TEST MODE [setting method] While pressing INPUT SELECTOR key, plug the AC power cord into an AC outlet (K, P type) or turn on the AC POWER switch. When a set is set up in test mode condition a set becomes the following condition. Automatic POWER ON. All indicator tube (FL) and 6 CLIP INDICATOR LED are lighted. The other LED are flashed. A backup at the thing except ON/OFF of POWER is initialized. [cancel method] The power supply is turned off.
