Bridge battery
!
Always suspend the PTC before
removing its battery pack.
An internal rechargeable nickel-cadmium bridge
battery provides power to protect data stored in the
PTC’s RAM memory while the battery pack is being
replaced or if it runs out of power. The bridge battery
can protect the PTC’s memory for a cumulative total
of 4 to 5 hours with the PTC suspended and the
battery pack removed. The bridge battery is
recharged automatically when the main battery pack
is recharged.
The bridge battery’s condition is checked every time
the PTC is resumed. If the bridge battery power is
low, the PTC beeps five times, and the Batt LED
blinks red. If you hear or see these warnings,
immediately recharge the unit for 5 hours.
Vehicle adapter (optional)
!
Use only the vehicle adapter
supplied by Symbol with the PTC.
Using any other vehicle adapter
could cause damage.
A 15 VDC, 2.7 A vehicle adapter may be used to
recharge the PTC’s lithium-ion battery pack and
nickel-cadmium bridge battery. The adapter plugs
into the PTC’s power jack and into a vehicle’s
cigarette lighter socket or directly to a vehicle’s
battery or fuse panel.
Refer to Appendix B for ordering
information. Three vehicle adapters are available:
• A cigarette lighter adapter for 12-volt automotive
systems.
• A wire adapter for 12-volt automotive systems.
• A wire adapter for 24-volt automotive systems.
When the vehicle adapter is attached to the PTC, the
unit draws its power from the vehicle’s power source,
not from the battery pack. As a result, the PTC can
remain on and be operated while its battery pack is
being fast charged.
