(5) Coin type lithium battery (See page. 1-23 through 1-25)

When using the calendar function or SRAM memory (for battery backup of sampling data or

other data), make sure to set the battery.

SRAM memory data or the contents of the calendar are not restored if the battery power is not

supplied.

A lithium battery has its expiration date. Expiration date is usually five years (at ambient

temperature of 25 C). If the battery is used at high temperatures, however, the battery power

may be lowered sooner. When using the battery for significant use such as setting data that is

hard to recover once lost, be sure to set the alarm of the lower battery power and replace the

battery when alarmed.

Detection of lower battery power

The internal system memory, $s167, of the ZM-300 series has a function that shows the battery

condition. It is strongly recommended to build an indication lamp of lower battery power in your

screen data.

[Settings]

To build an indication lamp in an abnormal screen made with ZM-71SE:

1. In the lamp parts settings, make an indication lamp whose character sequence reads "Lower

Battery Power."

2. Select "$s167-04" for the lamp memory.

3. Put it in the appropriate screen. When the battery power is lowered, the indication lamp turns

on.
