3.1 Battery verification

PROLITE-23 series palm optical instruments use an alkaline battery. Before use
of the instrument, make sure the battery is correctly installed.
When the battery power is low, low battery indicator is shown on LCD. As long as
there is any character on LCD, the instrument can still be in operation. However, when
LCD turns dark, the output power becomes unstable, therefore measured power value
will not be accurate and in consequence, the measurement accuracy is degraded.
NOTE: See Maintenance section to install or replace the battery.

3.2 Turn off Auto-off function

With default setting, the Auto-off function of PROLITE-23 series palm optical fibre
tester is on, for this can conserve power and battery life. When starting up the
equipment, appears on display the message "AUTO OFF " Auto-off function needs to be
turned off, when long-time test is performed. Please follow the following procedures.
Turn off Auto-off
•
PROLITE-23 when power on the instrument, hold [On/Off] until letter "P" is
displayed on LCD to disable Auto-off. In the coming measurement, "AUTO
OFF" will not be displayed on LCD. With the default setting, the series will
conserve battery life by automatically turning itself off if no keys have been
pressed for approximately 5 minutes.
