Batteries and charging
Important battery
information
Before using your rechargeable battery pack for the first
time, it must be charged for at least 8 hours. This is
necessary to ensure full battery life.
Do not leave your portable or battery pack on a battery
charger for extended periods when the batteries are fully
charged.
Do not expose the battery packs to temperatures above
40°C/104°F for extended periods.
Your portable needs a rechargeable battery pack. Battery
level is shown by the J symbol on the top right of the
display. If the batteries are very low, the display flashes G
and you hear warning beeps. Your programming will not
be lost if you replace your batteries.
Preparing the
chargers
Connect the ac adaptor plug of the power cable to the rear
of the chargers, then attach the ac adaptor to a power
source.
