Recharging the Batteries
All models, except the high-power dual carrier, use one smart lithium-ion
(Li-ion) battery. The high-power dual carrier uses two smart Li-ion
batteries.
 The charge status is shown in the taskbar (at the left of the clock).
Simply tap the battery icon for more information.
 The unit also indicates the charge status with the LED on its front panel
(see LED Indicators Description on page 10).
CAUTION
Only charge the batteries with the AC/DC power adapter (or the car
outlet adapter, when offered) provided by EXFO with your unit.
IMPORTANT
 The batteries are not charged at the factory. You must fully
charge them before using the unit for the first time. The
batteries are fully charged after a few hours or when the
battery LED indicator stops flashing.
 The time required to charge the batteries depends on various
factors such as the type of modules currently in use and the
ambient temperature.
 To ensure that the batteries function or charge properly, keep
them in temperatures between 0 °C and 40 °C (32 °F and 104 °F).
Store them between –20 °C to 60 °C (–4 °F to 140 °F).
 Do not leave a battery discharged for several days.
 After 300 cycles (approximately 18 months of use), you may
want to replace the batteries with new ones to maintain
optimal operation conditions. Otherwise, the operating time
might be reduced.
