING & TROUBLESHOOTING

POWER SUPPLY

• The power supply voltage (24 VDC) and polarity should be checked at the connector of each IA-204 and

RCM-42B prior to connecting and turning the power on.

SPEAKERS

• Speakers should be tested for proper phasing (polarity) and correct wiring configuration with a multi-meter.

Verify speaker phasing (polarity) at the speaker connector to ensure maximum performance when 2 or more

rooms are combined.

IA-204

• Verify a microphone or line input is connected. If a line input is connected to the house background music or

paging system, verify that system is operative.

• Turn the IA-204 on and switch the mic/line select switch to the appropriate setting. Slowly advance the input

level control until the desired volume is reached.

IA-204P
