SAFETY NOTICES
FOR HAND-HELD PRODUCT WITH RF FUNCTIONS
CP55/CP55 G serial handheld equipment uses wireless radios that have been designed and
manufactured to meet safety requirements for limiting exposure to radio waves. When used
in accordance with the instructions set forth in this manual, the equipment has been
independently verified to not exceed the emission limits for safe exposure to radio
frequency (RF) energy as specified by EN50360 of EEC.
These limits are part of comprehensive guidelines and establish permitted levels of RF
energy for the general population. The guidelines are based on standards that were
developed by independent scientific organization through periodic and thorough evaluation
of scientific studies. The standards include a substantial safety margin designed to assure
the safety of all persons, regardless of age and health.
The exposure standard for all wireless devices employs a unit of measurement known as the
Specific Absorption Rate, or SAR; the SAR limit set by CE is 2.0W/Kg.
For trunk, the SAR value of CP55/CP55 G serial handheld is:
EEC: MAX 0.335W/Kg (CP55 G), 0.013 (CP55)
FOR UNITED STATES
THESE PRODUCT MODELS HAVE BEEN CERTIFIED IN COMPLIANCE WITH THE
GOVERNMENT’S REQUIREMENTS FOR EXPOSURE TO RADIO WAVES.
The CP55 series mobile computer has been designed to comply with applicable safety
requirements for exposure to radio waves. Your mobile computer is a radio transmitter and
receiver. It is designed to not exceed the limits* of exposure to radio frequency (RF) energy
set by governmental authorities. These limits establish permitted levels of RF energy for the
general population. The guidelines are based on standards that were developed by
international scientific organizations through periodic and thorough evaluation of scientific
studies. The standards include a safety margin designed to assure the safety of all
individuals, regardless of age and health.
The radio wave exposure guidelines employ a unit of measurement known as the Specific
Absorption Rate (SAR). Tests for SAR are conducted using standardized methods with the
product transmitting at its highest certified power level in all used frequency bands. While
there may be differences between the SAR levels of various product models, they are all
designed to meet the relevant guidelines for exposure to radio waves.
The highest reported SAR values for body-worn accessory and simultaneous transmission
are 0.76W/kg, and 1.27W/kg respectively for CP55G. The highest reported SAR values for
body-worn operation are 1.03W/Kg for CP55. For body-worn operation, the product has
been tested when positioned a minimum of 15 mm from the body without any metal parts
in the vicinity of the product.
Before a WWAN model is available for sale to the public in the US, it must be tested and
certified by the Federal Communications Commission (FCC) that it does not exceed the limit
established by the government-adopted requirement for safe exposure*. The tests are
performed in positions and locations (i.e., by the ear and worn on the body) as required by
the FCC for each model. The FCC has granted an Equipment Authorization for this phone
model with all reported SAR levels evaluated as in compliance with the FCC RF exposure
guidelines. While there may be differences between the SAR levels of various phones, all
mobile phones granted an FCC equipment authorization meet the government requirement
for safe exposure. SAR information on this phone model is on file at the FCC and can be
found under the Display Grant section of
FCC ID Q3N-CP55G. Additional information on SAR can be found on the Cellular
Telecommunications & Internet Association (CTIA) website at
* In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6
watts/kilogram (W/kg) averaged over one gram of tissue. The standard incorporates a
margin of safety to give additional protection for the public and to account for any
variations in measurements.

1.4. BATTERY
The CP55 mobile computer is fed by two batteries, main battery pack and backup battery.
The main battery is removable and replaceable from the battery chamber while the backup
battery is mounted on the main board inside the mobile computer.
When the mobile computer is shipped, the main battery is stored in a package separated
from the mobile computer, which keeps it in good condition for future use.
MAIN BATTERY
The main battery is a Li-ion 3.7V, 3300mAh battery pack, which takes around 4 hours to
charge to full. The working time of the mobile computer varies by its working states. A
battery icon seated on the taskbar will show the remaining
Main Battery Level.
See also
Main Battery Setup for installing the main battery.
BACKUP BATTERY
The backup battery is settled on the main board inside the mobile computer. It is a 15 mAh
rechargeable Lithium battery. When the main battery is absent or depleted, the backup
battery takes over to feed the mobile computer. Without the main battery, a fully charged
backup battery retains the data in the DRAM and holds the system in suspension for 30
minutes (as long as wireless modules are inactive).
The backup battery is rechargeable by the external power (through a power adapter) or
main battery pack. It takes about 8 hours to charge it to full. See
Note: When removing the main battery pack, actual data retention time will depend on the
backup battery level. Check backup battery level before replacing the main battery
to ensure your data is retained.

(2) Always turn off the mobile computer to replace the main battery pack.
(3) The battery door must be secured in place for the mobile computer to operate.
(4) Any improper handling may reduce battery life.
1.4.2. CHARGE BATTERIES
Due to shipment, it is likely that the main battery and backup battery won’t be fully charged
when you receive the package. Before setting the mobile computer to work, charge the
main battery to full by direct charging via a power adapter (with the help of a Snap-on
Charging & Communication Cable or Charging & Communication Cradle).
Some key facts about charging batteries:
Charging Time
Main battery: It takes approximately 4 hours to charge the main battery. The battery charging
LED above the touchscreen lights red during charging, and lights green when the mobile
computer is completely charged.
Backup battery: The backup battery is rechargeable by both the main battery and power
adapter. It takes about 8 hours to charge it to full, however it does not need to be fully charged
for the mobile computer to work.
Charging Temperature
It is recommended that batteries be charged at room temperature (18°C~25°C) for optimal
performance.
Charging stops when temperature drops below 0°C or exceeds 40°C. In this case the battery
charging LED will be continuously blinking in red.
Power Consumption
When all radios (802.11 a/b/g/n, Bluetooth, mobile data (HSPA), GPS) are active on battery
power, main battery level drops substantially.
In order to prevent the system from shutting down due to depletion of the main battery, we
suggest that you keep a fully charged battery for replacement or have the mobile computer
access the radios on external power.
The following guides how to charge batteries.
