Model: Toyota Camry CE Year: 1998 Place: Ontario, Canada.
Problem Description: The preset tuning of the radio and clock set for the built-in radio- cassette lost after few hours.
Problem reproduction scenario:
1) I tune the radio channels for preset buttons (there are 6 preset buttons), 2) I set the clock to current time, 3) Keep the radio and clock switch turned 4) The radio and clock turned on everytime I start the car and could switch channels by using the preset button, 5) But after parking for 6/7 hours, the radio and clock doesn't turned on and all preset condition got lost, 6) If the weather is warmer, then the duration of preset condition stays a bit longer, but eventually got lost.Questions:
1) Is there any separate battery (power supply) for the radio- cassette ? 2) How to keep the channel preset and clock time be saved ?Note:
1) Even though the battery is 2-years old, I don't have any problem about starting the car even at -20C.Thanks in advance for any idea or solution.
