Power
AC adapter (optional)
!
Use only the AC adapter supplied
by Symbol with the PTC. Using any
other adapter could cause damage.
A 15 VDC, 2.7 A AC adapter provides power to
recharge the PTC’s lithium-ion battery pack and
nickel-cadmium bridge battery. The adapter connects
to the PTC’s power jack and to an electrical outlet via
an AC power cord. The adapter has a CEE.22
connector that accepts a wide range of AC cords with
an input voltage between 100 and 240 VAC at
50/60 Hz.
When the AC adapter is attached to the PTC, the unit
draws its power from the electrical outlet, not from
the battery pack. As a result, the PTC may remain on
and be operated while its battery pack is being fast
charged.
Battery pack
!
Never leave the PTC without the
battery pack installed. Removal of
the pack will drain the bridge battery
(even with the unit suspended).
Operating power for the PTC-2124 is provided by a
rechargeable lithium-ion battery pack.
The battery pack can be charged via an AC adapter,
vehicle adapter, desktop cradle, vehicle cradle, or
connector pod.
Replace the PTC’s battery pack after
500 charge cycles.
The amount of time during which the PTC can
operate on a fully charged battery pack depends on
the features used and on the length of time the PTC
spends communicating with the host computer. The
more the radio, backlight, PCMCIA slot(s), hard disk
drive, and optional expansion modules are used, the
sooner the battery pack will run out of power.
See Appendix C for more information
on the Batt LED codes. When battery pack power is low, the PTC sounds five
sets of three beeps, and the Batt LED glows red. If
you hear or see these warnings, promptly recharge the
battery pack.
