Caller ID Speakerphone System 1200 (430-0967) Troubleshooting Faxback Doc. # 17736 If the system is not performing as it should, check the connection to the telephone line. Calls are automatically switched and routed through complex equipment, so you might occasionally hear noise on the line. When a call is too noisy, hang up and redial the number. If you still have problems, immediately disconnect the system from the phone line. If a phone on the same line works properly, the fault is in the system or in its installation. If you are unable to locate the problem, take your system to your local Radio Shack store for assistance. If nothing appears on the screen, replace the batteries. Lightning Your system has a built in protection circuits to reduce the risk of damage from surges in phone line or power line current. These protection circuits meet or exceed FCC requirements. However, lightening striking the phone line can damage your system. Lightning damage is not common. However, if you live in an area that has severe electrical storms, we suggest that you unplug your system during storms to reduce the possibility of damage. (/ir-12/20/95)
