Calibration Instructions

1. Turn on the power.

2. Apply the desired reference level (nominal 0) signal to all

channels.

3. Make sure the reference level DIP sections (2 and 3) are set to the

nearest level of the input signal being applied for calibration (i.e.,

0, +4, +6 or +8). Verify that the signal applied to all four channels is

within ± 4 dB of the reference level set in DIP switches 2 and 3.

4. Place DIP Switch 1 in the down position (calibration).

5. Wait 10 seconds for the unit to update its calibration to your

settings.

6. Place DIP Switch 1 in the up position (operation) and return unit to

service.

Note:

Switch position 6 is not used.

Note:

You can only auto-calibrate the monitor once for each

power cycle. Once you have put DIP Switch 1 in the

calibration position, you must cycle the power before

that DIP switch will be functional again, even if a

calibration attempt was unsuccessful.

If you want to re-calibrate, turn off the power to the unit

and repeat steps 1 through 6.
