Maintaining the battery pack
Low-battery warning
See Appendix C for more information
on the Batt LED codes. When your battery pack runs low on power, the PTC
sounds five sets of three beeps, with a pause between
sets, and the Batt LED glows solid red. When you
hear or see these warnings, promptly recharge the
PTC’s battery pack.
Operating the PTC with the AC or vehicle
adapter connected
When the 15 VDC, 2.7 A AC or vehicle adapter is
attached to the PTC, the unit draws its power from
the electrical outlet or a vehicle’s power source, not
from the PTC’s battery pack. As a result, the PTC can
remain on and be operated while its lithium-ion
battery pack is being fully charged.
Recharging the battery pack
The PTC’s lithium-ion battery pack can be recharged
via an AC adapter, a vehicle adapter, a
communication cradle, or a connector pod. Charge the
PTC’s battery pack before you use the unit for the
first time and whenever the PTC’s Batt LED glows
red to indicate a low-battery warning.
A lithium-ion battery pack will take
longer than 1.5 to 2.5 hours to
recharge if the charging process
occurs below room temperature. The PTC’s built-in charger fully recharges a depleted
battery pack in 1.5 to 2.5 hours (at room
temperature). The charger senses the power
remaining in the battery pack and decreases the
charging time accordingly.
