PN-V602　HARDWARE DESCRIPTIONS

 8 – 3

■ COIN BATTERY

1

Function of coin battery

It acts as a backup battery for clock when the display main power is powered off.

2

Failure phenomenon when the battery 
becomes exhausted

The time is cleared while the display main power is off, and the time setting window of OSD 
is displayed when the main power is turned on.

3

PWB supply

It is supplied with the coin battery installed.

4

Voltage that can be judged as battery 
exhaustion

The clock can run when the voltage is 2.0V or more.

5

Usable years

The coin battery life is designed to be about 8 years.

Since the estimated product life is 5 years, the coin battery does not need to be replaced.
Therefore, it is not listed as a consumable part in the parts guide.
