NOTE: Ensure you return both pots to their original position after address selection is complete, otherwise the amplifier will change its volume level to the new pot positions!

5.2.4 To Activate CAI Address Selection Procedure

Briefly press the ENTER -Switch. This push button switch (Enter - Switch) can be accessed through the 3mm hole in the front panel located between the main power switch and the LEDs.

Enter Switch

After briefly pressing the Enter-Switch the actual address will be displayed by the power LEDs.

Flashing of Power LED channel A indicates the tens,

Flashing of Power LED channel B indicates the units of the address.

For example: different address setting LED sequences:

Address	Power LED Channel A/ TENS	Power LED Channel B/ TENS

01 (factory settings)	0* flash	1* flash then short pause

25	2* flashes then short pause	5* flashes then short pause

These sequences are repeated for 30 seconds (timeout).Then the Power LEDs return to their normal function.

To change CAI address, turn the appropriate Volume Potentiometer to the required address (Volume Pot Ch A => TENS, Volume Pot Ch B => UNITS).

To adjust the address you can use the scale markings of the

potentiometers.You will find the digits 0,1,2,3,4,5,6,7,8,9 on the 10 scale

spacing .

The current selected address will be immediately displayed BUT not automati- cally stored or activated! After each turn of pot you have another 30 seconds to timeout.You can leave this procedure without saving the new address by briefly pressing the Enter-Switch or waiting for timeout (as described above). To store and activate the new address you have to press the Enter-Switch for

3 seconds. This new address is stored in an EEPROM, which holds the informa- tion even if the amp is subsequently disconnected from mains. Be sure to set the CAI-Master-PC to this new address. If not, the communication will be interrupted.
