Buzz heard when using a PZ2-8 256-Channel Preamplifier

Tech Note: TN0248
Product: RZ2
Version: Serial Numbers < 7000
Date Added: 2007-03-26

Issue

A persistent buzz is heard when power is applied to the PreAmp. This indicates that the battery in use has been fully discharged.

Solution

Turn the PreAmp off and recharge the battery. Occasionally, a buzz will be heard when the battery in use is fully charged. If this is the case, turn the unit off (set the switch to center position), and then back on. This should correct the problem.
