1.2 User and Product Safety
! Never use strong pressure on the screen or subject it to severe impact, as the LCD
panel can crack and possibly cause personal injury. If the LCD panel is broken,
never touch the liquid inside, for such contact can irritate the skin.
! Although the TPC7050 mobile computer meets IP54 standards for water and dust
resistance, avoid prolonged exposure to rain or other concentrated moisture.
Conditions exceeding IP54 standards could result in water or other contaminants
entering the
TPC7050.
! Use onl
y the approved AC Adapter with the
TPC7050. Use of an unapproved AC
Adapter could result in electrical problems, or even cause a fire or an electrical
shock to the user.
! Be sure that only authorized suppliers are allowed to disassemble and reassemble the
device. If the device or parts are damaged due to wrong handling, the product and
parts warranty is void.
! Always make back-up copies of all important data. This is easily done using a cable
or single cradle (optional) to transfer data to the computer. The manufacturer is not
liable for any data damage or data loss caused by deletion or corruption while using
this device, or due to a drained battery.
! Lithium-ion battery packs may get hot, explode, ignite and/or cause serious injury if
abused. Please follow the safety warnings listed below.
Warnings:
! Do not place the battery pack in fire or heat the battery.
! Do not install the battery pack backwards so the polarity is reversed.
! Do not carry or store battery pack together with metal objects.
! Do not pierce the battery pack with nails, strike the battery pack with a
hammer, step on the battery pack or otherwise subject it to strong impacts or
shocks.
! Do not solder directly onto the battery pack.
! Do not expose battery pack to liquid, or allow the battery contacts to get
wet.
! Do not disassemble or modify the battery pack. The battery pack contains
safety and protection devices, which, if damaged, may cause the battery
pack to generate heat, explode or ignite.
! Do not discharge the battery pack using any device except for the specified
device. When it is used in devices other than the specified devices, the
battery pack can be damaged or its life expectancy reduced. If the device
causes any abnormal current to flow, it may cause the battery pack to
become hot, explode or ignite and cause serious injury.
! In the event the battery pack leaks and fluid gets into the eyes, do not rub the
eyes. Rinse well with water and immediately seek medical care. If left
untreated, the battery fluid could cause eye damage.
User’s Manual 3
To avoid malfunctions and to ensure years of trouble-free operation, pay attention to the
following:
General Use
Do not expose the mobile computer to areas subject to extreme heat such as direct
sunlight, near a heater, or in a car – or in areas that are very cold, humid, moist, or
dusty.
Do not expose the product to rain or water
Do not subject the product to strong impact, or throw or drop the mobile computer
from large heights. Do not allow other mechanical shocks to the product.
Cleaning Instructions
Clean the exterior by wiping it with a soft, dry cloth. Do not use much water.
Do not use thinner, white spirit or other solvents. These can discolor the case and
the keys and it has a negative effect on the lifetime of the keys.
Cleaning the Mobile Computer
Clean the scan window periodically for better reading performance, but pay
attention to not scratching the window
Cleaning the Cradle
Avoid touching the contacts in the cradle. The contacts must stay as clean as
possible to maintain optimal charging capacity. Do not use water when cleaning
the cradle. This can cause malfunction of the chargers.
Using the Mobile Computer
Avoid temperature changes. Sudden temperature changes can cause condensation
to form on the mobile computer. Using the mobile computer while condensation is
present can cause malfunction. Always wait until the condensation clears naturally
before attempting operation.
Do not leave the mobile computer in an area where static charge is accumulated or
near devices where electromagnetic emission is generated.
Do not place any object on top of the mobile computer. Do not lay the mobile
computer face down. Doing so can cause accidental operation of the power key or
[ENT] key, which can discharge your batteries or change settings you do not want
changed.
Using the Cradle
Do not place any product other than the
TPC7050 mobile computer in the cradle.
Maintenance
There are no user-serviceable parts inside the mobile computer or the cradle. So do
not try to take it apart. The manufacturer will not be liable for any damage caused
by customers. In case of a malfunction that can not be solved by the troubleshooting instructions in this manual, please consult our service department.

2.3 Installing, Replacing and Charging Batteries
Wrong use of batteries may cause serious damage to the mobile computer or to the cradle. To
avoid damage, it is important to follow the instructions.
Caution:
Insert a fully-charged battery pack before use of the mobile computer.
Never remove the main batteries while the mobile computer is turned
on.
Doing so may lose data in the mobile computer.
Use only recommended batteries.
When other batteries are used, defects or other problems can occur. Before
installing (new) batteries, please make sure you are using the recommended
batteries.
Use the right charger for batteries.
The rechargeable Li-ion
battery pack from POSline can be charged in the
cradle when either it is in the mobile computer or alone in the charging slot
in the back of the cradle.
The life of a battery pack is limited, and charging a battery pack causes
it to gradually lose its ability to maintain a charge. If your battery pack
requires frequent charging, it probably means it is time to purchase a
new one.
A fully charged backup battery can maintain memory (RAM) contents
for about 10 minutes, even when the battery pack is removed.
Strictly follow the instructions for installing, charging, and removing
the batteries.
The products are not warranted for damage, defects, malfunction, or loss of
data, resulting from incorrect use of batteries.
Required batteries:
The mobile computer needs both main battery and backup battery for operation.
Main Battery
The rechargeable battery pack is for normal operations and data storage. When the battery
pack power goes low, immediately charge it or replace it with a charged battery pack.
User’s Manual 13
Backup Battery
The built-in battery is for memory backup.
How to charge the
POSline rechargeable battery pack in the cradle
1. Make sure that the
POSline rechargeable battery pack is inserted in the mobile
com
puter. When the mobile computer is placed in the cradle, the rechargeable
battery pack charges automatically.
2. If you have a spare
POSline battery pack, you can replace the empty battery pack with
a fu
ll battery pack for continuous mobile computer operation. Put the empty battery
pack in the charging slot of the cradle. The LED (CHG) on the cradle flashes Red
and turns Green when the battery is fully charged.
When to replace or recharge the main battery
There are two conditions that you need to replace the main battery.
1. As soon as possible after the battery indicator
appears on the display.
2. Before using the mobile computer when it has not been used for an extended period.
Notes:
! Charging the Main and Backup Batteries for the First Time
It may take up to 16 hours to fully charge the empty backup battery. The
first time charge should be for at least 16 hours to insure a proper charge.
! When charging the battery pack, the Power LED on the Mobile
computer turns Red. After the battery pack is fully charged, the Power
LED turns green.

fully-charged the Battery pack and the backup battery pack and have started to use
the TPC7050. Otherwise data stored inside SDRAM memory will be lost. Please keep
in mind to turn off the power on Mobile computer when changing the main
Battery pack.
User’s Manual 17
2.4 Installing in a System
Notes:
! Exercise caution at all times when working with AC-powered equipment.
! Turn off your devices before installation.
! Because of the special pin-out of the connectors, use the cables supplied by
the manufacturer.
! Do not modify the cable provided by the manufacturer. If you need a special
cable for some cases, contact your supplier to purchase the right cables or
technical support.
System Connection (Data Communication)
The PT series portable data mobile computers let you link to a host computer through an RS232 cable or the CRD-80 cradle for data communication.
2.4.1 Via USB Cable
The PT series connects directly to the serial port of a host computer via the USB cable.
Figure 2-11 Communication through Cable
2.4.2 Via CRD-80 Cradle
The CRD-80 cradle provides two methods for data transmission: through an RS-232 cable (9pin connector for PC and 9-pin connector for mobile computer) and through a USB cable.
