Battery Installation
The network of this system utilizes the proprietary JBL
Battery Installation Procedures:
1.Remove the control panel cover at the bottom of the front baffle. (refer to figures in Chapter 8)
2.Remove the package film from batteries and
put these batteries into the battery holders inside the control panel on the left. Connector is snap type and has polarities. Push up battery after making sure that polarity orientation is correct.
3.Put the control panel cover back on the baffle.
Bias is applied to capacitors which are insulation components and there is no current consumption in batteries. Thus, battery life is the same as battery life with natural discharge (about 2 years in alkaline batteries).
In order to maintain the bias effect, we recommend to replace batteries regularly in every year or two.
Only the same type of battery (006P rectangular 9V alkaline battery) must be used. This battery can be easily found at electric appliance stores and convenient stores.
*The supplied batteries are for testing the bias function, and they should be replaced with new batteries soon.
*Bias is applied to reduce distortion from components. In the event of flat battery, there is no effect on the network circuitry, and there is no symptom as no sound or intermittent sound from the system. However, you will notice the level of distortion reduction effect of the bias network circuitry after new batteries are installed.
The batteries provide a voltage bias to each of the capacitor positions in the various networks. The biasing of the capacitors is done through a large value
