2.2.1 Battery Power Level Indicator
Confirming at the Power Level Icon
The battery power level can be confirmed with the battery icon (
) displayed at the bottom left of the
LCD screen.
The battery power is indicated in four levels.
The battery power level indicator tells you when to charge the battery cartridge.
：Sufficient battery power remains.
：The battery power is partially depleted. Making early charge is recommended.
：The battery power is almost fully depleted. Charge immediately.
：The battery power is totally depleted.
Charge immediately or replace with a fully charged battery cartridge.
Confirming at the “Battery Voltage” Screen
The battery power level can also be confirmed at the “Battery Voltage” screen.
The "Battery Voltage" screen displays the battery power level in more detail than the battery icon (
that displays on the LCD screen.
Display the “Battery Voltage” screen using the following procedure.
1.
)
Hold down the SF key and press the ENT key.
The “Battery Voltage” screen displays while the keys are pressed.
About the Battery Level
 The battery power level indicator does not accurately reflect the battery residual power and should only
be used as a guideline.
 The battery power level will fluctuate due to BHT operation, and therefore disparities may
occur between the actual battery voltage and the display indicator.
 Ensure to charge the battery as soon as possible before the battery power is depleted.

 Point 

If the BHT is placed in the alphanumeric entry system in user programs, the combination of the SF
and ENT keys cannot be used for displaying the battery voltage level. This is because in the
alphanumeric entry system the SF key and ENT key are used for switching between the numeric
and alphabet entry modes.
 TIP 

In user programs, you may select the key to be used for displaying the battery voltage level
(instead of the default: combination of SF and ENT keys).

The displayed battery level shows the terminal voltage of the battery, not how much power is left.

The actual voltage level varies depending upon the operation of the BHT, so the displayed level
also may vary.
