Battery Replacement
The ESP-00 II processor contains a replaceable lithium battery for maintaining the real time clock (RTC) capability of the system. These
batteries last at least 10 years from time of production and usually do not require replacement.

• Plug in IEC power cord, check mains power.
• Verify that there is an input signal from the source. The audio card input indicator should be green (or
yellow).
• Verify that there is an output signal. The audio card output signal indicator should be green (or yellow).
• If there is an input signal (indicator green) and no output signal (indicators off), the ESP may be
muted, output levels may be down, or the unit may be completely unprogrammed. Run ControlSpace
Designer software and connect to the ESP and verify. Signals should be passing from inputs to
outputs.
• Verify that the audio card input indicator is green. If it is off, increase the source output or use the
Designer software to increase the input gain.
• If the audio card input indicator is green and the audio card output signal indicator is green, verify
there is enough gain in the amplifier.
• Verify that the audio card input signal indicators are not solid red or flashing red. If they are, reduce
the source output level or use the Designer software to reduce the input gain.
• Verify that the audio card output signal indicators are not solid red or flashing red. If they are, and the
input indicators are green, use the Designer software to reduce the output gain or any intermediary
gain in the signal path.
• If the input source signal is clean when it enters the ESP system, and the input and output indicators
are green, verify that the loudspeakers are not being overdriven and are not damaged.
• Power-cycle the unit using the rear-panel POWER switch. If the issue continues, call your Bose Sales
or Support representative.
• Connect using ControlSpace Designer software and load a valid configuration into the hardware.
• Verify that the ESP LAN port is connected to a PC.
• Verify that the Ethernet LAN connection on the PC is enabled. If it is not enabled, the Link LED on the
PC will probably be off.
• If connected to a hub or switch, check the Link LED on that device.
• If using a rear-panel network card, unplug the ESP and re-seat the card.
• Verify that the LAN settings on the TCP/IP Ethernet device you are using on the PC are set correctly:
- If not using a DHCP server, the IP address of the PC should be set manually to an unused IP
address (e.g. 192.168.0.2)
- The default IP Subnet mask is set to 255.255.255.0.
- Check firewall settings on the PC, unblock all ports
• Verify that the proper Network Interface Card (NIC) card is selected in ControlSpace Designer
software network tool.
• If using a rear-panel network card, make sure the front-panel network connection is not plugged into
the same network.
• Verify that there is not another ESP connected with the same address. If unsure, disconnect one, scan
for the remaining unit, and change its address. Repeat with the second unit.
