Reminders and Indicators
The TM500A features a programmable recharge reminder as well as low-
voltage and charged indicators.
Amp-Hour Reminder
The Amp-Hour LED can be configured to flash at a specified interval
following recharge as a reminder that it is time to charge the batteries. The
range is from 1 to 99 days or it can be turned off. When the number of days
programmed into this counter is exceeded, the Amp-Hour (
Ah
) LED flashes.
The specified value remains in memory until power is removed from the
TM500A. Recharging the batteries synchronizes the % State-of-Charge and
Amp-hours meters.

in the LED display, then release the button.
2. Press and release the SELECT and RESET buttons together.
3. Press the RESET button repeatedly until the desired value appears in
the display.
