3. Remove the new battery from its package. Keep the package for future
use. Plug in the electrical connector ensuring the pins are correctly
aligned. Place the new battery in the MaxTester.
4. Inspect the inside rib around the MaxTester battery compartment to
make sure it is free from any debris. Remove any debris using a dry
cloth. Replace the battery back panel. Replace the 4 screws with a
moderate torque so the foam seal is evenly compressed without
damaging the screws.
Battery Charging and Replacing
Charging the MaxTester single battery can take up to 5 hours. This battery
was custom made for your unit; replacement batteries must be ordered
from EXFO. Charging the dual battery can take up to 3.5 hours (based on
an ambient temperature of 23
o
C and in suspend mode).
WARNING
The dual battery is only replaceable by an EXFO Service Center or
Certified Service Center. See Contacting the Technical Support
Group on page 426 for information on contacting EXFO.
